Read the RFC's, or /etc/hosts ... net 10.a.b.c is reserved, and CANNOT be routed onto the internet. A lot of ISP's give host unreachable for the reserved nets, e.g.: traceroute to 172.16.1.1 (172.16.1.1), 30 hops max, 40 byte packets 1 finch-141.access.demon.net (194.159.253.141) 173.382 ms 179.674 ms 158.114 ms 2 trude-access.router.demon.net (194.159.253.99) 179.877 ms 192.276 ms 198.179 ms 3 trude-access.router.demon.net (194.159.253.99) 180.063 ms !H 192.213 ms !H 198.221 ms !H You are facing other problems. Your ISP won't have a route saying to send net 10 destined packets to your gateway. You probably also don't have packet forwarding enabled in your kernel. Solution: use proxy servers on your gateway box, don't try and route net 10. Alternatively, get more IP addresses allocated to you by your ISP.
