Nostalrius Begins - Quality wow vanilla realm (1.12)

Is this allowed? I don't want the devs to suspect me of anything if I log in with IPs from countries far away from my regular IP.

That's how the target audience of Nost is able to play, you should be fine as well.

They mentioned that they are blocking new character creation over VPN links as one of the things they're doing to block the goldsellers. So you might have to connect normally the first time you make a toon.
