Welcome

Getting Started
Welcome
Thank you for choosing the Wireless-N Gigabit Security Router with VPN. The Wireless-N Gigabit Security Router with VPN is an advanced Internet-sharing network solution for your small business needs. The Router features a built-in 4-Port full-duplex 10/100/1000 Ethernet switch to connect four PCs directly, or you can connect more hubs and switches to create as big a network as you need. Like any wireless router, it lets multiple computers in your office share an Internet connection through both wired and wireless connections. It can also be used as an intranet router to aggregate traffic to a company backbone network.
The Router has a built-in access point that supports the latest 802.11n draft specification by IEEE. It also supports 802.11g and 802.11b clients in a mixed environment. The access point can support an 11n data rate of up to 300 Mbps. Besides having a higher data rate, 802.11n technology also promises longer coverage by using multiple antennas to transmit and receive data streams in different directions. Users are encouraged to upgrade their firmware through www.linksys.com when 802.11n specification is finalized by IEEE to ensure compatibility with all the wireless-N devices.
The Wireless-N Gigabit Security Router with VPN is equipped with advanced security technologies like Intrusion Prevention System (IPS), Stateful Packet Inspection (SPI) Firewall, IP based Access List (IP ACL), and Network Address Port Translation (NAPT, also called NAT as a more generic term). These technologies work together by providing self-defensive strategy. Malicious attack traffic is identified, classified, and stopped in real time while passing through the Router. Users are encouraged to update their IPS signature file to stay current on stopping malicious worms. The SPI Firewall provides deep packet inspection to analyze packets in network layer (IP) and transport layer (TCP, UDP) to block illegal packet transactions. Users can also use IP based ACL to limit traffic to a specific source, destination and protocol. NAPT allows users to open specific TCP/UDP port numbers to the Internet to provide limited service while minimizing harmful traffic at the same time.
The Virtual Private Network (VPN) capability is another security feature that creates encrypted “tunnels” through the Internet, allowing up to five remote offices and five traveling users to securely connect into your office network from off-site. Users connecting through a VPN tunnel are attached to your company's network with secure access to files, e-mail, and your intranet as if they were in the building. You can also use the VPN capability to allow users on your small office network to securely connect out to a corporate network. The QoS features provide consistent voice and video quality throughout your business.
This user guide will give you all the information you need to connect, set up, and configure your Router.

Networking and Security Basics

An Introduction to LANs

Networking and Security Basics
An Introduction to LANs
A Router is a network device that connects multiple networks together and forward traffic based on IP destination of each packet.
The Wireless-N Gigabit Security Router can connect your local area network (LAN) or a group of PCs interconnected in your home or office to the Internet. You can use one public IP address from the ISP through WAN port and use the router’s Network Address Translation (NAT) technology to share this single IP address among all the users.
The Router’s Network Address Port Translation (NAPT or NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.
Multiple Wireless-N Gigabit Security Routers can also be used to connect multiple LANs together. This usually applies to a medium-sized or larger company where you want to divide your network into multiple IP subnets to increase the intranet throughput and reduce the size of the IP broadcast domain and its interference. In this case, you need one WRVS4400Nv2 for each subnetwork and you can connect all the WAN ports to a second level Router or switch to the Internet. Note that the second level Router only forwards data packets through a wired network so you don’t have to use the Wireless-N Gigabit Security Router. You can use any wired router in the Linksys family, e.g. RVS4000, which has 4 LAN ports and 1 WAN port.
The following diagram shows an example that consists of two levels of routers and multiple LANs inter-connected together. The wireless network is only available at the first level of router to provide end user connections. The second level router can connect to dedicated Server PCs or routers that aggregates traffic from different LANs.

Networking and Security Basics

The Use of IP Addresses

Example network
The Use of IP Addresses
IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections.
NOTE: Since the Router is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the Internet. In this User Guide, you’ll see references to the “Internet IP address” and the “LAN IP address.”
NOTE: Since the Router uses NAT technology, the only IP address that can be seen from the Internet for your network is the Router’s Internet IP address. However, even this Internet IP address can be hidden on the Internet by suppressing PING response.
There are two ways of assigning IP addresses to your network devices.
A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with dedicated network devices such as server PCs or print servers. Since a user’s PC is moving around in a network and is being powered on or off, it does not require a dedicated IP address that could be a precious resource in your network.
WRV S440 0N Us er Guid e 7
Networking and Security Basics
The Use of IP Addresses
If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get the information from your ISP.
A dynamic IP address is automatically assigned to a device on the network. This IP address is called dynamic because it is only temporarily assigned to the PC or other device. After a certain time period, it expires and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address. Most ISPs use dynamic IP addresses for their customers. By default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP).
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is a dedicated, high-speed connection type called Point-to-Point Protocol over Ethernet (PPPoE). PPPoE is similar to a dial-up connection, which establishes a PPP session with an ISP server through the DSL connection. The server will also provide the Router with a dynamic IP address to establish a connection to the Internet.
A DHCP server can either be located on a designated PC on the network or another network device, such as the Router. The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. For this Wireless-N Router, a DHCP client is running on a WAN port for most configurations. A DHCP server is running on the LAN side to provide services.
By default, a DHCP server is enabled on the Router. If you already have a DHCP server running on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router, refer to the Basic Setup section in “Chapter 6: Setting Up and Configuring the Router.”

The Intrusion Prevention System (IPS)

The Intrusion Prevention System (IPS)
IPS is an advanced technology to protect your network from malicious attacks. IPS works together with your SPI Firewall, IP Based Access List (IP ACL), Network Address Port Translation (NAPT), and Virtual Private Network (VPN) to achieve the highest amount of securities.
IPS Scenarios
IPS works by providing real-time detection and prevention as an in-line module in a router. The Wireless-N Security Router has hardware-based acceleration for real-time pattern matching for malicious attacks. It actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. This protects your client PCs and servers running various operating systems including Windows, Linux, and Solaris from network worm attacks. However, this system does not prevent viruses attached emails.
The P2P (peer to peer) and IM (instant messaging) control allows the system administrator to prevent network users from using those protocols to communicate with people over the Internet. This helps the administrators to set up company policies on how to use their Internet bandwidth wisely.
The signature file is the heart of the IPS system. It is similar to the Virus definition files on your PC’s Anti-Virus programs. IPS uses this file to match against packets coming in to the Router and performs actions accordingly. As of today, the Wireless-N Router is shipped with signature file version 1.3.8 and with a total of 1101 rules. The rules cover the following categories: DDoS, Buffer Overflow, Access Control, Scan, Trojan Horse, Misc., P2P, IM, Virus, Worm, and Web Attacks.
Customers are encouraged to update their IPS signature file regularly to prevent any new type of attacks on the Internet.

Planning Your Virtual Private Network (VPN)

Why do I need a VPN?

Planning Your Virtual Private Network (VPN)
Why do I need a VPN?
Computer networking provides a flexibility not available when using an archaic, paper-based system. With this flexibility, however, comes an increased risk in security. This is why firewalls were first introduced. Firewalls help to protect data inside of a local network. But what do you do once information is sent outside of your local network, when e-mails are sent to their destination, or when you have to connect to your company's network when you are out on the road? How is your data protected?
That is when a VPN can help. VPNs are called Virtual Private Networks because they secure data moving outside of your network as if it were still within that network.
When data is sent out across the Internet from your computer, it is always open to attacks. You may already have a firewall, which will help protect data moving around or held within your network from being corrupted or intercepted by entities outside of your network, but once data moves outside of your network—when you send data to someone via e-mail or communicate with an individual over the Internet—the firewall will no longer protect that data.
At this point, your data becomes open to hackers using a variety of methods to steal not only the data you are transmitting but also your network login and security data. Some of the most common methods are as follows:
1) MAC Address Spoofing
Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header. These packet headers contain both the source and destination information for that packet to transmit efficiently. A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user.
2) Data Sniffing
Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text.
3) Man in the middle attacks
Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the middle” attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the data to a new destination. Even though the data is not received by its intended recipient, it appears that way to the person sending the data.
These are only a few of the methods hackers use and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the

Planning Your Virtual Private Network (VPN)

What is a VPN?

Internet. Data travelling over the Internet will often pass through many different servers around the world before reaching its final destination. That's a long way to go for unsecured data and this is when a VPN serves its purpose.
What is a VPN?
A VPN, or Virtual Private Network, is a connection between two endpoints—a VPN Router, for instance—in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks.
This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection secured by encrypting the data sent between the two networks.
There are two popular ways to establish a secured tunnel over the Internet — IPsec (IP Security) and SSL (Secure Sockets Layer). IPsec runs on top of the IP layer and SSL runs over HTTP sessions. IPsec provides better data throughput and SSL offers ease of use without the need of VPN client applications. The Wireless-N Gigabit Security Router supports IPsec VPN for maximum throughput on data security.
VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniques—IPsec, short for IP Security—the VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual Private Networking can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer with the Linksys VPN client software.)
NOTE: You must have at least one VPN Router on one end of the VPN tunnel. At the other end of the VPN tunnel, you must have a second VPN Router or a computer with the Linksys VPN client
There are two basic ways to create a VPN connection:
VPN Router to VPN Router
Computer (using the Linksys VPN client software) to VPN Router
The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with the Linksys VPN client software can be one of the two endpoints (refer to “Appendix C: Using the Linksys QuickVPN Software for Windows 2000 or XP”). If you choose not to run the VPN client software, any computer with the built-in IPsec Security Manager (Microsoft 2000 and XP) allows the VPN Router to create a VPN tunnel using IPsec (refer to “Appendix C: Configuring IPsec between a Windows 2000 or XP PC and the Router”). Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPsec to be installed.

An example of a VPN Router-to-VPN Router VPN would be as follows. At home, a telecommuter uses his VPN Router for his always-on Internet connection. His router is configured with his office's VPN settings. When he connects to his office's router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office's network, as if he were physically connected. For more information, refer to “Appendix C: Configuring a Gateway-to-Gateway IPsec Tunnel.”

Computer (using the Linksys VPN client software) to VPN Router

The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman dials up her ISP. Her notebook computer has the Linksys VPN client software, which is configured with her office's IP address. She accesses the Linksys VPN client software and connects to the VPN Router at the central office. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office's network, as if she were physically connected.

Connecting the Router

Overview

To set up your network, you will do the following:
Connect the Router to one of your PCs according to the instructions in this chapter.
By default, Windows 98, 2000, Millennium, and XP computers are set to obtain an IP
address automatically, so unless you have changed the default setting, then you will not need to configure your PCs. (If you do need to configure your PCs, refer to Windows Help for more information.)
Set up and configure the Router with the setting(s) provided by your Internet Service
Provider (ISP) according to
Chapter 6, "Setting Up and Configuring the Router".
Overview
The installation technician from your ISP should have left the setup information with you after installing your broadband connection. If not, you can call your ISP to request the information. Once you have the setup information for your specific type of Internet connection, then you can begin installation and setup of the Router.

Setting Up and Configuring the Router
Overview
The Wireless Router has been designed to be functional right out of the box with the default settings. However, if you'd like to change these settings, the Wireless Router can be configured through your web browser with the Web-based Utility. This chapter explains how to use the Utility to perform the most basic settings.
The Utility can be accessed via web browsers, such as Microsoft Internet Explorer or Mozilla Firefox through the use of a computer that is networked with the Wireless Router.

Basic Setup

For a basic network setup, most users only need to use the following screens of the Utility:
Setup->WAN
Click the Setup tab and then select the WAN screen. Select the appropriate Internet Connection Type according to your ISP if connecting your WAN port to the WAN (DSL or cable modem). Otherwise, most cases can leave the default setting to get a WAN port IP address from a DHCP server.
Setup->Advanced Routing
Click the Setup tab and then select the Advanced Routing screen. If you are connecting the Router to the Internet, leave the default setting. Otherwise, choose the Router Operation Mode to disable NAT (Network Address Translation).
Management
Click the Administration tab and then select the Management screen. Change the access password for the Router’s Web-based Utility. The default username and password are admin.
Most users will also customize their wireless settings:
Wireless
On the Wireless screen, change the default SSID on the Basic Settings Tab. Select the level of security under the Security Settings Tab and complete the options for the selected security mode. When the appropriate security mode is configured, disable
SSID Broadcast on the Basic Settings Tab.

How to Access the Web-based Utility

There are two ways to connect to your Wireless Router for the first time.
1. Connect your PC to one of the four LAN ports on the Router. (Refer to "Chapter 5: Connecting the Router.") Then, configure your PC to obtain IP address automatically through a DHCP server.
2. Although it is not recommended, you can also connect your PC wirelessly to the Wireless Router. Then, configure the wireless interface of your PC to obtain IP address automatically

Static Routing
Some ISPs require static routes to build your routing table instead of using dynamic routing protocols. Static routes do not require CPU resources to exchange routing information with a peer router. You can also use static routes to reach peer routers that do not support dynamic routing protocols. Static routes can be used together with dynamic routes. Be careful not to introduce routing loops in your network.
To set up static routing, you should add route entries in the routing table that tell the Router where to forward packets to specific IP destinations.
Enter the following data to create a static route entry:
1. Select Set Number—Select the set number (routing table entry number) that you wish to view or configure. If necessary, click Delete This Entry to clear the entry.
2. Destination IP Address—Enter the network address of the remote LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP; the last field should be zero.
3. Subnet Mask—Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP domains, the Subnet Mask is 255.255.255.0.
4. Gateway—If this Router is used to connect your network to the Internet, then your gateway IP is the Router's IP Address. If you have another router handling your network's Internet connection, enter the IP Address of that router instead.
5. Hop Count (max. 15)—Gives the number of routers that a data packet passes through before reaching its destination. It is used to define the priority on which route to use if there is a conflict between a static route and dynamic route.
Show Routing Table button—Click this button to show the routing table established either through dynamic or static routing methods.
Inter-VLAN Routing
Inter-VLAN Routing—Select Enable to allow packets to be routed between VLANs that are in
different subnets. The default is Enable.

network.
6to4 Tunnel—Allows your IPv6 network to connect to other IPv6 networks via tunnels through IPv4 (per RFC3056). The remote router also needs to support 6to4 as well. Since the tunnel can be automatically formed based on traffic, there is no limit on how many tunnels you can have.
6to4 Gateway Access Control—By default, this route allows 6to4 connections to or from any other 6to4 gateway. By enabling this Access Control, you can have a better control which IPv6 clouds this router is connecting to. A list of IP addresses can be entered in the Access List. Those should be the IPv4 addresses of the remote 6to4 gateways.
Permit following sites—Allow only a limited set of 6to4 gateways to establish tunnel
with the router. Up to 20 sites can be configured and they can send traffic simultaneously.
Block following sites—Prevent a limited set of 6to4 gateways from establishing
tunnels with the router. Up to 20 sites can be configured.
Static 6to4 DNS entry—Allow users to configure static DNS entry to map hostname to IPv6 address. This will provide a convenient way for users to access remote IPv6 hosts.

Advanced Wireless Settings

Configure the advanced settings for the Wireless Router. The Wireless-N Router adopts several new parameters to adjust the channel bandwidth and guard intervals to improve the data rate dynamically. Linksys recommends to let your Wireless Router automatically adjust the parameters for maximum data throughput.
Advanced Wireless
You can change the following advanced parameters (some only for Wireless-N) for this Wireless Router. Wireless-N data rates are classified into 16 MCS numbers (0-15). MCS stands for Modulation and Coding Scheme. For the same MCS number, the data rate changes according to the Channel Bandwidth and Guard Interval settings. You can see the change through the drop-down menu of Tx Rate Limiting (11n clients).
Channel Bandwidth—Select the channel bandwidth manually for Wireless-N connections. When it is set to 20MHz, only the 20MHz channel is used. When it is set to 40MHz, Wireless-N connections will use 40MHz channel but Wireless-B and Wireless-G will still use 20MHz channel. The default is Auto.
Guard Interval—Select the guard interval manually for Wireless-N connections. The two options are Short (400ns) and Long (800ns). The default is Auto.
CTS Protection Mode—CTS (Clear-To-Send) Protection Mode function boosts the Wireless Router’s ability to catch all wireless transmissions, but will severely decrease performance. Keep the default setting, Auto, so the Wireless Router can use this feature as needed, when the Wireless-N/G products are not able to transmit to the Wireless Router in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature.
Beacon Interval— Indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Wireless Router to keep the network synchronized. A beacon includes the wireless networks service area, the Wireless Router address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). The default is 100 ms.

IP Based ACL

This screen shows a summary of configured IP based Access List. The Access List is used to restrict traffic going through the Router either from WAN or LAN port. There are two ways to restrict data traffic. You can block specific types of traffic according to your ACL definitions. Or you can allow only specific types of traffic according to your ACL definition. The ACL rules will be read according to its priority. If there is a match for a packet, the action will be taken and following lower priority rules will not be checked against this packet.
Note that the higher the number of rules that need to be checked against packets, the lower the throughput. Use ACL rules with caution.
There are two default rules in the table that cannot be deleted. The first rule will allow all traffic coming in from LAN port to pass the Router. The second rule will allow all traffic coming in from WAN port. These two rules have the lowest priority, so without adding any user defined rules, all the packets can be passed through from both WAN and LAN sides.
The rule will be enabled when the Enable button is checked, and when Date and Time are matched. If any of conditions are not met, the rule will not be used to check against packets.
The following are descriptions on each of the fields in the ACL Table:
WRV S440 0N Us er Guid e 59

the Internet, the NAT Router will forward those requests to the appropriate servers on your LAN.
Application—Enter the name of the application you wish to configure.
External Port—Port number used by the service or Internet application. Internet users must
connect using this port number. Check with the software documentation of the Internet application for more information.
Internal Port—Port number used by the Router when forwarding Internet traffic to the PC or server on your LAN and is usually the same as the External Port number. If it is different, the Router performs a Port Translation, so that the port number used by Internet users is different from the port number used by the server or Internet application.
For example, you could configure your Web Server to accept connections on both port 80 (standard) and port 8080. Then, enable Port Forwarding, set the External Port to 80 and the Internal Port to 8080. Now, any traffic from the Internet to your Web server will be using port 8080, even though the Internet users used the standard port, 80. (Users on the local LAN can and should connect to your Web Server using the standard port 80.)
Protocol—Select the protocol used for this application, TCP and/or UDP.

This is one of the NAPT (Network Address Port Translation) features. The Port Range Forwarding screen allows you to set up public services on your network, such as web servers, ftp servers, e­mail servers, or other specialized Internet applications that use one or multiple port numbers (e.g. video conference). The port numbers being used will not change while forwarding to the local network. This allows users on the Internet to access this server by using the WAN port IP address and the pre-defined port numbers. When users send these types of requests to your WAN port IP address via the Internet, the NAT Router will forward those requests to the appropriate servers on your LAN.
Application—Enter the name of the application you wish to configure.
Start—The beginning of the port range. Enter the beginning of the range of port numbers
(external ports) used by the server or Internet application. Check with the software documentation of the Internet application for more information if necessary.

Keying Mode—The router supports both IKE with Preshared Key (automatic) and Manual
key management. When choosing automatic key management, IKE (Internet Key Exchange) protocols are used to negotiate key material for SA. If manual key management is selected, no key negotiation is needed. Basically, manual key management is used in small static environments or for troubleshooting purpose. Notice that both sides must use the same Key Management method.
Encryption—The Encryption method determines the length of the key used to encrypt/ decrypt ESP packets. 3DES is supported. Notice that both sides of the VPN tunnel must use the same Encryption method.
Authentication—Authentication determines a method to authenticate the ESP packets. Either MD5 or SHA1 may be selected. Both sides of the VPN tunnel must use the same Authentication
method.
MD5—A one way hashing algorithm that produces a 128-bit digest.
SHA1—A one way hashing algorithm that produces a 160-bit digest.
Preshared Key— IKE uses the Pre-shared Key field to authenticate the remote IKE peer. Both character and hexadecimal value are acceptable in this field. for example; "My_@123" or "0x4d795f40313233". Both sides must use the same Pre-shared Key.
Key Lifetime—Specifies the lifetime of the IKE generated key. If the time expires, a new key will be renegotiated automatically. The Key Lifetime may range from 1081 to 86400 seconds. The default value for Phase 1 is 28800 seconds, and default value for Phase 2 is 3600 seconds
Group— For Diffie-Hellman key negotiation. There are 3 groups available for ISAKMP SA establishment, 768-bit, 1024-bit, 1536-bit represent different bits used in Diffie-Hellman mode operation. The default value is Group 768-bit.

Perfect Forward Secrecy— If PFS is enabled, IKE Phase 2 negotiation will generate a new key material for IP traffic encryption and authentication. Note: that both sides must have this selected.
Preshared Key— This field specifies a key used to authenticate IP traffic. Both character and hexadecimal value are acceptable in this field. Note: that both sides must use the same Authentication Key.
Inbound SPI/Outbound SPI—The SPI (Security Parameter Index) is carried in the ESP header. This enables the receiver to select the SA, under which a packet should be processed. The SPI is a 32-bit value. Both decimal and hexadecimal values are acceptable. e.g. "987654321" or "0x3ade68b1". Each tunnel must have unique an Inbound SPI and Outbound SPI. No two tunnels share the same SPI. Notice that Inbound SPI must match the other router's Outbound SPI, and vice versa
