Hey Scott, I told VNC Server to listen on this port through "Options" -> "Connections" -> "Accept connections on port: " -> 27036. I just checked with netstat -an and indeed the PC is listening on that port (amongst others) Indeed, I want to connect to that pc with some.dyndns::27036. When I connect from a PC inside my network, netstat says: TCP 90.0.0.241:27036 90.0.0.2:4674 ESTABLISHED and the windows Eventlog says "Connections: accepted: 90.0.0.2::4674". I disconnect and reconnect to the VNC, and this time the port is 4680: TCP 90.0.0.241:27036 90.0.0.2:4680 ESTABLISHED I guess that's the reason why it can't get past my (nat-)router: Only the range 27031-27039 has been opened... When I try to connect from outside, these three messages appear in the eventlog: Connections: accepted: 81.240.207.222::4707 Connections: closed: 81.240.207.222::4707 (write/select: Connection reset by peer (10054)) EventSocketManager: write/select: Connection reset by peer (10054) Cheers, Johan -----Oorspronkelijk bericht----- Van: vnc-list-admin@xxxxxxxxxxx [mailto:vnc-list-admin@xxxxxxxxxxx]Namens Scott C.

Just checking: if you open a command-line on your Windows PC (Start -> Run -> "cmd"), and then "netstat -an", can you verify that something is listening to "27036"? I'm not sure how you "told" the VNC Server to listen to this port, but the netstat command will tell you if it did. Also, on the Viewer side, how did you tell it to connect to your PC's port "27036"? I assume you typed in something like "external.ip.address::27036"? cheers, Scott > Hello, > > I'm trying to run 2 PCs with VNCserver (4.1.7) behind my router.
