What setting needs to be checked and what needs to be done on the
machine that openssh server is running and on the router that machine
is connected to, so that openssh server can be accessed remotely?

You need to open port 22 on the router.  But I strongly advise not to
do that until you have done a lot more research into the perils of
opening your system up to the internet, and how to minimise the
danger.
