I would like to set up a gateway-firewall with this box so I added a 3C905B NIC in this computer. Thus I am using the 3C90x for the two NIC as preconized by 3Com. And then nothing is routed through the two NICs. My public IP is well responding on the 3C59x and my private IP is responding on the other NIC but when I define this box as a gateway for another one nothing passes through. I use manually each time I restart "echo 1 >/proc/sys/net/ipv4/ip_forward it". But it didn''t help me. I put a tcpdump on each interface and I can see that nothing passes through one card to another in any direction... Is there a bug with this 3Com driver module or am I proceeding the wrong way to build a gateway ? I tried the following commands because my intention was originaly to give access from outside to a computer in my LAN : ipchains -s 195.154.93.0 -d 172.16.1.36 -j MASQ -A forward (with and without the -b option) ipchains -s 195.154.93.0 -d 172.16.1.36 -j ACCEPT -A forward (with and without the -b option) and many various rules that I think should have routed packets from outside to inside but I lost two days on it.... I am quiet new in Linux and I may have tried the wrong tools or failed my box setup... Any help would be pleased 8.) Regards Matthieu Fleurmont Keymage
