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.
