My method is to open a local server, use software to penetrate the intranet, and good friends can join the game by inputting ip.
The first is to set up intranet penetration, and recommend cherry blossom FRP.
Register your account and enter the management panel.
What the management panel looks like.
Scroll down to create the tunnel and follow the prompts to create the tunnel.
The tunnel name is optional. By default, tcp tunnel is selected as the tunnel type, and comments are optional. Enter 127.0.0. 1 as the local address, and enter 7777 as the local port if tara rhea is online. In addition, the remote port is set by itself, ranging from 10240 to 65535.
Create a tunnel
Advanced settings are set by default. Click OK to create.
If the creation fails, it is because the port number of the remote port has just been changed with someone else's duplicate number. Change a number and click again to confirm the creation.
Create failed dialog box
If the prompt is successful, click the tunnel list on the left to see the tunnel you created.
Tunnel list
Then click Software Download to download the launcher (the first one will do).
Download and decompress, and open sakuralauncher.exe.
Unzip file
As you can see in the settings, you need an access key to log in.
Go back to the management panel, access the key on the right, click Show Copy, and paste it into the launcher to log in.
By the way, click on the daily check-in, and you can get daily traffic by signing in. The traffic is so heavy that you can't get online for 24 hours (probably)
Check-in flow
After logging in, click Tunnel to open the tunnel you created.
Find the log and your public ip address will appear in the log. Send it to your friends, add the ip address before the colon and the port number after the colon.
To do this, the basic work has been done. The next step is to open the game, create a good room, friends can join through ip!
