i dont think your going to get gilmour's tone through a toneport to be honest
here's a bud from another Forum doing it with Guitar Rig...
if you want the preset it's here:
Now running an Eleven Rack with Pro Tools 10.3.3 - it's amazing and I'm having ball with it - worth every penny. PT 10 is tops IMO and the Eleven Rack is a work of art!
i just recommend doing some experimenting bro, no ones going to tell you how to do it, its part of music, you gotta find out for yourself. especially with these new digital apps that lay everything out for you, it only gets easier.

just go easy on the gain, no crazy amount, lay some nice reverb in along with it, possibly a chorus and i think youll be on your way.
