Select all of the following options that correctly identify the primary role of an Internet Key Exchange (IKE) gateway in a site-to-site IPsec VPN configuration.

### Why this is right - **An Internet Key Exchange (IKE) gateway** is correct because it identifies the peer and the parameters used to negotiate the connection. - **An IPsec tunnel associated with a tunnel interface** is correct because it links the negotiated security association to a logical traffic interface. - **A static route for the remote local-area network (LAN)** is correct because the firewall needs a route that directs remote-network traffic into the tunnel. ### The concept A VPN configuration combines peer negotiation, tunnel protection, and routing. These functions are related but not interchangeable. The gateway describes how the firewalls find and authenticate each other. The IPsec tunnel protects traffic and is associated with a tunnel interface. The route determines which destinations use that tunnel. ### The other options - **D. A source Network Address Translation (NAT) rule that replaces the tunnel**: source translation is not a replacement for the VPN tunnel, gateway, or route. ### Terms - **IKE**: Internet Key Exchange. A protocol used to negotiate VPN security settings. - **IPsec**: Internet Protocol Security. Protocols that protect network traffic. - **NAT**: Network Address Translation. A method of changing network addresses. - **LAN**: Local-Area Network. A network serving devices at one site. ### Remember Negotiation, tunnel protection, and routing solve three different VPN configuration tasks.
