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?



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
