I can think of a couple easy options . . . although I'm sure with more thought there are likely more. TimbuktuPro - you can set the laptop to register itself with the Timbuktu server when it comes online and it will show up on the World List (I think that's what it's called) in the Timbuktu Pro console. This works fine but I think it might have needed an outgoing port opened. LogMeIn - If you install LogMein (www.logmein.com) on the laptop it will login to their server via port 443 (which is always open on a NAT router unless it was specifically closed which will break https). LogMein is cool . . . it establishes a three way VPN between the browser on your support machine and the client. It ranges from free to a few bucks a month depending on which features you need/want. BacktoMyMac is also a possibility; but this is trickier since you need a PnP capability in the NAT router.
