[thelist] A question for people who know routers....

Could be bad routing table configurations, or more likely, a firewall, host
TCP Wrappers, or extended access list at the router would prohibit certain
kinds of IP traffic from coming in.  Where does it time out when you do a
trace route?  You can tell at the router hops where you're traffic is going
or not going, but often times ICMP & UDP traffic are blocked as well (they
are DoS risks)....*sigh*   Look for more and more of this after Y2K as
security and Internet paranoia take a stronger hold.
