Is it possible to implement redundant ISP's with failover firewalls using virtual interfaces and the ISP connetions? I have a 5520 with the standard number of interfaces and want to create virtual interfaces on the outisde interface?

When you say virtual interfaces are you talking about sub interfaces?


These can each be a different vlan and can be monitored for failover etc...

The interface tracking in that version brakes when using a failover pair. The tracking works until failover occurs. Then a reboot of both firewalls is required to fix the tracking.


Bug: CSCsd51407

Dual ISP fails after failover, routing table have stale routes


A new release is coming soon to fix the bug. 7.2(1) is the only version out that supports tracking.


Thanks,

Chad
