RE: RH 8.0 - 2 NICS and routing between 2 subnets

IPTables is not running yet as I want to get routing straight before I start iptables. Using route -add I have added net work A go out eth0 and network b go out eth1 and all is fine when pinging from the box itself - I can ping both sides - any host from network A or B can be reached from the box. I drop back to a host on a hub behind network A and I can ping both interfaces on the firewall - netstat -rn on the host confirms proper routing. Same from a host inside network B - I just cannot ping across. Since the route -show on the future firewall box has the proper routes how do I get them to route across? Do I need to run gated like I'm used to doing on the HPUX boxes - I thought simple 2 ip domain with static routes should do the trick? No dynamic routing protocols going on, just 2 simple subnets. Thanks for any help Mike Pacheco
RE: RH 8.0 - 2 NICS and routing between 2 subnets
To clarify, you have a future firewall connected to network A, and the single RH8 box connected also to network A and network B. What is the future firewall?

RH 8.0 - 2 NICS and routing between 2 subnets
Hi All, I've got a single RH 8.0 box I'm setting up as a firewall, 2 nics in two separate IP domains. IPTables is not running yet as I want to get routing straight before I start iptables. Using route -add I have added net work "A" go out eth0 and network "b" go out eth1 and all is fine when pinging from the box itself - I can ping both sides - any host from network "A" or "B" can be reached from the box. I drop back to a host on a hub behind network "A" and I can ping both interfaces on the firewall - netstat -rn on the host confirms proper routing. Same from a host inside network "B" - I just cannot ping across. Since the route -show on the future firewall box has the proper routes how do I get them to route across?
