Use SSH to Access VTuber with android

[philpw99]

There is already a generic guide telling us the methods:
https://docs.llmvtuber.com/docs/user-guide/backend/remote

I chose the SSH method because it works everywhere, no need to change anything in the browser, and no hassle of setting up certificates.
Here is how I did it:

1. Register a DDNS domain name for my router. Those domain names are generally free. I got my domain as "xxx.dyndns.org". Now this domain will always point to my router's Internet IP.
2. I enabled my router(Asus RT-AX1800)'s SSH feature. It allows using password to login, so I can just use the same admin login as the user/pass. I chose port 2200 as the SSH port because 22 is not recommended.
3. Downloaded the App ConnectBot for android. It's an excellent free SSH client with port forward feature. Once I added a host with the DDNS domain, filled in the user name and port, I can add this port forward to this connection: Type: Local , Source port: 12393, Destination: <my VTuber server's local ip>:12393
4. Now I can use ConncetBot to connect to my home router from anywhere. Once connected, I can open a new Chrome browser and go to address: "http://localhost:12393" to see the VTuber interface. Noted that microphone and camera are working as they should.

Note: After a few times of using it, the Asus SSH server might start to refuse the connection. I need to restart the router to fix it.
