I can ping an ethernet interface on a remote Cisco router, but I cannot traceroute to it. I have seen this behaviour before when a firewall is involved, and when some whacky access-list is applied to the interface. I was told the interface has no access list applied to it, so what other things can I troubleshoot when you can ping but not traceroute to an interface? -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org | Fax : (952)943-8500 Key fingerprint = 6C E9 51 4F D5 3E 4C 66 62 A9 10 E5 35 85 39 D9
