Appreciate if if someone could enlighten me on the importance of these ports open on my router ?, Are any port which can be closed for [DOS Ack Attacks] "nmap" indicates that about 994 ports are closed.

This router's open LAN ports may be responding to your scan, even though you're scanning the WAN. Some soho routers are like this, their routing tables get short-circuited and respond on the LAN.

A true test would be to get a remote computer to scan you, like from a cafe's wifi, or try shields up: https://www.grc.com/x/ne.dll?bh0bkyd2
