Hi!
I was playing with onworks.net, a site that host free VPS linux distro for a small amount of time, since we have root access I tried to make the server accept a connection from outside I used ufw rules. By doing
I got the server IP and, to a open a port I simply run netcat and added ufw rule: When I try to conntect with my computer There is no connections from the server, it just still listening.
I checked with rules have been added and same with It says that we can connect on port 4448 from everywhere (source and destination everywhere).
Now at this point I run nmap on the server port I supposedly opened it says FILTERED.
Can someone teach me what kind of firewall is there??
