Luckily, Bethany can reach Daniel's public SSH server, which means that Bethany can make it possible for Daniel to connect to her website – by configuring a remote port forwarding connection. Unfortunately, it is not reachable to Daniel. Usage exampleīethany is developing a personal website on her laptop and wants Daniel to check it out. See also: Remote port forwarding (a Wikipedia article). This type of port forwarding redirects connections made to a port on a device running an SSH server to your device (with Termius) and then to any reachable port, on your device or another one. Remote port forwarding is mostly used to give access to an internal service to someone from the outside. Tap Save / ✔️, then tap the port forwarding connection to activate it.In the Port to field, enter the number of the port on the end device that should receive the traffic.In the Destination / Host to field, specify the IP address or domain name of the host to which the connections should be ultimately forwarded.Specifying a number greater than 1000 and less than 49151 should probably be fine. In the Port from field, enter the number of the port that you want to be forwarded.In the Host / Host from field, specify the host that should act as an intermediary.(Optionally) in the Label field, provide a name for the connection.Choose Port forwarding in the main menu and tap +.Click ➔ at the top right to hide the connection's details.ĭouble-click the port forwarding connection to enable it.In the Destination port number field, enter the number of the port which should receive the traffic.In the Destination address field, specify the IP address or domain name of the host to which the connections should be forwarded.

In the Intermediate host field, specify the host that should act as an intermediary.

If you skip this field, Termius will bind to 127.0.0.1, which means no other machine will be able to connect to the port being forwarded. (Optionally) in the Bind address field, specify an IP address of your device (network interface) connections to which should be forwarded.You can use any port number greater than 1024 and less than 49151. In the Local port number field, enter the number of the port that you want to be forwarded.field, provide a name for the connection. Choose Port forwarding in the main menu.He will then need to specify 127.0.0.1:3336 as the address of the MySQL database in his local MySQL client. The OpenSSH analogue of that connection would be ssh -L 127.0.0.1:3336: 10.1.30.42:3306 activating this port forwarding connection in Termius, Daniel will forward the 3336 port on the 127.0.0.1 network interface of his device to the port 3306 at 10.1.30.42. The settings shown in the above screenshot would solve the problem Daniel has. He can connect to the database using a local port forwarding connection. The laptop runs an SSH server and is reachable from Daniel's device with Termius.

Usage exampleĭaniel has a MySQL database server that is not reachable from his device with Termius, but is reachable from the daniel.local device, which is his office laptop. See also: Local port forwarding (a Wikipedia article). This type of port forwarding redirects connections made to a port on your device running Termius to a device running an SSH server and then to any reachable port / device. Local port forwarding is most commonly used for connecting to services on a private network, such as a database or VNC server. Termius supports all types of port forwarding: local, remote and dynamic. SSH port forwarding can be used to gain or provide access to services that are not directly reachable, to encrypt connections between different applications and more.
