I have a box with a 3com nic and a Sangoma WAN card running as a mail server andoffice router. Is there a way, when I talk to the outside world across my WAN card, to make it use the ip address of my ethernet card. In other words, when I telnet, ssh, ftp to a box on the outside world, I want it to show up as a connection from mail.mynetwork.com (my ethernet address) and not host_on.framerelaycloud.provider.com (my wan address).
