Port Redirection

Post by Mirin »

Hi.

Can any one help with this question...

I need to change da port that Ultr@VNC Viewer (Listen Mode) is wathing by default (port 5500) to another one. Is this possible????

This is because the cliente request comes in port 5514 and my router only translate ip(public):port request to ip (private), soo the request arrives to my computer in port 5514 but Ultr@VNC Viewer (Listen Mode) is wathing in port 5500.

Thanks in advanced.

correct: SC standard port
winvnc -connect main.enterprise.tld:5500
vncviewer -listen 5500

correct: SC (non standard port)
winvnc -connect main.enterprise.tld:5514
vncviewer -listen 5514

wrong:
winvnc -connect main.enterprise.tld:5914
vncviewer -listen 5500

Hi again.

Many thanks for your replay.

It works just fine.

Change listening port on listener to 5901

Post by krein »

start - run -

"C:\Program Files\UltraVNC\vncviewer.exe" -listen 5501

This will launch the listener on a different port allowing you to setup more than one workstation on the same network to listen.
