I have failover configured on 2 cisco 4331 vpn routers, the primary router and the secondary router are configured with different internet circuits. When testing the fail over, the secondary router takes over with no problem and everything can be accessed. So the failover works correctly in this sense. But.. there were a couple of issues accessing certain applications at site, now this seems to be resolved after taking a look at the ACL.
But now the secondary vpn router cannot be accessed via SSH on its loopback/management address.
The primary can be accessed without issue and both tunnels are up. As a test we disabled the interface of the secondary router and we can access it via SSH. But as soon as we enabled the interface again and both tunnels are up, we cannot access the secondary via its loopback again. Any ideas of what could be causing this issue? I assume something to do with routing? Or i could possibly be on the wrong track.
