Just an FYI that I tested yesterday evening using IPv6 and a windows 7 home computer.
Windows 7 plugged directly into H1000 - gets a IPv6
Ran ipconfig - got my IPV6 for the computer.
Setup a IPv6 tunnel using the free software at
Ensure Windows Remote Desktop was active and the Windows 7 fireway allowed access for Remote Desktop.
Ran the client software from freenet6, entered the IPv6 address obtained as as described above and ran Remote Desktop client - bingo - access.
Tested from my Wireless Internet hub over 3G...also tested this morning from work.
Proformance is as excepted - Delay as expected for Sat.
You need to run a IPv6 tunnel/broker for this to work. Not very practical for normal use.
