Local Encryption Domain
The local encryption domain defines the internal networks accessible by encrypted traffic from remote sites
and networks, that traffic from them to remote sites is encrypted. By default, the local encryption domain is
determined automatically by the appliance. Networks behind LAN interfaces and trusted wireless networks
are part of the local encryption domain. Optionally, you can manually create a local encryption domain
instead. See the VPN > Site to Site Advanced page for instructions.
