Hi,
Any time I add to it, it generates a new entry but blank.
I had the same issue with the previous firmware.
Because port forwarding doesn't work. I have to put the system IP I need in DMZ in order to access to it.
Here is a screenshot of it after I enter RDP, TCP, *, 3389, 192.168.11.12,3389 respectively then click ADD
Thanks,
McR
