Setup a Proxy or Ipmasq

I have two ethernet cards. One connected to the cable modem the other to my internal network. I want all the boxes on the internal network to be able to use netscape, real player etc. What is the best way to go about it and how is it done? -tom-

adding a second ethernet card

I'm running slink. My eth0 is an ne2000 and works fine. I want to add a second ne2000. I've tried editing the lilo.conf file with: append=ether 12,0x300,eth1, then runing lilo and then rebooting but no luck. What is the process? thanks, -tom-

has anyone successsfully gotten dhcp to run on a box with 2 ethernet cards? If so, then what did you use and how did you setup the dhcpd.conf file? -tom-
