Change server sshd_config to allow client binding artitray network interface
```
GatewayPorts yes
```
Use -R [bind_address:]port:host:hostport to setup port forwarding. bind_address should be 0.0.0.0, which means binding on all network addresses. Following example forward local ports 3000 to server 8080, and local ports 22 to server 2222. So others can open http://server:8080 to access your web server, and ssh -p 2222 server to log into your local machine.

ssh -R 0.0.0.0:8080:localhost:3000 -R 0.0.0.0:2222:localhost:22 server
