OK, now I understand it sounds reasonable.

But by placing that "PC than must not behind NAT" where it is it will not
(as in NEVER) be able to be reachable by the PCs on the LAN side of the
router behind NAT because that is the way these routers work. As far as they
are concerned that PC is out on the internet somewhere and the whole purpose
of NAT is to protect your LAN from the Internet. 

You could try placing the "PC than must not behind NAT" on the LAN side to
the router (i.e. take it off the hub, plug it to a LAN port on the router)
and configure the router to place that PC in the DMZ (see pg 45 of the user
manual, befw11s4_v4_ug.pdf). That way it is effectively now not behind NAT
but it is on the LAN sub-net and so is reachable by the LAN PCs. Just
understand that doing this means it is effectively out on the internet (but
then it was anyway on the hub) and has none of protection offered by the
router thus a good software firewall is essential (and all that that entials
in getting VNC working! :-))

As to your last question. VNC should work with that (inasfar as I have
experience of it) but you should note that most of these simple broadband
routers normally can only port-forward a port to a single LAN IP address (ie
a single PC); I can't speak for the Linksys, consult the documentation on
that point. Thus you will have to carefully set up multiple port-forwardings
(of ports 5900, 5901, 5902, etc) to point to individual LAN IP addresses if
you need to use VNC to/from more than one PC and adjust VNC
Display:-Display:9 accordingly on each PC to correspond with the port in
use. Furthermore if you do adopt this approach you will probably need to
make your LAN IPs static (otherwise there is the chance that DHCP will
allocate PCs a different LAN IP address the next time they re-boot rendering
your map of port-forwards to LAN IP address in-operable). One way of doing
this is to give the PCs manually entered IP addresses outside the range
allocated by the DHCP on the router. Some routers (e.g. Netgears) offer the
facilty to map a specific PC MAC address to a specific LAN IP address, a
quick skim of the Linksys did not reveal this feature, but again check the
documentation.

The use of ssh for secure connection is also a consideration (I use it to
connect to work PCs where the corporate LAN firewall blocks VNC access on
port 5900).
