I have a server based on RH 9.0 It has two network cards, one is Ethernet , the other is Token Ring (Ethernet distance limitation required Token Ring to connect two separate networks). The server's eth0 is 192.168.2.9, tr0 is 172.25.1.9. This server replaces a RH 7.3 machine which was configured with the same NIC combinations at 192.168.2.12 and 172.25.1.12. The 7.3 machine routed flawlessly. Oh on the other end of the Token Ring is an old RH 7.0 machine also with tr0 at 172.25.1.19 and eth0 at 192.168.5.3. There are several devices on the 192.168.5 network users on the 192.168.2 network need to access. Both the 7.3 and 9.0 machines are NOT running IP Chains or IP Tables. I mv'd the /etc/rc.d/rc5.d/S08ipchains and S08iptables to s08... so they don't start. On both the .2 and .5 Ethernets are Linksys BEFSR 4.1 cable/dsl routers. Each one has static routes defined. The 5 router has a static route saying to get to the 2 ethernet to route traffic to 192.168.5.3. This 7.0 machine has static routes for the .2 network to point to 172.25.1.12. Again all worked fine with the 7.3 machine as the router. When I change from 172.25.1.12 to 172.25.1.9 traffic on the 5 Ethernet gets as far as the RH 9 server but can't get onto the 2 network. Devices on the 5 network can ping the Ethernet interface of the RH9 machine but nothing else on the 2 Ethernet. I've reviewed the configs on both the 7.3 and 9.0 to the best of my abilities but can't figure out why the 9.0 machine won't forward packets onto the 2 network from 5 or from the 2 network onto the 172.25 Token Ring.
Suggestions?
TIA
