All 1000 ports are open|filtered - TheContradictor - May 5, 2020

Thanks to my seniors and peers here, I was able to bypass a firewall using nmap. However, now Nmap is showing all 1000 ports are open|filtered. I searched google for this but i could not do anything further. Could someone please help me out with what i should do next?

First thing first, there aren't ONLY 100 ports available on a computer.
There are actually 65535 ports open to TCP, and the same number open on UDP.

to do a FULL nmap scan

Code 
nmap [ip] -p-

My go-to for pentesting is

Code 
nmap [ip] -p- -T4 -A

To do a UDP scan add -sU

you need to scan all the ports not only 1000 using the quick scan when you scan all tcp ports it should work
