The VPN uses "virtual" connections routed through the internet from the business's private network or a third-party VPN service to the remote site or person. So if the VPN were a VPN client to concentrator type of connection then I would expect IP TV not to work. And when I tested it at a customer site it did not work. However that customer also does site to site VPN (router to router) with IPSec and GRE tunnels. May 30, 2020 · How VPN Concentrator Works. The VPN Concentrator creates a virtual private network by establishing a secure connection called a tunnel, across the Internet that users see as a private connection. The device transmits or receives plain data packets in an encapsulating form through the above VPN tunnels for delivery to their final destination.

A VPN Concentrator vs. a Site to Site VPN: It is important to keep in mind that a VPN Concentrator is typically used in those scenarios where there is a One to Many (1: N) set up. This simply means that many remote employees are logging into just one physical location, where the server resides at. VPN Concentrator is a special type of router that creates a Virtual private network for large internal network infrastructure to be accessed by remote users securely. These include providing data encryption to maintain confidentiality and secure a private tunnel between two endpoints to maintain a sniffing attack.

Thus, you might want to choose a VPN concentrator that lists within its feature sets "automatic cache cleanup after session termination to ensure privacy of data," as the NetGear SSL device does.

But when I try to ping one IP of the remote VPN side (172.16.16.122 for example), this does not work. I managed to have this ping to the remove VPN client working only from within the pfSense console, after changing the "Local Network" settings in the IKE Phase 2 configuration, from "Local subnet" to "Network" with address "0.0.0.0/0".
