Tell me please how to configure Tunnel Backup with dynamic IP on the Cisco RV325 router.
There are 2 routers Cisco RV325, Firmware v1.3.2.02, between them configured Gateway to gateway tunnel.
The first router (R1) has 2 ISP providers which are connected to two WAN ports. The first WAN port has static IP, and on the second WAN - dynamic IP. Between them is configured Smart Link Backup and the first WAN is Primary WAN.
On the second router (R2), only 1 ISP with a static IP.
If R1 switches from ISP 1 to ISP 2, the tunnel with R2 disappears.
Help me plese, how to configure Tunnel Backup on R2 when R1 uses WAN2 with dynamic IP.
As I can see, there is no option to configure it on RV325.
Thank you.
