Cant find public game on same network

[Thunderbird 98]

I asked for help with this on the discord server, and nobody answered. I really need help.
I want to host a public game and i want my younger brother to be able to play with me. When I host, other people can join, but when my brother searches on server browser for my server, he finds every game except mine! When he tries to join via ip address, nothing ever loads. I really need help!

I think this is a little different. I've done everything in that tutorial right.

You can try having him connect to your local IP address instead of your public one. It usually follows the format 192.168.1.*. Seems a bit strange that he can't join with your public IP—is it blocked on your firewall?

This solution is for PC users

Just make for your young brother at his SRB2 folder a .bat file, which it gives parameter for his client port to a random value, except 5029 because you use its port for hosting. So make his -clientport to 5030.
To make a .bat file, create a text file by Notepad, type this line here "srb2win.exe -clientport 5030" without the quotes and save as .bat not as .txt and make Notepad's "Save as type" to "All files (*.*)"

Open its .bat file. This will launch his game in different clientport, now he will try to find your public game. This .bat file is at attachments

If he can't find it at the server listings then connect by manual, local IP address. Use 127.0.0.1 or 192.168.*.* where the stars is the complementary of your IPv4 Address
