Hello, Can someone help a network newbie with setting up FreeBSD 2.0-R as a gateway? I've compiled gateway support into the kernel with `options GATEWAY', and i'm running `routed -g'. Here's the setup: I have a couple of freebsd machines at home linked with ethernet. One of the machines (machine A) also connects to an ISP via slip. Machine A is to be a gateway between my local ethernet and the internet. machine a: ip# to slip is 204.131.81.86. ip# to ethernet is 204.131.231.1. I have this machine's default route pointing to the ISP's slip address. Packets between this machine and the internet are routed properly. machine b: ethernet's ip is 204.131.231.10. The default route is machine a's ethernet ip#. I can talk fine between this machine and machine a. Both machines are running FreeBSD 2.0-R. Machine A is a pentium-90 with a 3c509, machine B is a DECpc 486/50 with a DEC DE202 ethernet card. Via tcpdump, when I try to ping from machine B to the internet, I can see packets coming into machine A via the ethernet, but I see no packets coming out of machine A's slip interface to the internet. I don't know what to do next... I was assuming that by simply enabling gateway support in kernel and running routed -g would forward packets between the two interfaces in machine A. Obviously I'm mistaken. I'd really appreciate any help, -Ade Barkah
