Daft question regarding DMZ on Hub2

[#1]

So we now have a Hub2.. 

On the Hub1 i opened up the windows incoming VPN ports quite easily - it worked well. Trouble is, i can't remember what they were!

If i were to turn on the H1 and give it a different lan IP, can i then set that as the DMZ on the H2 so that my incoming VPN connection still works?

If you go to Port Forwarding setup on the Hub One, click on "Manage Games and Applications"

From memory you should be able to edit your current rules, this should show the ports used.

If it's does not I can fire up my Hub One and check, but that would be later today.
