Do you have it listed in /etc/hosts? If not, is it known to your ISP's nameserver? Am I correct in assuming that gamma is connected to tilda via Ethernet (de0)? If so, pm1 should not be part of the route, since a gateway should only pass packets that can't be delivered locally. In this case, traceroute should return only a single line: gamma If gamma is not on an Ethernet connection, how is it actually connected to tilda? This list may lead you to the answer. If not, fill in the above blanks and I'll give it another shot. Ken
