Traceroute and Linksys routers

A friend of mine who has SuSE 10.1 and a Linksys router (I think an older BEFSR41) is complaining that either the router or Linux is blocking traceroute. I have both SuSE 10.0 and SuSE 10.1 and a newer Linksys router and traceroute from my systems through the router work fine. 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. -- Jerry Feldman Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
