At a client's office, their SonicWALL device is out of commission temporarily, so I've set up a Linksys WRT54G router in its place until we can get a fix.
They need some kind of VPN solution, though, for access until the SonicWALL is back online.
What is the easiest way to get a VPN setup configured between Windows Server 2003 and Windows XP client machines? I was thinking of something like Hamachi for the time being, but I'm not sure if doing it natively with Windows is easier...
