The Model RV082 Router Allows You to Set up a Backup VPN by Simply Allocating a Second

The Model RV082 router allows you to set up a backup VPN by simply allocating a second WAN connection that traverses a different network or network edge (for example, Cable Modem via MSO and DSL). This requires additional IP addresses on the WAN side and configuration of additional backup tunnel parameters on the primary tunnel.

Figure 18 shows two sites with dual WANs. There is only one tunnel to configure between any two sites for this topology, but it is created with one backup WAN on each side.The RV082 allows the redundant WAN connection to be used as an IPSec backup tunnel. If an IPSec connection cannot be established, a backup IPSec VPN connection is then established. This is not load sharing. The backup tunnel becomes active on the failure of the primary tunnel.

Figure 18: Two Sites with Dual WAN Connectivity

To accomplish redundancy on the RVO82 router, configure WAN1 as shown in Figure 19, then use the router configuration GUI to set up the second WAN with its own IP address.

Next, go to the System Management page and specify that the second WAN port is being used as a load balance port.

Once you do this, the WAN port will show up in the System summary and can be selected from the VPN tunnel creation pages.


Warning / Do not create a new, separate tunnel using the backup WAN. Instead, select the Advanced tab for the primary tunnel, and complete the fields in the GUI using the backup IP addresses.

Before saving, select the Advanced tab to access to the GUI to specify this is a tunnel backup, as shown in Figure 22.

Once this is done on both sides of the tunnel and the tunnel is connected, you can check the status at any time from the VPN > Summary page in the GUI. The following figure shows that the Primary tunnel on WAN1 is active.

If you then disconnect WAN1, the VPN > Summary status page will show that the backup tunnel is active.
