Hi mates,
Our client has a WAN site with dual ISPs connecting to the Central Management Gateway. They want to implement ISP redundancy. In the event of a failover, the WAN site should establish a VPN connection over the secondary ISP to the central gateway. We've configured ISP redundancy using the Smart Console. However, during our failover tests (unplugging the cable or disabling the interface), while routing successfully switches to the second ISP, the VPN seems to encounter issues. The remote site indicates that the VPN is up, but the internal subnet behind the gateway cannot reach the central management internal IPs over the VPN.
Other point is, central gateway is trying to establish VPN with failovered ISP´s IP.
Thnks.
