I know that he allows ICMP, and he can successfully ping other systems, but traceroute simply stops at the router. However he can successfully do a traceroute from a Windows box.

Windows tracert differs from *nix traceroute.

Windows uses ICMP packets. Unix variants use a UDP packet with a port set to a high number (typically 33435).

Check to see what UDP ports are allowed in and out. Actually, the default port is UDP 33434. I had him open that port up in his router. I didn't realize that Windows traceroute uses ICMP. In any case, I'll have him take a look with ethereal. --

Hello, This most likely is a bug in the router's firmware. I had a similar problems with Linux traceroute loosing packets when going through my Linksys router. After contacting Linksys tech support, they emailed me a beta release firmware that fixed the problem. ~James
