Model : Archer C9

Hardware Version :

Firmware Version : 1.1.2 Build 20161025 rel.45517



I need to set up port triggering for the following ports (UDP):

30840-30859, 30870-30879

However, my router (Archer C9 v3) won't let me input a range of ports on the "triggering port" field, only on the "external port" field, since the range is big I can't input each port as a separate entry either.

Am I doing something wrong? I looked for an update for the firmware of this router however I couldn't find it anywhere, the version running on my router is 1.1.2 Build 20161025 rel.45517.
