Hi Team,

i did iptables restart, ipables-save, service iptables save , systemctl enable iptables are added the rule. but still not able to telnet from jump host.please help
i dont think anyone interested to help here 
I think that you need to place the rule in the top so other rules does not override it
iptables -I INPUT -p tcp --dport 3000 -j ACCEPT
you can use the -I option which allows you to specify the position of the new rule (or simply place it at the beginning of the chain by not specifying a rule number).
You can check your current iptables ruleset with
iptables -L INPUT -nv
Thanks for the assistance Devops503. Appreciate your inputs…
