I have the LS-WVL849 NAS. I set up Webaccess to access my NAS from my phone and my school. One of the only open ports at my school is port 7777, so I set the external port as 7777 and the internal port as 9000, the default. I forwarded port 9000 for the IP of my NAS, and I cannot access Webaccess through LTE. When I choose to auto configure ports, it goes through immediately. I have also tried it on different ports such as 8080, 7777, and 443 but none of those work. How can I make the external port 7777 and be able to use Webaccess?
