how to drop all traffic except internet and specific local IP address
I will like to allow traffic to internet from one station, but not to the local network (lan). I would like if posible to allow access from that station to 3 diferent servers on the local network: DHCP, Proxy cache and UNTANGLE. Any Idea?
The internet access is Client - LINUX BOX - switch - CISCO ROUTER - LINUX PROXY - UNTANGLE SERVER - ISP ROUTER TO INTERNET
