Hi Bobby,
If you mean version 5.1 it's been available since the 12th of December :) To be exact, the most recent version right now is the version 5.1.1. It's downloadable
here.
Regarding the tunnels etc. RUT does not create a VPN tunnel. However, if the network environment on either side (remote or local) is restrictive and only allows port 443, the program automatically uses port 443 provided that you connect using the
Internet IDconnection.
Also, in the version 5.1.
proxy settings are available for both Server and Viewer.
