Re: access to icq

Forwarding means that an incoming call is forwarded by the forwarding server
to another server. eg when I log into an FTP server having IP but
that IP is actually nothing more than a forwarding firewall, MY IP is
forwarded to the FTP-server that is actually behind the firewall. This FTP
server could have an private IP like or so.
The connection is established transparently through the forwarding server
which is masqerading the FTP server.

Hope this makes forwarding a bit clear to you? :)
