RE: Connection failed ?

The issue is not who brings the connection down. We suppose that it's not a
proxy nor a firewall problem and the configuration is correct.Let's just say
that is a cable problem. All I am asking is if kannel can handle this
situation.

or because the server closes down. 
It can also be a proxy server or firewall in the middle which cuts...
