Hello,
I have just changed from a fibre router to a TP Link Archer MR200 and I’m having trouble setting up the port forwarding for my camera system (DVR). The DVR has a fixed IP 192.168.1.12 and port 7000. I have set it up as shown in the screen shot.

I tried a couple of port checking tools, but the port is closed. What am I doing wrong?

Another curious thing with this router is it states that the internet IP address is 10.164.213.13, but on the port checking tool it shows as 148.252.129.230. Why is it different? I tried typing in the IP from router, but the port checker still fails.

Any advice would but much appreciated.
Thank you,
Mick
