Not able to access Tomcat webserver from another machine in the LAN

Question

I have setup the basic tomcat website (tomcat 8.0.3) on a server inside my company LAN. From my work computer if I try to access the website by typing it into google chrome it is not working.

The IP of the computer on which the Tomcat server is running is 192.1xx.132.125:8080. The IP of my work computer is 192.1xx.129.75.

I am able to ping my work PC to the server. If I type http://192.1xx.132.125:8080 on google chrome browser on my PC I get the following error.

Google Chrome error!

Can someone please point out why this is happening? Also My webserver is headless.I can access the webpage on that server using curl. Since this is a non-conventional port number do I need to update the IP tables on my server?

I have run this command

 sudo iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT -m comment --comment "Tomcat Server port"

as mentioned in http://serverfault.com/questions/341804/opening-up-port-8080-in-centos

Ok, Try to test enable port 8080 `iptables -A INPUT -p tcp –dport 8080 -m state –state NEW -j ACCEPT`, also check if tomcat is listening with `netstat -ant | grep 8080` — Federico Sierra, Mar 24 '15 at 02:09
@FedericoSierra - no output for iptables command.But tomcat is listening on 8080 — liv2hak, Mar 24 '15 at 02:23
Seems you have Centos 7 try `firewall-cmd --zone=public --add-port=8080/tcp --permanent` and `firewall-cmd --reload` — Federico Sierra, Mar 24 '15 at 02:28
@FedericoSierra - Very Impressive.It worked.Thanks :) Do I have to save that so it is not lost across reboots — liv2hak, Mar 24 '15 at 02:30
You do not need anything more, the rules were applied permanently (`--permanent`). — Federico Sierra, Mar 24 '15 at 02:33

For Centos 7 you can enable the port 8080 with the following commands:

firewall-cmd --zone=public --add-port=8080/tcp --permanent 
firewall-cmd --reload
