Unfortunately, END EXTERNAL ports 22, 23, 53, 80 and 443 are restricted on the DG8041. The issue is with the developers ATM. You can, of course specify, say, port 80 as in internal port and, say, 9080 as the external port and use port redirection with a DDNS provider to direct an URL.
However, if you need to use LetsEncrypt or another service that requires one of the restricted ports your only option is to use a different modem/router.
The support team here may swap the Huawei for the Sagemcom if you ask.
For TESTING PURPOSES ONLY you can specify the start and end external ports as zero (0). Be aware this will open ALL external ports for that rule, so make sure your firewall is up to scratch first.
