Hello, I am working on adding a debian slink linux system as a fire wall to my existing company network. When finished, we will have an ISDN router connected to the linux firewall machine and a separate network card connecting the internal network to the linux system.
The mail server will be inside of the firewall and needs to receive SMTP connections through the firewall. My question is how is this done? I will have fixed IP addresses for the router and linux system, but the mailserver will have an internal 192.180... IP address. Can this be done? If so, where should I be looking for information as far as setting up the linux system goes? Thanks, Doug
