For #1, I can still try to find the guide of how to do this. But the performance of ssh proxy is not good. Actually now you can have your own vpn server easily so you can use vpn. VPN server is in all of the mini routers (not USB) firmware v2.27. You can connect USB150 to your vpn server.
#2, What is the reason of going back to 2.5? I think that is a beta version.
