Setting up IPsec site-to-site VPN Failover (PSK)  

VPN Router A Configuration  

•

Note: IPsec VPN failover is only supported on firmware 1.0.0.33 or above. This  

configuration will only work when multiple WAN configuration is set to WAN1  

(Failover to WAN2), WAN2 (Failover to WAN1), Load Balance (weight cannot be  

set to 50%:50%).  

Network > VPN > IPsec  

VPN failover configuration allows you to add redundancy/fault tolerance to your IPsec  

VPN tunnel connectivity.  

To configure and IPsec site-to-site VPN tunnel failover with pre-shared key (PSK)  

between two routers:  

1. Log into your router management page (see “Access your router management page”  

on page 6).  

•

Ensure that your router is connected to the Internet and computers and  

devices are able to access the Internet through the WAN1 and WAN2 interfaces  

on your router and make note of the WAN1 and WAN2 IP addresses assigned  

to both routers under the Status > Overview page. In this example, we will  

assume the following static IP WAN info. and LAN IP settings below.  

2. Click on Security, click Firewall, and click the General Settings tab.  

3. Check the Enable under WAN Ping Respond and click Apply to save and commit the  

configuration changes.  

Example:  

VPN Router A WAN1 (Internet) IP Address: 10.10.10.85 / 255.255.255.192  

VPN Router A WAN2 (Internet) IP Address: 10.10.10.130 / 255.255.255.192  

VPN Router B WAN1 (Internet) IP Address: 172.16.0.1 / 255.255.255.192  

VPN Router B WAN1 (Internet) IP Address: 172.16.0.62 / 255.255.255.192  

•

Make sure the LAN IP network on each VPN router is a different IP subnet.  

Note: Changing the LAN IP address of your router will change the LAN IP  

network of your router.  

4. Click on Multi-WAN/QoS and click on Multi WAN.  

Example:  

VPN Router A LAN IP Settings: 192.168.200.1 / 255.255.255.0  

VPN Router B LAN IP Settings: 192.168.210.1 / 255.255.255.0  

5. Under the Link Tracking section, check Enable Tracking on both WAN1 and WAN2,  

and enter an IP address or IP addresses on the Internet to check for connectivity and
