What do you mean by "blocked"? 1. The packets are lost somewhere in the cyberspace? 2. You receive an ICMP "host unreachable" 3. You receive a RST answer (connection refused) If (2), a sniffer would give you the IP address of the bad gateway. If (1), this might be a routing problem. Can you access other ports? You can try a "nmap". I've seen this kind of behaviour before. I could not SSH to a machine from my home machine, but I could from work. A nmap showed that only a couple of ports were "filtered". > Can anyone offer an avenue of direction on what I should look into next?

Firewalk should be able to find which gateways rejects the connection. http://www.packetfactory.net/Projects/Firewalk/ Hope this help. -- mailto:[EMAIL PROTECTED] GPG Public keys: http://michel.arboi.free.fr/pubkey.txt http://michel.arboi.free.fr/ http://arboi.da.ru/ FAQNOPI de fr.comp.securite : http://faqnopi.da.ru/
