Question
I have a https jenkins server running on https on port 1444. I set the iptable rules but it does not work as expected.
I set the following iptable rules:
- iptables -A INPUT -p tcp --dport 22 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT # Since I want to allow ssh from anywhere into the host that hosts the jenkins server
- iptables -A INPUT -p tcp --dport 1444 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT #Since the jenkins server runs on port 1444. Note: The server is https
- iptables -A INPUT -j DROP #I want all other traffic other than ssh and https to be dropped
Is there something wrong I am doing while setting the rules? Please help

Hi @ksd17,
The rules look okay however I do have a question, how are you trying to access the application? Are you using a port or just typing in the domain name IE.
or
The second command should work, while the first one shouldn’t unless you’ve configured some kind of a reverse proxy, maybe with Nginx.
