IPsec VPN gateways

A VPN gateway functions as one end of a VPN tunnel. It receives incoming IPsec packets, decrypts the encapsulated data packets, then passes the data packets to the local network. It also encrypts, encapsulates, and sends the IPsec data packets to the gateway at the other end of the VPN tunnel.

The IP address of a VPN gateway is usually the IP address of the network interface that connects to the Internet. You can also define a secondary IP address for the interface, and use that address as the local VPN gateway address, so that your existing setup is not affected by the VPN settings.

Once you have created the IPsec VPN topology, you can create managed and external gateways.
