I going through my yearly (u/tight)VNC updates again and came across this new version.
I have some questions and issues here but I'll start with the questions

What ports does it use to connect to the server and host<>client?
Is this all going over port 80 which means we can avoid annoying firewall/vpn situations?
the issues...
I first installed the viewer (strange to call it viewer while it also is acting as a server?)
on a fresh Win7 Pro machine here on the LAN and entered the "group name" and a password.
then I installed the server on my machine and used the same "group name" and password.
After a few minutes my client appeared in the list. (red)
When I right clicked the client it seems attemping to connect and shows a flashing green progress.
After a while it stopped, I could see on the client that it attempted to negotiate or something but didn't success.
As I thought I installed it in the wrong order I went for a reinstall and created a package from in the Server window,
there seems to be a bug aswell the package (pchelper.exe) it created starts a 7zip extractor window but then it hangs and doesnt extract anything at all,
tried on the Win7 and XP box, same lock-up.
When I created the package again the pchelper.exe file is 95Kb larger and executes/extracts just fine?
Besides that it still doesn't connect, do I need any specific port forwarding or are server & client just using connections to the middleware server?
