I'm trying to setup a RedHat 7.2 box on my home network to act as a router between between my token ring Cisco routers (2 2502s) and the rest of my (ethernet and wireless) network. The two subnets are 192.168.1.0/24 (ethernet) and 10.0.3.0/24(token ring). From the RedHat box I'm able to communicate with everything on both subnets. What I want to do now is make the Cisco routers accessable to the rest of the network using static routes.

What I've done so far is setup the routing tables on the RedHat box and a FreeBSD box on the ethernet subnet appropriatly, disabled packet filtering and changed the value of the net.ipv4.ip_forward line in /etc/sysctl.conf to 1. I thought this was all I'd need to do, but at this point, the only host that the FreeBSD box can ping on the token ring subnet is the RedHat box.

Any ideas on what I'm missing? I have a feeling I may have to recompile the kernel or load a kernel module, but I looked around in the kernel parameters, and am not sure what to change if anything.

have you added the default gateway to the routing tables for the freebsd box? 'route add default gw ipaddress .. eh but you probably already have, a good site for this would be the LRP at http://www.linuxrouter.org , will have more info than i do, good luck ..

Thanks neuralfx, I'll check out that website. The FreeBSD box has its default route set as my firewall and the route to the token ring subnet set as the RedHat box's ethernet interface. When I run traceroute I get the first hop as the RedHat box's ethernet interface (which is correct), but nothing after that.

I just figured it out. I needed to include the following line in my /etc/sysconf/network file:

DEFRAG_IPV4=yes
