The internal routing will be fixed be our internal routers and send to the F5, as the internal serves do not have the F5 as the default gateway.

 

But the SNAT is stripping off the client IP to the servers, as it should do. It would be nice to have a SMTP x-forward. :-) I was reading about this problem for other users and some sugestions was using NAT instead of SNAT. Any sugestion for a new irule or NAT? We need to see the client ip addresses on the servers for security resonds.
