How to forward port 443 on C1100T wifi router

Solution 1:

Port 443 was already taken by the router's Remote GUI Management. To free up that port:

  1. Log in to the wifi router.
  2. Go into the Advanced section.
  3. Click on Remote GUI on the left side menu under Remote Management.
  4. Enable Remote GUI and change the port to something other than 443 (such as 4433), then Save.
  5. Disable Remote GUI if you don't want it enabled, then Save.
