The Power of SSH Reverse Proxy

ssh -N -R 10086:localhost:8888 root@172.0.0.1

This command can map the local 8888 port to the remote 10086 port. If you need to allow the machine at 172.0.0.1 to access the internet through the local machine, you can simply run an HTTP proxy service with port 8888 on the local machine, which is very convenient.
