Does anyone know how to transfer files from one Wireless Local Area Network (WLAN) to another via the internet? I want to have read and write access to an externally connected hard drive at WLAN 2 so that I can transfer my holiday photos from WLAN 1, via the internet. WLAN 1 is a Windows (Windows XP Home Edition) computer connected to a WLAN that uses a dynamic IP address. On WLAN 2 there is an externally connected (Ethernet connected) Western Digital hard drive connected to a wireless gateway that uses a static IP address. I want to transfer my photos from WLAN 1 to WLAN 2 and vice versa. What is the easiest way (easiest and cheapest to setup) (and I know the easiest way may not be the most secure way) for me to access the hard drive on WLAN 2 from WLAN 1, without having to subscribe to a third party service provider e.g. Western Digital's MioNet service.

Easy way might be to look at Adobe's AIR acrobat.com stuff. Second easy would be to get barracudadrive 3.2 maybe. Most people use remote desktop but it does take some technical work to get to work in some cases. Some messenger applications allow you to share folders and files too. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

You could setup ftp software on both PC's. This would involve running an ftp server on both and having the client software on both as well. You would need router's on both ends that are capable of port forwarding to forward the ftp traffic from the router to the appropriate PC.
