VNC over VPN questions

I'm running VNC over VPN between two PC's running Windows XP SP2 and
Windows 2000. Both machines are behind hardware firewalls (SMC Barricade
the Windows XP PC, Sonicwall for the Windows 2000 PC), but as they are
connected by VPN I believe that is not an issue - no need for
Windows 2000 PC is on a LAN and has a static internal IP Address.
Windows XP is on a home network and uses DHCP - however, when the VNC
server is running
putting the mouse over the VNC server shows an internal IP address.
Windows 2000 PC as server and Windows XP PC as client works fine.
Windows XP PC as
server and Windows 2000 PC as client (connecting to the internal IP
address as noted above) does not work ("Failed to connect to server").
The Windows XP PC is running the Windows XP SP2 firewall. When I tried
to run VNC server from the Windows XP PC, I was asked if I wanted to
server an exception to the firewall. I said no, as I dont want to allow
VNC connections except over the VPN connection. Is this my problem?
Also, our hardware firewalls are set up for defaults, which I believe
would keep all ports closed unless specifically opened. I cannot connect
using the external IP
address,and can only connect to the internal IP address if VPN is
running, so I think I'm safe. But it would be nice to get confirmation.
Last, I also use unix boxes running solaris as VNC servers. It seems
(from the flavor of FAQ's and postings to lists such as this) that when
using a unix server, I can
only view "virtual machines", I can't use the VNC viewer to see the
physical desktp of the console of the server that VNC server is running
on. When using a PC
server, the opposite is true; I can only see the physical desktop of the
PC that VNC server is running on; I cant view virtual machines. Is this
correct? Why is it so
If it makes a difference, I'm using TridiaVNC. Thanks in advance for
any and all help.
