Cisco VPN w/more than one WAN

Hello everyone.

I have ASA w/more than one WAN. I created a server group for DUO and added the server with the API hostname, DN info, password etc. Also when adding it, it makes you pick an interface. We tested this and everything works when using that interface.

Unfortunately, the 2nd password doesn’t come up when connecting via a different interface. Also we can’t login. Would be nice to be able to VPN when the primary WAN connectivity is down.

I tried putting a second entry with other interfaces but errors that is duplicate.

Any ideas? Thank you.

Anyone able to help shed some light? Can’t imagine I’d be the only one in this situation running into problems.
