Inbound UDP forwarding on WAN port 443 does not work
This one is going to be a bit more technical. The behavior is super strange. I have an NH20T router.
I have a server thats listening on UDP 443. When connecting to it from LAN, the service works perfectly. My server is for sure not the issue here.
However, inbound UDP forwarding on WAN port 443 to my server does not work. The same destination and LAN port worked immediately when WAN UDP 18443 is selected. Rebooting and recreating the UDP 443 rule does not fix it.
The strange thing is that every other port and protocol works. WAN TCP 443 works. WAN UDP on other ports work without issue too. Its just that packets are not being forwarded on WAN UDP 443.

Is it possible you have a firewall that's blocking it?
The strangest thing was that portforwarding WAN UDP 443 degraded slowly over time. The first time it happened, I just disabled and re-enabled the rule. It proceeded to work for another evening. Next day, I reset it again and it worked for like 30 minutes. After that, never worked again.
I tried setting it down to "lax", but no difference made.
