No, the router (external I/F) is connected to the carrier gateway (these are talking to each other ising 172.x.y.z). Leave these as they are and connect nothing else to them. Assign public IP number 1 as a second address to the router's internal interface (alongside 192.168.21.1), and assign public IP number 2 to the machine which is causing all the trouble. That machine is already connected to your internal hub/switch, so therefore it can talk to the router, using public IP number 1 as its default gateway address. Hope this is clear now. Why didn't the user requiring secure access to the system just use a VPN? Antony. -- My New Year's resolution is not to make any resolutions I can't keep. I'm wondering whether I've failed already.
