Port Forwarding Help

Postby timbolinisan » Wed Oct 11, 2017 6:59 pm


I'm unable to open the port in Transmission. Transmission previously worked for me, but suddenly stopped working with the dreaded "Port is closed" error.

In my modem settings (Telus T1200H) I can confirm that UPNP is turned on, DMZ mode is disabled, and the port has not been manually forwarded.

Here is the Message Log output after toggling "Automatically map port"

I've also tried setting up port forwarding manually to a static IP address on my Mac, but get the same error.

Any suggestions? Many thanks in advance.
