- VPN Server site (L2TP UniFi-Security-Gateway), exposed to the internet (secured)
- VPN Client site (Ubuntu server connecting to VPN server)
- Reverse VPN between the sites, client can press "connect" for remote service.
This is because we do not want to rely on our clients to open firewall ports and aside of that we do not always have control over the client's router.
How can I connect the remote service PC to the client network (as if it was in the client network).
I simply want to be able to do a network scan from the remote service PC, to see if all devices are online and be able to access the webpages of the clients.
Currently the "Server (VPN client)" connects to my Unifi Security Gateway. Which makes the server able to see my local network/devices. But I am not able to see the remote network/devices.
I'm thinking that my "Server (VPN client)" would need to have a route from the VPN to the Client router.
But I'm not all too certain about how the "Remote service PC" can choose to connect the client network (possibly put the "Server (VPN Client)"'s IP as a router/gateway.
Please let me know if the above statements are correct or if this is not the 'usual' way to do this.
