While talking to the admins, you might show them your traceroute too. It's a bit strange that bbrb-isp.Stanford.EDU responds to traceroutes from the outside, but not from your internal machine. Of course it may be that the port 80 blocking (and/or traceroute blocking) is occurring on another router between you and bbrb-isp .. we can see at least two. > When I filter out non-tcp traffic nothing shows up at all.
