We do something like this with a combination of Apache and a Cisco router. On the Ethernet interface on the Cisco: ip policy route-map SUSPENDED access-list 192 permit tcp 192.168.0.0 0.0.0.255 any eq www route-map SUSPENDED permit 10 match ip address 192 set interface FastEthernet0/0 set ip next-hop 65.165.120.180 ! What this does is forward all packets with a source address anywhere in 192.168.0.0/24 and connecting to port 80 to 65.165.120.180. The next trick is getting the Unix box to accept the packets... A little packet rewriting in IPFW: rack0# ipfw show 00100 8964 881988 fwd 65.165.120.180 tcp from 192.168.0.0/24 to any 80 Any packets that arrive with a source address in the 192.168.0.0/24 get redirected to this box. Apache has a custom 404 error page. No matter what web page a customer with a 192.168.0.0/24 address requests they get the custom 404 error page ("Pay up bum - your account is toast").
