This tutorial will teach you how to configure WildFly or JBoss EAP to run through a firewall.
To configure firewall rules on a Linux machine you can use the command-line tool firewall-cmd which is part of the firewalld application, that is installed by default. It can be used to make permanent and non-permanent runtime changes.
Typically, you would allow the HTTP port to be reached from outside. So, to allow the port 8080:
sudo firewall-cmd --zone=public --add-port 8080/tcp
The above rule will not however survive a server restart. In order to make it permanent, you would need to add the –permanent parameter:
sudo firewall-cmd --zone=public --add-port 8080/tcp --permanent
On a Windows machine go into Control Panel and click Windows Firewall. There select “Allow an app or feature through Windows Firewall” and it will open this window:
Next, click on “Change Settings” and select the “Allow another app...” button and in the next window choose the Browse button next to the Path field.
You will need to add the WildFly service so that it can run through the Windows Firewall
