You use a firewall to block unwanted traffic, which you almost always should in this tutorial, a firewall is needed to manipulate some of the traffic coming into the server. We need to modify this file with masking rules which is a concept that provides real-time dynamics for the correct routing of client connections. Before opening the firewall profile to add masquerade we need to find the public network interface of the device. To do this enter | Your public interface will be displayed after. For example this output shows an interface named as shown below Output defaults to raw static metrics Open the file to add the appropriate configuration After binding the interface to the default route Open the file to add the appropriate configuration This file handles downloading the configuration required for the general rules.
Add the highlighted lines below at the top of the file. This will set the default policy for the chain in the table and will block any traffic leaving Note Remember to replace the in the line with the interface you found Peru Mobile Number List in the command above. rules before Rules that should be run before adding rules on the command line. Custom rules should be added to one of the following chains Pre-Input Pre-Output Pre-Forward Start Rules Table Rules Post-Route Accept Allow traffic from Client to Post-Route Masquerade Crime End Rules Do not delete these required rows or you will get an error Filter . . . Save and close the file when finished. We need to enable forwarding packets by default. To do this we will open the file and find the directive inside it. We change the value from Default Accept Save and close the file when done. Open the port and enable.
The changes We will then configure the firewall to allow traffic to arrive. If you have not changed the port and protocol in the file then traffic should be opened on the port. If you changed the port and or protocol please replace the value you selected here. If you forgot to add it earlier we will also add the port which we can now disable and re-enable to load the changes for all modified files as our server is properly configured to handle the traffic. Steps Start and enable the service Now we are ready to run the service on our server. We can do this using . We need to start the server by specifying the filename from the configuration as an instance variable after that in the filename block. Our server configuration file is named so we add to the end of the file name when calling it by typing the following.
