Hi, I'm trying to forward some ports on from my router to my PC but am having quite a bit of trouble. As you can see in the screenshot below. I have added both of the required ports to allow communications via my modem & PC. However when I check if the ports are open via the following website, it states that they are both closed. -https://www.yougetsignal.com/tools/open-ports/

   There's no reason to hide the Internal IP Address value(s). What is
the IP address of that target server? What have you done to ensure that
it always has the address which appears in the port-forwarding rule?

   Are you specifying the right external/public IP address for testing?
Is that the WAN/Internet IP address of the router?

   Is the server program running on the target server system?

   The usual problems with this stuff are:

   1. Wrong external IP address (different from the port-forwarding
router's WAN/Internet IP address). (An intermediate NAT router, for
example, could cause this.)

   2. Bad port-forwarding rule (wrong port(s), wrong target address --
including a wandering target).

   3. Server not listening on the port-forwarding target/server system.

  The IP address being used to test is that of my router.

       I don't know what that means. Which "the ipv4 address settings" do
    you mean? "whenever [you] assign a static IP address" to what? Are you
    fiddling with the settings on your computer (in secret ways)? I'd
    expect there to be an Address Reservation table under some location like
    ADVANCED > Setup > LAN Setup, and reserving an address there might be
    simpler/safer than trying to assign a static address on the computer
    itself.
    
    > The IP address being used to test is that of my router.
    
       Each interface of your router has its own IP address. The LAN
    interface has one, and the WAN/Internet interface has another one. What
    is your router's WAN/Internet IP address? (The first two octets of what
    should be your public IP address ("a.b" out of "a.b.c.d") will do, if
    you don't want to reveal the whole thing.)
    
       What is the target server ("Internal") IP Address in your
    port-forwarding rules?
    
    > [...] What is the IP address of that target server? [...]
    
       Still wondering.
