VRRP protocol Increases the availability and reliability of routing paths via automatic default gateway
WiFi (for GWR402HSW models)
WiFi interface with two modes supported – Access point and Station
IP forwarding
IP, TCP, UDP packets from WAN to LAN.
DMZ support
DMZ host is a host on the internal network that has all ports exposed, except those ports otherwise forwarded.
SNMP v1,2c
Simple Network Management Protocol is used in network management systems to monitor network–attached devices for conditions that warrant administrative attention.
NTP(RFC1305)
The Network Time Protocol is a protocol for synchronizing the clocks of router.

Specifies how many seconds to wait before re–initiating the link after it terminates. The holdoff period is not applied if the link was terminated because it was idle.
LCP–Echo–Failure
If this option is given, pppd will presume the peer to be dead if n LCP echo–requests are sent without receiving a valid LCP echo–reply. If this happens, pppd will terminate the connection. This option can be us
ed to enable pppd to terminate after the physical
connection has been broken (e.g., the modem has hung up) in situations where no hardware modem control lines are available.
LCP–Echo–Interval
If this option is given, pppd will send an LCP echo–request frame to the peer every n seconds. Normally the peer should respond to the echo–request by sending an echo– reply. This option can be used with the lcp–echo–failure option to detect that the peer is no longer connected.

Settings – Routing
The static routing function determines the path that data follows over your network before and after it
passes through the GWR-HS Router. You can use static routing to allow different IP domain users to access the Internet through the GWR-HS Router. Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use dynamic routing because it enables the GWR-HS Router to automatically adjust to physical changes in the network’s layout.
The GWR-HS Router is a fully functional router with static routing capability. Figure 20 shows screenshot of
Routing page.
Figure 20 – Routing configuration page
Use this menu to setup all routing parameters. Administrator can perform following operations:
• Create/Edit/Remove routes (including default route),
• Port translation – Reroute TCP and UPD packets to desired destination inside the network.
Routing Settings
Label Description
Routing Table
Enable This check box allows you to activate/deactivate this static route.
Dest Network
This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.
Netmask This parameter specifies the IP netmask address of the final destination.
Gateway
This is the IP address of the gateway. The gateway is a router or switch (next hope) on the same network segment as the device’s LAN or WAN port. The gateway helps forward packets to their final destinations. For every routing rule enter the IP address of the gateway. Please notice that ppp0 interface has only one default gateway (provided by Mobile operator) and because of that that there is no option for gateway when you choose ppp0 interface.
Geneko GWR High Speed Router Series
34
Metric
Metric represents the “cost” of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.
Interface
Interface represents the “exit” of transmission for routing purposes. In this case br0 represents LAN interface, eth2 wireless interface and ppp0 represents GSM/UMTS mobile interface of the GWR-HS Router.
TCP/UDP Traffic forwarding
Enable This check box allows you to activate/deactivate this static port translation.
Protocol Choose between TCP and UDP protocol.
Interface
Select interface where portforwarding is done. Portforwarding from outside (WAN) interface to inside (LAN) interface is done on PPP, and in reverse direction on br0 interface.
Destination IP This field specifies IP address of the incoming traffic.
Destination Netmask This field specifies netmask for the previous address.
Destination Port This is the TCP/UDP port of application.
Forward to IP
This filed specifies IP address where packets should be forwarded.

Port translation
For incoming data, the GWR-HS Router forwards IP traffic destined for a specific port, port range or
GRE/IPsec protocol from the cellular interface to a private IP address on the Ethernet “side” of the GWR-HS Router.
Geneko GWR High Speed Router Series
35
Settings – Dynamic Routing Protocol
Dynamic routing performs the same function as static routing except it is more robust. Static routing
allows routing tables in specific routers to be set up in a static manner so network routes for packets are set. If a router on the route goes down the destination may become unreachable. Dynamic routing allows routing tables in routers to change as the possible routes change.
Routing Information Protocol (RIP)
The Routing Information Protocol (RIP) is a dynamic routing protocol used in local and wide area networks.
As such it is classified as an interior gateway protocol (IGP) using the distance–vector routing algorithm. The Routing Information Protocol provides great network stability, guaranteeing that if one network connection goes down the network can quickly adapt to send packets through another connection.

telnet 192.168.1.1 2602 // telnet to eth0 at TCP port 2602///
To enable RIP, use the following commands beginning in global configuration mode:
router# router rip
To associates a network with a RIP routing process, use following commans:
router# network [A.B.C.D/Mask]
By default, the GWR-HS Router receives RIP version 1 and version 2 packets. You can configure the GWR-HS
Router to receive an send only version 1. Alternatively, you can configure the GWR-HS Router to receive and send only version 2 packets. To configure GWR-HS Router to send and receive packets from only one version, use the following command:
router# rip version [1|2] // Same as other router //
Enable route redistribution:
router# redistribute kernel // Redistribute routes defined on WEB interface // router# redistribute static // Redistribute routes defined locally in RIP configuration // router# redistribute connected // Redistribute directly connected routes //
Disable RIP update (optional):

Settings – VPN Settings
Virtual private network (VPN) is a communications network tunneled through another network and
dedicated to a specific network. One common application of VPN is secure communication through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with strong security features.
A VPN may have best–effort performance, or may have a defined Service Level Agreement (SLA) between
the VPN customer and the VPN service provider. Generally, a VPN has a topology more complex than point–to– point. The distinguishing characteristics of VPNs are not security or performance, but that they overlay other network(s) to provide a certain functionality that is meaningful to a user community.
Generic Routing Encapsulation (GRE)
Originally developed by Cisco, generic routing encapsulation (GRE) is now a standard, defined in RFC 1701,
RFC 1702, and RFC 2784. GRE is a tunneling protocol used to transport packets from one network through another network.
If this sounds like a virtual private network (VPN) to you, that’s because it theoretically is: Technically, a GRE
tunnel is a type of a VPN — but it isn’t a secure tunneling method. However, you can encrypt GRE with an encryption protocol such as IPSec to form a secure VPN. In fact, the point–to–point tunneling protocol (PPTP) actually uses GRE to create VPN tunnels. For example, if you configure Microsoft VPN tunnels, by default, you use PPTP, which uses GRE.
Solution where you can use GRE protocol:
• You need to encrypt multicast traffic. GRE tunnels can carry multicast packets — just like real network
interfaces — as opposed to using IPSec by itself, which can’t encrypt multicast traffic. Some examples of multicast traffic are OSPF, EIGRP. Also, a number of video, VoIP, and streaming music applications use multicast.
• You have a protocol that isn’t routable, such as NetBIOS or non–IP traffic over an IP network. You could use
GRE to tunnel IPX/AppleTalk through an IP network.
• You need to connect two similar networks connected by a different network with different IP addressing.
Click VPN Settings Tab, to open the VPN configuration screen. In the Figure 23 you can see screenshot of
GRE Tab configuration menu.

IPSec Setup
In order to establish an encrypted tunnel, the two ends of an IPSec tunnel must agree on the methods of encryption, decryption and authentication. This is done by sharing a key to the encryption code. For key management, the Router uses only IKE with Preshared Key mode.
Key Exchange mode
IKE with Preshared Key
IKE is an Internet Key Exchange protocol used to negotiate key material for Security Association (SA). IKE uses the Preshared Key to authenticate the remote IKE peer. Both ends of IPSec tunnel must use the same mode of key management.
Mode One of following IPSec modes can be choosed: MAIN or AGGRESSIVE
Phase 1 DH Group
Phase 1 is used to create the SA. DH (Diffie–Hellman) is a key exchange protocol used during Phase 1 of the authentication process to establish pre–shared keys. There are three groups of different prime key lengths. Group 1 is 768 bits, Group 2 is 1024 bits and Group 5 is 1536 bits long. If network speed is preferred, select Group 1. If network security is preferred, select Group 5.
Phase 1 Encryption
Select a method of encryption: DES (56–bit), 3DES (168–bit) or AES–128 (128–bit). The method determines the length of the key used to encrypt or decrypt ESP packets. AES– 128 is recommended because it is the most secure. Make sure both ends of the IPSec tunnel use the same encryption method.
Phase 1 Authentication
Select a method of authentication: MD5 or SHA1. The authentication method determines how the ESP packets are validated. MD5 is a one–way hashing algorithm
Geneko GWR High Speed Router Series
44
that produces a 128–bit digest. SHA1 is a one–way hashing algorithm that produces a 160–bit digest. SHA1 is recommended because it is more secure. Make sure both ends of the IPSec tunnel use the same authentication method.
Phase 1 SA Life Time
Configure the length of time IPSec tunnel is active in Phase 1. The default value is 28800 seconds. Both ends of the IPSec tunnel must use the same Phase 1 SA Life Time setting.
Perfect Forward Secrecy
If the Perfect Forward Secrecy (PFS) feature is enabled, IKE Phase 2 negotiation will
generate new key material for IP traffic encryption and authentication, so hackers using
brute force to break encryption keys will not be able to obtain future IPSec keys. Both ends of the IPSec tunnel must enable this option in order to use the function.
Phase 2 DH Group
If the Perfect Forward Secrecy feature is disabled, then no new keys will be generated, so you do not need to set the Phase 2 DH Group. There are three groups of different prime key lengths. Group 1 is 768 bits, Group 2 is 1024 bits, and Group 5 is 1536 bits long. If network speed is preferred, select Group 1. If network security is preferred, select Group 5. You do not have to use the same DH Group that you used for Phase 1, but both ends of the IPSec tunnel must use the same Phase 2 DH Group.
Phase 2 Encryption
Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions. Select a method of encryption: NULL, DES (56–bit), 3DES (168–bit) or AES–128 (128–bit). It determines the length of the key used to encrypt or decrypt ESP packets. AES–128 is recommended because it is the most secure. Both ends of the IPSec tunnel must use the same Phase 2 Encryption setting.
NOTE: If you select a NULL method of encryption, the next Phase 2 Authentication method cannot be NULL and vice versa.
Phase 2 Authentication
Select a method of authentication: NULL, MD5 or SHA1. The authentication method determines how the ESP packets are validated. MD5 is a one–way hashing algorithm that produces a 128–bit digest. SHA1 is a one–way hashing algorithm that produces a 160–bit digest. SHA1 is recommended because it is more secure. Bo
th ends of the IPSec
tunnel must use the same Phase 2 Authentication setting.
NOTE: If you select a NULL method of authentication, the previous Phase 2 Encryption method cannot be NULL.
Phase 2 SA Life Time
Configure the length of time an IPSec tunnel is active in Phase 2. The default is 3600 seconds. Both ends of the IPSec tunnel must use the same Phase 2 SA Life Time setting.
Preshared Key
This specifies the pre–shared key used to authenticate the remote IKE peer. Enter a key of keyboard and hexadecimal characters, e.g., Ay_%4222 or 345fa929b8c3e. This field allows a maximum of 1023 characters and/or hexadecimal values. Both ends of the IPSec tunnel must use the same Preshared Key.
NOTE: It is strongly recommended that you periodically change the Preshared Key to maximize security of the IPSec tunnels.
Enable IKE failover Enable IKE failover option which try periodically to •eestablish security association.
IKE SA retry Number of IKE retries, before failover.
Restart PPP After IKE SA Retry Exceeds Specified Limit
With this option enabled PPP connection is restarted when IKE SA retry reaches defined
number of failed attempts. After restart SIM1 is used for connection.
Enable tunnel failover
Enable tunnel failover. If there is more than one tunnel defined, this option will failover to other tunnel in case that selected one fails to established connection.
Ping IP or Hostname
IP address/Hostname at remote side of tunnel which will be pinged in order to determine current state.
Ping interval Specify time period in seconds between two ping.
Packet size Specify packet size for ping message.
Geneko GWR High Speed Router Series
45
Advanced Ping Interval Time interval between advanced ping packets.
Advanced Ping Wait For A Response
Advanced ping proofing timeout.
Maximum number of failed packets
Set percentage of failed packets until failover action is performed.
Compress (IP Payload Compression Protocol (IP Comp))
IP Payload Compression is a protocol that reduces the size of IP datagram. Select this option if you want the Router to propose compression when it initiates a connection.
Dead Peer Detection (DPD)
When DPD is enabled, the Router will send periodic HELLO/ACK messages to check the status of the IPSec tunnel (this feature can be used only when both peers or IPSec devices of the IPSec tunnel use the DPD mechanism). Once a dead peer has been detected, the Router will disconnect the tunnel so the connection can be re– established. Specify the interval between HELLO/ACK messages (how often you want the messages to be sent). The default interval is 20 seconds.
NAT Traversal
Both the IPSec initiator and responder must support the mechanism for detecting the NAT router in the path and changing to a new port, as defined in RFC 3947.
NOTE: NAT–T function is enabled by default and cannot be disabled. The default interval for keep–alive packets is 20 seconds.
Send initial contact
The initial–contact status message may be used when one side wishes to inform the other that this is the first SA being established with the remote system. The receiver of this Notification Message might then elect to delete any existing SA's it has for the sending system under the assumption that the sending system has rebooted and no longer has access to the original SA's and their associated keying material.
NOTE: Send initial contact function is enabled by default and cannot be disabled.

OpenVPN
OpenVPN site to site allows connecting two remote networks via point–to–point encrypted tunnel. OpenVPN implementation offers a cost–effective simply configurable alternative to other VPN technologies. OpenVPN allows peers to authenticate each other using a pre–shared secret key, certificates, or username/password. When used in a multiclient–server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features. The server and client have almost the same configuration. The difference in the client configuration is the remote endpoint IP or hostname field. Also the client can set up the keepalive settings. For successful tunnel creation a static key must be generated on one side and the same key must be uploaded on the opposite side.

Encryption Cipher
Encrypt packets with cipher algorithm. The default is BF-
CBC, an abbreviation for
Blowfish in Cipher Block Chaining mode. Blowf
ish has the advantages of being fast,
very secure, and allowing key sizes of up to 448 bits. Blowfish is designed to be used
in situations where keys are changed infrequently. OpenVPN supports the CBC
cipher mode.
Hash Algorithm
Authenticate packets with
HMAC using message digest algorithm. The default is
SHA1. HMAC is a commonly used message authentication algorithm (MAC) that uses
a data string, a secure hash algorithm, and a key, to produce a digital signature.
OpenVPN's usage of HMAC is to first encryp
t a packet, then HMAC the resulting
ciphertext. In TLS mode, the HMAC key is dynamically generated and shared
between peers via the TLS control channel. If OpenVPN receives a packet with a bad
HMAC it will drop the packet. HMAC usually adds 16 or 20 bytes
per packet. Set none
to disable authentication.

Layer2 Tunneling Protocol (L2TP)
The GWR-HS router can be used as a L2TP peer. L2TP is suitable for Layer-2 tunneling. Static tunnels are useful to establish network links across IP networks when the tunnels are fixed. L2TP tunnels can carry data of more than one session. Each session is identified by a session id and its parent tunnel's tunnel id. A tunnel must be created before a session can be created in the tunnel.

Management – Logs
Syslog is a standard for forwarding log messages in an IP network. The term "syslog" is often used for both the actual syslog protocol, as well as the application or library sending syslog messages.
Syslog is a client/server protocol: the syslog sender sends a small (less than 1KB) textual message to the syslog receiver. Syslog is typically used for computer system management and security auditing. While it has a number of shortcomings, syslog is supported by a wide variety of devices and receivers across multiple platforms. Because of this, syslog can be used to integrate log data from many different types of systems into a central repository.

GRE Tunnel configuration between GWR-HS Router and third party router
GRE tunnel is a type of a VPN tunnels, but it isn't a secure tunneling method. However, you can encrypt
GRE packets with an encryption protocol such as IPSec to form a secure VPN.
On the diagram below (Figure 67) is illustrated simple network with two sites. Idea is to create GRE tunnel
for LAN to LAN (site to site) connectivity.
Figure 67 – GRE tunnel between Cisco router and GWR-HS Router
GRE tunnel is created between Cisco router with GRE functionality on the HQ Site and the GWR-HS Router on the Remote Network. In this example, it is necessary for both routers to create tunnel interface (virtual interface). This new tunnel interface is its own network. To each of the routers, it appears that it has two paths to the remote physical interface and the tunnel interface (running through the tunnel). This tunnel could then transmit unroutable traffic such as NetBIOS or AppleTalk.
The GWR-HS Router uses Network Address Translation (NAT) where only the mobile IP address is visible to the outside. All outgoing traffic uses the GWR-HS Router WAN/VPN mobile IP address. HQ Cisco router acts like gateway to remote network for user in corporate LAN. It also performs function of GRE server for termination of GRE tunnel. The GWR-HS Router act like default gateway for Remote Network and GRE server for tunnel.
1. HQ router requirements:
•
HQ router require static IP WAN address,
•
Router or VPN appliance has to support GRE protocol,
•
Tunnel peer address will be the GWR-HS Router WAN's mobile IP address. For this reason, a static mobile IP address is preferred on the GWR-HS Router WAN (GPRS) side,
•
Remote Subnet is remote LAN network address and Remote Subnet Mask is subnet of remote LAN.

2. The GWR-HS Router requirements:
•
Static IP WAN address,
•
Peer Tunnel Address will be the HQ router WAN IP address (static IP address),
•
Remote Subnet is HQ LAN IP address and Remote Subnet Mask is subnet mask of HQ LAN.
GSM/UMTS APN Type: For GSM/UMTS networks GWR-HS Router connections may require a Custom APN. A Custom APN allows for various IP addressing options, particularly static IP addresses, which are needed for most VPN connections. A custom APN should also support mobile terminated data that may be required in most site–to– site VPNs.
