Archer A20 - Port forwarding doesn't work if request comes from "self" device.
Hello.
I swapped out my AX21 for an A20 recently. I have a server that hosts some web sites and services (ports 80/443) and a domain name that points my WAN IP. I have those ports forwarded to my local server's internal static IP. The server is on a 5-port switch that's connected to the router.
Everything worked fine on my AX21. But with the A20, any device that's on the switch is not able to reach the web services through the WAN IP or domain name. I can ping the IP or domain name from those devices, and I get a response from my router. But traffic on 80/443 isn't getting forwarded for these devices. My wifi devices can reach it fine, though.
I tried connecting the server directly to the router instead of going through the switch. That resolves the issue for all devices except the server itself. It needs to be able to connect to itself using the domain name.
Any idea why this is happening and how to fix it? The software that needs to connect to this server would be kind of a pain to rewrite so it could use the internal IP on port 80 from local devices.
Thanks!
