TomatoUSB

Hi all, i'm new to the forum (and I only heard of tomato a couple of hours ago!) so wanna say hi!

I'm looking for a router can solve the age old Apple TV needing a VPN issue and it looks to me like Asus RT-N66U and TomatoUSB would be the way to go. The question I have is…. Is it possible to have 2 available wireless networks one of which is a VPN client/network and one that isn't?

Is there a router than can achieve this magical task or do i need two router?

Thanks for any help!
