You need to either add a static route between them or change their netmasks to at least a /21. Huh? They _must_ be on different subnets. You can't route one subnet across multiple network interfaces. Besides, a router always knows how to route packets between its own directly-attached networks, no additional routes are necessary. The problem here is that a route needs to be added for 192.168.10.0/24 - 192.168.0.100 in the upstream router(s), since the upstream router(s) do not currently know to send any packets destined for 192.168.10.0/24 to 192.168.0.100 for delivery. The upstream router is currently sending these packets to its own default gateway, which is likely even further upstream. IP routers aren't mind-readers, you have to tell them exactly where to send packets, but usually that is very simple. Running a routing protocol (such as RIP) on both the FreeBSD box in question and the upstream router(s) would automatically add the same route for you, but that is unnecessary in such a simple network configuration. -- Chris Dillon - cdillon(at)wolves.k12.mo.us FreeBSD: The fastest, most open, and most stable OS on the planet - Available for IA32, IA64, AMD64, PC98, Alpha, and UltraSPARC architectures - PowerPC, ARM, MIPS, and S/390 under development - http://www.freebsd.org Q: Because it reverses the logical flow of conversation.

Networking problem UPDATED
I have a friend who can not get his FreeBSD 5.2 server to act as a gateway, from the internal network we can ping the external network card, but no further. From the server we can ping the entire world. I had him bring it over and set up my server(FreeBSD 4.8R as the gateway) all my clients can use my FreeBSD server fine, so I do not think the problem is in it, so I now have: ISPMy Server---his Server---laptop My Server to ISP is a dynamic IP (ppp dialup) My server internal network is 192.168.0.1 His server to my server is connected to my servers hub and his server uses ip 192.168.0.100 His server to my laptop is connected with a cross over cable, his server is 192.168.10.1 My Laptop is 192.168.10.42 From the laptop I can ping as far as the external nic on his server (192.168.0.100).
