I have a Cisco Pix 501 firewall currently setup. I'm looking to setup a 2nd subnet so I can put one computer on it. That computer needs to have internet connectivity. I tried to install a Linksys RVS4000 behind the Pix, configured it with a 192.168.2.1 address an have disabled its DHCP server. What else do I need to go to get that one computer behind the RVS to get to the internet?
