ASA Active/Stanby Failover - IP addressing

[Cory Peterson]

I am getting ready to setup avtice/standby failover on our ASA 5520's and have run in to an issue.

I currently only have one External IP address available.

My Idea was to use a private/placeholder IP address for the standby external IP Address, will this cause any issues with the failover? I know I won't be able to access the secondary from the outside, but that is not an issue.

Cory in that case you can configure the outside interface without the standby IP. The show failover will show that interface as normal (waiting) since it can't talk to the other interface.

You shouldn't have any issues with that.

Awesome! Thank you for the reply. I will try that out!
