Hi,
I have a TPLink VDSL Modem (TD-W9960 v1 1.2.0 0.8.0 v009d.0 Build 201016 Rel.78709n) and TPLink Access Point (Archer c80 v1 1.5.7 Build 210308 Rel.60033n(4555)) on my network.
A LAN cable (192.168.1.2) reaches the AP working in router mode through its WAN port. They both have Wireless enabled, but I treat the AP as my secure home network.
Modem directs the traffic on all ports to AP with NAT-dmz forwarding. It also uses tplink ddns service to bind subdomain.tplinkdns.com to my public IP.
The AP has some NAT port forwarding settings for various services including http on port 80.
When I connect to the modem's wifi, I can access all ports via the ddns domain. (NAT loopback works even I am on the local network)
But when I connect to the AP's wifi, I cannot access anything on my local network neither using the subdomain nor my public IP.
NAT boost is not activated on neither devices as I read that it disables the NAT loopback.
Can you please help me to figure out how can I enable access to my local network servers via the domain.
Best
Before you start I would suggest to backup the TD-W9960 and C80 configuration just in case.
You will need these credentials for configuring C80 PPPoE session:
Delete the old Internet connection in TD-W9960 (PPPoE):
Add new Internet connection of type Bridge (click Save at the end):
Settings in C80:
After configuring the PPPoE in C80 click CONNECT (if available) and you should be able to establish the PPPoE session from C80.
You'll have an internet connection with a single NAT in C80 and since Kevin already confirmed the NAT loopback (hairpinning) implemented in C80 FW this configuration should resolve your issue.

No, you can't use the W9960 wireless in bridged mode for internet access or WDS. That's why I suggested C80 in AP mode in the first place.
Accessing W9960's WebGUI should be possible. You can try by adding a static route in C80 to the LAN IP address of W9960 via C80 WAN interface:
assuming 192.168.1.1 is the W9960 LAN IP address, and 192.168.0.1 is the C80 LAN IP address.
If above doesn't work try to connect your PC by ethernet cable to W9960's LAN port (Set static IP address 192.168.1.3, mask 255.255.255.0, gw 192.168.1.1 on your PC LAN adapter/disconnect from wi-fi if any) - then browse 192.168.1.1 (W9960 login page).
Hi @terziyski !
Thanks for your help. Your assumptions regarding the IP addresses of both devices on their respective networks were true.
But adding new routing entry with that information results this error:
When I check with subnet 255.255.255.255, as below:
I get this error which I don't understand its meaning:
