# Example VPN configuration 2: define a site for the external VPN gateway

The External VPN Gateway element needs a Site element.

## Before you begin

2. (Optional) In the Name field, enter a descriptive name for the site.
3. Select or create the elements that represent the protected IP addresses behind the Gateway in the left pane, then click Add to include them.

VPN | Shows the VPNs where this site is used.
Enable | When selected, the site is enabled in the specified VPN.
Mode | Defines the mode for the Site for each VPN in which it is enabled. Normal — Use this mode for all active Site elements that do not require one of the other two modes. Private — (VPN Gateways on Security Engines only) Use this mode for the local untranslated addresses when addresses are translated using NAT in the VPN. You must include the translated IP addresses (the addresses that the other end sees) as a Normal-mode Site element in these types of VPNs. If NAT is disabled in the VPN, any Sites in the Private mode are ignored. Hub — Use this mode on a hub gateway in tunnel-to-tunnel forwarding. Hub mode Sites contain the IP addresses of the networks that are behind the remote spoke gateways (the networks between which the hub gateway forwards traffic). The automatically generated Site cannot be used as a Hub Site.
