Interface failover on single ASA

Unanswered Question
Mar 10th, 2008

We have 1 ASA firewall and 2 LAN switches. Can it be configured that the ASA connects in to both switches and in the event of switch failure connection to the firewall is still possible?


We have 4 interfaces on the ASA.


thanks

You cannot do this as the ASA will not allow to have the same IP subnet on 2 of its interfaces


If you need redundancy, then you require one more ASA box which can be configured for failover

Mike,


That requires V8 code, which is still very early. I don't know that i'd be using it on a production system just yet.
