Introduction

LRT214/LRT224

Linksys’s VPN Routers for Small Business, LRT214 Gigabit VPN Router and LRT224 Dual WAN Gigabit VPN Router, support site-to-site VPN, which allows branch offices to connect with the central office, and client-to-site VPN, which allows employees to securely connect back to their offices while they are away. The dual-WAN model supports WAN Failover, which allows a business to continue its network operation when one of its WAN connections to the Internet fails. With dual-WAN load balancing, the dual-WAN model can aggregate the bandwidths of both WAN connections to achieve a higher Internet bandwidth than what a single WAN connection can provide.

Employees increasingly demand remote access to enterprise IT resources through their mobile devices such as smartphones and tablets. LRT214/LRT224 support OpenVPN server, which allows OpenVPN clients running on employees’ laptops, smartphones, and tablets to connect to the offices using two-factor authentication. Two-factor authentication typically requires pre-installed certificates as part of the authentication of an OpenVPN connection, in addition to username/password, for additional security.

Introduction

Like other Linksys routers, the products have an intuitive Web administrative interface that allows small business owners to deploy and manage the routers without professional IT staff onsite. The operational health of the products can be monitored through system logs and email alerts. Standard MIBs are supported, which allows the products to be monitored by a SNMP-based network management system.

The products come with an integrated firewall that supports URL filtering and access rules that allow administrators to further regulate the traffic within the business network based on the services (i.e. TCP/UDP ports) and source/ destination IP addresses.

LRT214/LRT224 routers support 802.1q, which provides separation between resources in different SSIDs/VLANs. This allows them to work with modern wireless access points that support multiple SSIDs.. With inter-VLAN routing, the products allow specified traffic to traverse between VLANs. The products support dual stack IPv4 and IPv6, as well as transition technologies such as 6to4.

Linksys

Hardware Installation

• DMZ: Use the DMZ (Demilitarized Zone) port to connect to a DMZ host,

such as a Web server or mail server. Inbound traffic can access the DMZ host without exposing your intranet.

• WAN/DMZ (LRT224):LRT224 Dual WAN Gigabit VPN Router comes with

a port you can configure as a second WAN port or DMZ port based on your network requirements.

DMZ Setting

For some network environments, an independent configurable DMZ port may be required to set up externally connected servers such as WEB and Mail servers. Therefore, the device supports a set of independent configurable DMZ ports for users to set up connections for servers with real IP addresses. The DMZ ports act as bridges between the Internet and LANs.

Check Enable DMZ box and click the edit icon to configure DMZ port.

The DMZ configuration can be classified by subnet and range.

Subnet:

If the DMZ and WAN are located in different subnets:

If the ISP issued useable public IP addresses: 220.243.230.1-14 with Mask

255.255.255.240, users have to separate the 14 IP addresses into two groups:

220.243.230.1-6 with Mask 255.255.255.248, and 220.243.230.9-14 with Mask

255.255.255.248 and then set the device and the gateway in the same group with the other group in the DMZ.

Range:

If the DMZ and WAN are within same subnet:

IPRange:Input the IP range located at the DMZ port.

Setting up a DMZ host will allow one host in the LAN to be exposed to the Internet to use services such as Internet gaming and video conferencing. Access to the DMZ host from the Internet can be restricted by using firewall access rules. Use the Configuration > Setup > DMZ Host page.

Enter the LAN IP address of the server that you want to use as a DMZ host.

Port Forwarding and Port Triggering

You can set up a port forwarding virtual host to allow public access to servers connected to the LAN ports. Port Forwarding opens a specified port or a port range for a service, such as FTP, WWW, and mail, etc. Port Triggering opens a port range for services that use alternate ports to communicate between the server and LAN host. Use the Configuration > Setup > Forwarding page to configure.

Setup

Port Range Forwarding

Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests to your network, the router can forward those requests to computers that are equipped to handle the requests. If, for example, you set the port number 80 (HTTP) to be forwarded to IP address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2.

To set up other services input the server TCP or UDP port number and the virtual host IP addresses.

Service Management.

One-to-One NAT

If your ISP issued more than one actual IP (such as eight ADSL static IP addresses or more), you can map the remaining real IP addresses to the intranet devices with virtual IP addresses.

You can also map a private IP address range to a public IP address range of equal length (for example, five private addresses and five public addresses). The first virtual address will be mapped to the first external address.

Use the Configuration > Setup > One-to-One NAT page to enable One-to-One NAT (Network Address Translation).
