Description bpinaud 1999-11-16 13:45:29 EST
I'm a network administrator and on my network, i use an ipchains based
firewall. When i do a traceroute on the firewall the only hop that appears
is the end of the traceroute. On a workstation behind the firewall i've got
two hops : the firewall and the end of the query. On a workstation with
windows 98, traceroute works fine. The Linux workstations are under RH6.1
and the firewall is under RH6.0 with the latest version of ipchains.

This sounds like a firewall configuration problem. Different traceroute tools
may happen to implement their functionality using slightly different network
protocols (e.g. ICMP vs. UDP). It's not a bug in these tools - if you want them
to work, you will have to configure your firewall accordingly.
