Opening Windows Firewall Ports

Windows Firewall configuration is required to allow game server connections and administrative access. This guide uses FiveM server ports as an example, but the process applies to any game server or application requiring port access.

Example Port Configuration (FiveM)

This guide demonstrates configuration using FiveM's standard ports. Replace these with your application's required ports:

Port	Protocol	Purpose	Required
30120	TCP/UDP	Player connections	Yes
40120	TCP	txAdmin web interface	Optional

Creating Inbound Rules

Initial Rule Setup

1. Navigate to Control Panel > System and Security > Windows Defender Firewall
2. Select Advanced settings
3. Click Inbound Rules in the left pane
4. Right-click Inbound Rules and select New Rule

TCP Rule Configuration

1. Select Port and click Next
2. Select TCP
3. Select Specific Local Ports
4. Enter 30120 in the port field
5. Click Next
6. Select Allow the connection
7. Click Next
8. Select appropriate network types (default settings work for most configurations)
9. Click Next
10. Enter a descriptive name such as "FiveM TCP"
11. Click Finish

UDP Rule Configuration

Repeat the above steps with these modifications:

• In step 2, select UDP instead of TCP
• In step 10, use a name such as "FiveM UDP"

Additional Port Rules

Create separate rules for port 40120 using the same process if txAdmin web access is required.
