I'm trying to get a router/firewall box up and running with a new Asus p4p800 board, with a 3com gigabit lan. I had little or no trouble installing the drivers for the card, and everything appears fine. I can ping out from the system and all seems well. However when the box is hooked up as a router, no traffic is getting through. I have installed webmin on the system and when it is remotely connected to from a local lan, it is incredibly slow, to the point where some pics are visible on the webmin interface but never do load. Does anybody know if this is a network settings configuration error? Or some issue with the card? I have nothing else to try.

Thanks,

Albert Norman

Hi anorman,

You can check if your kernel is configuried to route packets:

cat /proc/sys/net/ipv4/ip_forward

1 - kernel routes packets
0 - kernel doesn't route packets (echo 1 > /proc/sys/net/ipv4/ip_forward # an try it again)

Do you installed a firewall? Maybe there is an configuration error ...

bye

Hmmmm, thanks Yoss, I hadn't thought of checking that, but the kernel is configured to route packets. Is there somewhere else in a network configuration file where routing should be enabled for the card?

Thanks,
Albert

By the way, I have no firewall configured as of now.

Hi anorman,

maybe there is an configuration error in your network configuration.

Please post your configuration, from the router and the computer which has the router as default gateway.

Use "ifconfig -a" and "netstat -rn" . Try some "ping" and use tcpdump to deteminate where the packets get lost.

regards
Yoss
