OK, I've read through everyone else's suggestions and have found that the best (and easiest) way is probably how I do it. From what I have found is depending on the size of your network, you can't open a hundred ports to access all of these machines. Best thing to do is install VNC Server on your linux box and pick a port. VNC into your linux box then VNC into the machines behind the firewall. 1 port opens up for all of your computers on the lan. As long as your network is not slow, you will have NO problem with it.

Hi folks,

there's a tiny masqueraded lan ( behind a firewall (suse 73, Susefirewall2), standard-configuration.

Task: Enable remote control of the internal computers via VNC.

The following already works:

(1) intern <-> intern
(2) intern <-> firewall
(3) extern <-> firewall
(4) intern -> extern

The problem is (5) extern -> intern

(currently i do a remote control of the firewall, which does a remote control of an internal computer, but that's pretty shitty)

I do not know the right questions. Is it a firewall-, routing-, or masquerading-thingie? How do I address internal computers anyway?

Please enlighten me.
Thanks in advance,
