Regarding Application Security task failed

Hi,
I added the below rules:
iptables -A INPUT -p tcp --dport 8092 -j ACCEPT
iptables -A INPUT -p tcp --dport 6300 -j REJECT
and
started the service
also saved the state using:
service iptables save

but the task failed.
kindly help reviewing the same.

Also terminal was having issue for route
