Feedback on New OpenVPN tunnels

Proof of concept, more than effective needs…

Assuming Green Lan 1, and Lan2

Assuming than Lan2 needs only few services on LAN1, just like an FTP Server, a DB server, a Printer server and an Application Server, which are on different IP addresses on Lan1.

With NAT on OpenVPN, i could use only 1 IP address for allow access to all that services on Lan1 with port forwarding from OpenVPN adapter (for instance
Without NAT, i should use specific firewall rules for allowing services/ports to the Ip addresses located on Lan1, and configure clients to “look for” the services and the IP addreses on Lan1.

If Lan1 and Lan2 are connected via OpenVPN and both servers are NethServer, you don’t need to do anything: clients from Lan1 can already access services of Lan2.

Otherwise you could create a port forward which allows the entire VPN network.

With a couple of boxes i just had a taste of OpenVPN Tunnels.
Holy kamoly!
Works like a charm. The fastest experience of create VPN Tunnel, i am really astonished.

I had a little plug/unplug test of the RJ45 connector on the client red interface. Two seconds after plug back the connector i had a ping back from a device on the other side of the tunnel.
Again: astonished.

A big thumb up for @dev_team and @giacomo


You need to add a box to set custom options for openvpn cli tunnel.

I need to add router directly in the config client:
