[FIXED] How to access / share Jenkins from another computer?

Issue

I installed jenkins (localhost:8080) on RHEL and I am able to build code successfully

Now, I want to setup master / slave agent.

My laptop will act as 'Master Jenkins' and my colleague's will be 'Slave'

However, my colleague could not connect to 'Master Jenkins' and we both are on SAME LAN and able to ping each other

I tried the following but nothing worked

(a)  Changed --httpListenAddress=0.0.0.0
(b)  Changed --httpListenAddress=<my laptop ip>
(c)  Changed --httpListenAddress=<my colleague's laptop ip>

and my colleague tried 'telnet <my laptop ip> 8080' from his laptop and did not work

Please help me to resolve this issue and I am new to Jenkins

Solution

Issue has been resolved by adding the port no '8080' in firewall

Goto 'Computer --> More Applications (or) Control Center --> Firewall --> Other Ports --> Add'
