Answer from AI
To set up remote access to an internal network via SSH from outside, the following steps are usually performed:
-
Configure SSH server inside the network — ensure that the SSH service is running on the required server and access keys or passwords are set.
-
Port forwarding — configure port forwarding on the router or firewall to redirect an external port (usually 22 or a non-standard one) to the internal IP and port of the SSH server.
-
Use VPN or SSH tunneling — for security, a VPN connection is often created or SSH tunnels are used to keep access protected and limited.
-
Access restriction — configure the firewall to allow connections only from certain IPs or use two-factor authentication.
-
Dynamic DNS — if the external IP changes, set up DDNS for convenient connection.
Example command for connecting via SSH with a non-standard port:
ssh -p 2222 user@external-ip
Thus, remote access is provided through port forwarding and proper security configuration.
