ASA with backup link

Unanswered Question
Jan 12th, 2010

Hi All,

we have ASA with two ISP and configured SLA for link redundancy. we've applied port mapping (PAT) in backup link for inbound traffic coming to our web and FTP server. so when traffic comes to ASA from backup link and hits the internal server, how internal server return back the traffic in this session? by backup link or primary link? we want returning traffic going through backup link, but static default route in ASA point to primary link. I am not sure about ASA behavior in this situation.

appreciate any suggestion.

Alex

The ASA does not support that behavior. It does not support policy based routing or dual ISPs.

What you can do is use a router before or after the ASA to do PBR.
