   Please use a sniffer like Wireshark and check which ICMP packet you   
   receive. E.g. Telnet gives "No route to host" even when the ICMP Type 3   
   Code 13 Communication Administratively Prohibited is being received.   
      
   A rather confusing message.

   Some stupid default settings in firewalls return port unreachable   
   instead of admin prohibited. This might be the case too, but check the   
   packets first.
