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.
Hmm funny you should mention this.... I have a bunch of routers, Linksys, Dlink and an expensive Xincom. Traceroute works fine on all the routers but the Xincom. Nothing comes back from the traceroute or at least it's all * * * * * HOWEVER........ even when the Xincom is in place, if you do a traceroute from either a Windows machine connected to the same router, OR a windows machine running under VMWare within a linux machine where traceroute is failing, the windows traceroute will work!! Strange.... but if you can do it, have your friend try a Windows machine or maybe some other operating system behind the same router. It is something within Linux that doesn't like what the router is doing to traceroute. I've investigated it a little bit but not exhaustively. Maybe someone here has a clue.
