There are 2 ways to access it I think? I am NOT 100% sure both will give you the results you want.

1) DMZ, under the ADVANCED tab NAT FORWARDING in the Router GUI. Enable that LAN IP Address. Essentialy it puts that IP Address as if it was directly connected to your WAN IP Address. See this for more details, https://www.tp-link.com/us/support/faq/28/ as I think this will work the way you want it to work. You do need a 'server' running that will respond to the port 8080 request.

2) One USB page is a list of addresses for FTP access, one being for remoter. Use that and you'll have FTP access to the disk. Can't run anything though. Can run some 'stuff' like video's, but it is limited. You can READ from and WRITE to the disk though

Are there better ways of doing what I want? Mainly accessing files on my home network remotely. Install some software on my PC and an app my Android phone or othe PC/device?

Short answer, YES...

Long answer, it might not be 100% what you want or it might cost you some $$$$.

Remote access programs are what you want. You can transfer files both to and from a desktop. Run all sorts of things on your desktop like you were sitting there.

Here is a list of such programs, https://www.lifewire.com/free-remote-access-software-tools-2625161, and I have used some.

Free may not be the best choice. One I used produced a very small screen to work with. Some require the connected to system to have some settings made, and some do not allow unattended access.

TeaViewer is the one I like to use, both to assist friends who need some instruction/help (especially important to me with the Pandemic, and those not close by).  Check this link out, https://lifehacker.com/use-your-computer-from-anywhere-a-guide-to-remote-cont-5902654. All you need do is run it on your LAN PC and copy down the UID and PW.  Then from a remote location enter the UID and PW on the controlling PC and you will connect. You have all capabilities. I must tell you, TeamViewer has recently made it very difficult for 'free' usage. If they feel you are using it as a business they will lock you out until you buy a license. If you are lucky you can get the free usage back after appealing the lock-out.

There are other 'paid' ones too that will offer 'free' versions or Private, non-business use as well.

Windows for instance has a Remote Access built-in, https://support.microsoft.com/en-us/windows/how-to-use-remote-desktop-5fe128d5-8fb1-7a23-3b8a-41e636865e8c

Others I've tried, AnyDesk, Remote Desktop, Quick Assist, and Chrome Remote Desktop, all work, but may not support unattended access? TeamViewer is my go to.
