I have 2 ASA 5510's in A/P failover using the Management port.
I have failover setup for ISP failover
Int 0/0 (Outside) Primary
Int 0/1 (Inside)
Int 0/2 (Backup_DSL) Backup
Fail over is working perfectly in Int 0/0 goes down Int 0/2 comes up and I can access the internet but for some reason I am unable to bring up a VPN on Int 0/2 is it disabled by design on the 5510 (IOS 7.2)?
Tested for 4 hours with all possible options and can conclude there is some block on the interface stopping VPN's coming up.
Can anyone confirm???
