+# Forward Multiple Ports Over SSH
+
+I sometimes find myself doing web app development on another machine via an SSH
+connection. If I have the server running on port 3000, then I like to use
+SSH's port forwarding feature so that I can access `localhost:3000` on my
+physical machine.
+
+```bash
+$ ssh dev@server.com -L 3000:localhost:3000
+```
+
+What if I have two different servers running? I'd like to port forward both
+of them -- that way I can access both.
+
+SSH allows you to forward as many ports as you need. The trick is to specify
+a `-L` for each.
+
+```bash
+$ ssh dev@server.com -L 3000:localhost:3000 -L 9009:localhost:9009
+```
