since this is mobile network and ISP's do all kinds of tricks, you should first verify that the IP your router has 172.173.4.149 is the same as what websites see.
you can do google search for "what is my ip" or use
https://www.yougetsignal.com/tools/open-ports/ to check, it's port checking works for all games that I know of too. (provided server/game is running at time of check, if not, no one is listening on that port)
If router IP and external website IP's are different, you cannot port forward, your ISP is blocking that feature on mobile (not at all uncommon)
Past that, whole setup seems like a mess, I mean, your routers LAN IP is 0.1 and mask allows only last number to change.
your computer has 48.71 and subnet mask allows only last number to change.
based on that, unless something is really weird, your router and computer should not even be talking to each other. (like unless you are connecting to router with wifi and did not mention it)
so.. while I'm 99% sure your connection/forwarding will never work due to ISP's not liking port forwarding on mobile, it is also likely that even if that part would work, your router/computer is most likely set up so that it wont work anyway.
the computer/router/lan setup you can change to work but ISP side you cannot, so you should first verify that routers IP matches what webservices see, if it does, you should be able to get it to work
