remote connection
 

hi
my linux is centOS 4.3 with gnome and kde and I install qmail for it.and it is in my office.
and it is at a LAN with invalid IP.because of administrative job what should I do to connect to it from my home(windows xp) through my phoneline(dial up).
that I could do everything in liunux system in GUI mode.
thanks.

If your speaking of invalid IP as it's using an internal IP not routable on the internet, just setup a port forward or ssl tunnel from the main routable IP address to this machine.
