Hello,
In a local network that using a gateway device for sharing the internet between clients, how someone from outside of the network can connect to a client with SSH?
In the local network, clients using the local IP address and the global IP address is set at the gateway. If the client uses a VPN and then give the IP address of the VPN to someone out of the network, then can others use this IP for connecting to the client with SSH?
I know that with write a routing rule in the gateway, anyone can connect to the specific client, but I want to do it without routing.

Thank you.

You can use a feature on the gateway/firewall named "Port forwarding".
