Hi @essientops 

Thanks for posting in our business forum.

Here's the solution to it, change the port of HTTP and HTTPS of the router to a different port.

But I think you should know that one IP can only have one port working. If it is occupied, you should change to a different port. This is pretty basic and if you have trouble with this, please hit Google and prepare yourself for this knowledge in the future web hosting and port forwarding.

  @Clive_A  Pleas can you show me how i can disable port 80 on er605 using OC200. Thank you in advance

If it is adopted, then this cannot be changed. Only when your router is in standalone mode, then you can change the web port. This can be found in the User Guide.

If your router is managed by the controller, there is no way to disable the ports.
