This application will enable the user to automatically block ports for Grand Theft Auto Online, which allows the user to play in a 'public' session by themselves or with friends only. A public session has more benefits than the in-game friends-only session.
Windows 7 or later and Java SE 8 or later are required for the program to function correctly. Additionally, administrator privileges are required to modify the Windows Firewall.
This is a standalone application, so no installation is required. It is recommended to extract the contents of the zip to an empty folder.
However, first time firewall setup is required.
The batch file setup.bat will remove any default firewall rules for Grand Theft Auto V, and replace them
with its own. Read the rest of this section before continuing.
You are advised to create a backup of the Windows Firewall before using setup.bat. To do so, open Windows Firewall with Advanced Security (Run -> wf.msc), and right click on on the main tab on the left (Windows Firewall with Advanced Security on Local Computer). Then export policy and save the backup.
You also must set the location of GTA5.exe (the game) before running setup.bat. The location of GTA5.exe is in the main game folder. Edit setup.bat, and replace the given location (on line 3) with your location. Make sure that you keep the double quotes around the location.
Then run setup.bat as administrator.
You can add friends on the left panel with the 'Add...' button. You then need to provide their name and their public IP address. To edit an existing friend, simply select them on the left.
The firewall rules created previously are automatically updated when you save in the application. It is recommended to save the information file with the default name (info.bin) as this file gets automatically loaded when the application starts.
When a friend is not selected, you are able to enable / disable the blocker with the buttons below the output console. Remember, you cannot join another player while your blocker is active, and non-friends cannot join you.
The blocking state is remembered between sessions. This means if you leave the blocker on when you close the application, it will continue blocking while not open.
Public IPs are often not static, and can change seemingly randomly. If a friend cannot join you, get them to send you their IP again. Chances are their IP has changed automatically.
If you get randomly disconnected from GTA Online, it is likely because your friend was the host of the session instead of you, and somebody not on your allowed IP list (a random) was matchmade into the session. This results in your game not being able to communicate with the random player, and you get disconnected. To ensure that you are the host, use the 'block all' feature to get into a session with only yourself, swap to the regular block all but friends, and then invite your friends.
