The Vpn Connection Screen - ZyXEL Communications ZyWall USG20-VPN User Manual

• In any VPN connection, you have to select address objects to specify the local policy and remote
policy. You should set up the address objects first.
• In a VPN gateway, you can select an Ethernet interface, virtual Ethernet interface, VLAN
interface, or virtual VLAN interface to specify what address the USG uses as its IP address when
it establishes the IKE SA. You should set up the interface first.
• In a VPN gateway, you can enable extended authentication. If the USG is in server mode, you
should set up the authentication method (AAA server) first. The authentication method specifies
how the USG authenticates the remote IPSec router.
• In a VPN gateway, the USG and remote IPSec router can use certificates to authenticate each
other. Make sure the USG and the remote IPSec router will trust each other's certificates.
