Re: [TCLUG:4495] Cisco 675 Router

You'll have to use ipmasquerading to accomplish this.  What you do is set up
a linux ipmasqing/firewalling box with 2 NICs in it.  Plug the yellow crossover
cable into the NIC that you have configured with the IP that you ISP gives you
and run a cable to your hub from the other NIC (this NIC serves as the gateway
for your network, btw).  Then just read the ipmasquerading howto and put some 
ipfwadm commands (for 2.0.3x kernels) or ipchain commands (for 2.2.x kernels)
and you're all set.  Granted this is a VERY basic explanation and I had a
helluva time getting it setup under RedHat (I don't know much about the config
scripts), but it only took about 10 mins under Slackware3.6.

Good luck...
