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.

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.

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.

Hardware Installation

Ports

LRT214

In this chapter we are going to introduce hardware interface as well as

physical installation.

LRT224

•WAN: : The WAN ports can be connected with DSL or cable modems,

provided by your internet service provider (ISP).

•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.

NOTE

Dual WAN settings, such as link failover or load balance, will be

disabled when you configure the port as DMZ port.

LAN (1~4):Use the LAN ports to connect devices such as switching hubs,

computers, printer servers, etc., to the local network or intranet.

Placement Tips

•Do not place anything on top of the router. It could be damaged by

excessive weight.

•Do not obstruct heat dissipation holes on the sides of the router.

•Do not expose to direct sunlight or other heat source. Keep area around

router adequately ventilated.

•Place the router on a flat surface.

Wall Mounting Tips

The router has two wall-mount slots on its bottom panel. When mounting the

router on the wall, please ensure that the heat dissipation holes are facing

sideways as shown in the following picture for safety reasons. Linksys is not

responsible for damages incurred by insecure wall-mounting hardware.
