Hello,

I have a TL-R480t+ and a Raspberry Pi 3, and I want to access it via VNC, I want to forward port 5900 to the Pi´s IP Address, but every time I want to save the rule the TL-R480t pops a windows that says "The External Port you entered has been assigned." and no rules is saved.

 

What can I do?

Is this normal in a TL-R480t+?

 

TL-R480t+ (Ver. 5.1) Firmware 5.1.2 Build 20130116 Rel.45581s

 

Thanks

Hi Marco_Smith

Have you already configured an port forwarding entry for port 5900? I think every external port can only be used in one entry. 

If you have configured other entries, maybe you can try to reset the router and try again.
