VNC and NAT

That is correct, but as we know, the DHCP MAY change at the most
inconvienient times.  You can set up your DHCP server to assign
addresses only within a certain range and then fix the IP of the VNC
server outside of that range.  For instance, my network topology looks
like this:

Other network systems:
Router:   192.168.1.1
DHCP:     192.168.1.100 - 192.168.1.254

VNC Server:
IP Address:  192.168.1.10
Gateway:	 192.168.1.1
DNS:		 The DNS for your ISP.

This always works if you have access to your DHCP configuration.  If
not, well then there is nothing you can do.

Also, if your DHCP is due to your ISP on some sort of Broadband
connection, then I suggest TZO (www.tzo.com), they will fix an IP
Address to an ISP's DHCP.  But make sure that you have some sort of
firewall in place.

Hope that helps.

I am doing that with a 3COM router with DHCP and NAT.  All I
needed to do was go to the 'virtual server' configuration page
(configuration is through web browser), set ports 5800 and 5900
to forward to the machine with VNC server running, and enable
them.  Even with DHCP, the IP does not change often enough to
be a problem.  I think I've seen it change once in the past year plus.

YMMV
