Firewall question

[Dries Feys]

You have to bind an external ip adress to the internal one...  That way if 
you ping from the internet -  I assume - , you actually ping internal.

Hi Stuart,

Thanks for the reply! Port 5900 is currently open, as I *can* connect from 
*inside* the firewall to a host outside. The problem occurs in that I need 
the connection in the other direction, .. i.e. I need to make the machine 
*inside* the firewall the host, and I cannot see a way to connect from that 
machine as a host to a remote. (It is running an off-net IP address.) IOW, 
I need the 'host/server' (behind the firewall) to call the 'remote' because 
the host is NAT and can only support an outbound connection.

I cannot imagine that there are many others with this same sort of problem, 
as almost all of our clients have NAT boxes for their machines. If you have 
any ideas, please advise.
