VNC Ports

Hi,

Please can someone tell me which ports i need to have open on my router to access a pc on my network remotly with VNC via the internet. I would like to use the built in web based java control page if possible.

Thanks
Jack

check the options within the vnc server app? or check the online docuementation of whatever program you are using. i imagine the web/java thing will run on port 80 (standard webserver port).

I think you can change the port which it uses but I think it uses Port 5900 by default

you need to setup port forwarding not open the port. this will point that particular port to the local IP address your pc has on your home network.

if you think about it. the router can have a number of pcs connected. when you connect from a remote location, how does your router know which pc you are trying to access?

btw - its usually port 5900

The answer to this is tcp port 5800 (by default) for the web based (java) version, and tcp port 5900 (by default) for the client (vncviewer.exe) version.

you just point it to a specific ip address on the internal network. easy.

He's got it.

Linux for some reason starts numbering the VNC screens at 1 IIRC... so that would be 5801 and 5901 respectively for that. :confused:
