While in the ever continuing process of setting up my home netwok, I'd like to have a firewall/mail server outside of the internal network. (I.E. connected BETWEEN the router and the cable modem. "double nat") I'm a bit anal about computer security. Any ideas how this can be accomplished? Any suggestions would be welcome. N.B. Using a PII 450 with 2 nic's running Fedora Core 2 (stripped) as the existing firewall INSIDE the LAN but I'd like to move it to the WAN port. Let me know what you think.
