I woder if using ASA or PIX, can I set up the outside interface with 1 IP then for outgoing (on the same outside interface) with another IP address. For example: outside IP 22.214.171.124 then somehow for outgoing(return traffic if you will) the IP address to be visible is 126.96.36.199 (partner requirement, don't ask :) ).
Doing this on Linux iptable already and now is thinking to change it out to something else,i.e. ASA or PIX.
Thank you for your hep.
