If you only want to host a tribes RPG server local or lan or play tribes rpg online the following does not apply and you can just launch the mod and host or join servers and play. 
This guide is only for hosting a multiplayer server yourself that will show up on the master server list.

You can check if your server is showing up on the tribes master server list by hosting it and then checking one of these two websites that show the servers:
https://tribesquery.toocrooked.com/
https://tr1bes.us/master/

If your server isn't showing up you might need to forward ports on your router for tribes.
The incoming ports that need to be forwarded for Starsiege: Tribes Server are as follows:
TCP:
UDP: 28001

Forward ports on your router for tribes:
To set up port forwarding for
Starsiege: Tribes, log into your router, find the port forwarding section, assign a static IP to your PC.
Create a new rule for TCP/UDP ports 28001 (or the specific ports for your version/server), linking them to your PC's static IP. 
Remember to also configure your Windows Firewall to allow these ports. 

Step-by-Step Guide:

1)    Get Your PC's IP Address:
        Open Command Prompt by clicking the windows Start button and typing cmd to bring up Command Prompt, press enter to open it. 
		In the command prompt type ipconfig, then press Enter. Note your IPv4 Address (e.g., 192.168.1.100).
		The Default Gateway looking ip address is what you will use to login to your router settings in a browser.
2)    Set a Static IP (Recommended):
        This prevents your IP from changing. You can do this in your router's DHCP settings or directly in your computer's network adapter settings (IPv4 Properties) to reserve that IP for your PC. 
		
3) Log Into Your Router:

    Open a web browser and enter your router's IP address (Default Gateway address from ipconfig).
    Enter your router's username and password (check your router's manual if you don't know it).

4) Find Port Forwarding Settings:

    Look for sections like "Port Forwarding," "Virtual Servers," "NAT," or "Applications & Gaming".
	
	See the included PortForwardingExample.png to see what it might look similar to.

5) Create a New Rule:

    Service Name: "Starsiege Tribes" or something similar.
    External/Start/End Port: 28001.
    Internal Port: 28001.
    Protocol: Select TCP/UDP (both) or create separate rules for each if needed.
    Internal IP/Server IP: Enter the static IP address of your computer.
	
	See the included PortForwardingExample2.png to see what it might look similar to.

6) Add Firewall Rule (Windows):

    Open "Windows Defender Firewall with Advanced Security".
    Go to "Inbound Rules" > "New Rule".
    Select "Port," then "TCP," enter 28001, allow the connection, and name it. Repeat for UDP.

7) Save & Test:

    Save your router settings (you might need to reboot).
    Use a port checker tool or join a game to confirm it's working
