Hi,


Are you wishing to configure the Active/Standby via the Management port or monitor this interface as part of the failover?  If the latter then it's not recommended, the firewalls will changes roles should these interfaces change state, which you really don't want happening.  Let me know how you get on on the link provided in the other post, I have configure 2 ASA 5520 in Active/Standby mode and they work just great

Hi,


Actually i dont have any more interface to configure failover , thats why i have to use managment interface to configure failover, my question is this can it work when firewall is in routed mode with single context mode,i want to configure stateful lan based active/standby failover.


From the above document my understanding says tht we can configure it, and actually i had configured it but when my active firewall goes down standby will take over but my application which are running in intranet and internet zones are not working.

The configuration of primary firewall replicates to the secondary when it goes down and i also confirmed these and and all the interfaces is up but my websites which are in dmz and inside zones are not working when primary firewall goes down.

Can you post your configure for your interfaces and do a "sh failover" and post here please.

Your interfaces don't seem to have standby IP's, please post "sh run | i monitor" and post your ASA interfaces to see how you have configured them.
