   That's an argument between you and your ISP.  If you have Internet
access, then that's not the problem.

   But, while we're looking at that picture...

   BASIC > Internet : Internet IP Address : IP Address (as shown in your
picture) provides the same critical fact: 100.68.<blur>.<blur>.  Plug
that address into the form at: https://whois.arin.net/ .

   As you can see, that's not a public IP address.  My guess would be
that your ISP is using carrier-grade NAT, and that's defeating your
attempts at port forwarding.

   The only solutions I know are: 1) to ask your ISP for a real public
address (for which they might charge more), or 2) to use a tunneling
service like the one mentioned in another thread (near the end):

Some ISPs do not permit servers for residential customers, but I'm
confident that they'll tell you that if you ask.
