B, i know this topic is old but it is the younger i found. Regarding connecting to a server through a company proxy, you said is impossible and that RealVNC made it running Enterprise Edition at both ends.
Well, is not like that, they just do it... i don't know how.
Right now i'm connected to my home-pc server. The server is Ultra VNC. Nothing special, just configured on port 80.
Client, here, at work, is REAL VNC Enterprise, and setting "use internet explorer proxy" and connecting to IP::80, works smooth.
I hope Ultra VNC adds this feature soon, because i really like it
Damn with the anti-spam thing... is almost anti-human!!!
