The first is that your default route should be through eth0 with the gateway your ISP gives you. (12.73.1.<something>). If you want the machines on the 192.168.1.0 network to be able to access the Internet through this box, you will also have to set up some NAT iptable rules. Take a look at the firewall packages and see what on is easy for you to understand - NAT is normally set up as part of the firewall. You really need to read one of the networking and firewall HOWTOs so that you understand what you are doing, or get someone locally to set this up for you. Without a basic understanding of how networking works, it is too easy to make mistakes or misunderstand instructions when using advice from a mailing list.
