I was thinking of that originally, but then I was wondering about: Server on the PSN switches with IP address 10.0.1.5 starts broadcasting. Wouldn't GB1 start complaining because this IP address isn't supposed to be there?
And in that case, is it possible to tunnel one of GB2's external Aliases to a service located on one of the 10.0.0.x machines? Or do I have to double-IP everything? (Which isn't going to happen...)
