Well, first, private-ip-of-remote-XP-machine is dynamic, given by my ISP's 
dhcp server, so I cannot have 100% guarantee that it will always be the same. 
And I have no easy way of finding it out if it does change.

Second, and more serious, I have no access to the NAT server, the ISP controls 
it. I may try using my username/password combination, but I am not sure what 
structure the ISP has. I mean, they may well have a NAT inside a NAT inside a 
NAT... However, I'll try it out to see if this kind of port-forwarding works 
in my case. :-)

Thanks for help!

Best, :-)
