Task 1: Linux firewalld rules

My task was to add firewall rule to allow port 6300 on backup server.
I have added this to backup server using cmd:
sudo iptables -A IN_public_allow -p tcp --dport 6300 -m conntrack --ststate NEW,UNTRACKED -j ACCEPT

I was also able to telnet the server with the same port

could u please let me know why the task failed…

Hi Subhasree,

I think you were supposed to use firewalld instead of iptables to complete the task that’s why it failed.

Right, it is asked in the question to use firewalld not iptables.
