I would check for problems with reverse DNS. Try the command "dig -x
<IP address>' (and try with your IP and your development server's IP).
Dig should either return with a DNS name, or it should immediately
return with an unknown name.
If you're using your own DNS servers for internal IP addresses, try
adding zones for reverse DNS in your internal IP nets, even if the zones
How long have you tried waiting for SSH to return? It shouldn't hang
forever, only 6 minutes or so, if it is a DNS problem.
