ProSecure Unified Threat Management (UTM) Appliance Reference Manual

See “Virtual Private Networks (VPNs)” on page B-9 for more information about the IP addressing requirements for VPNs in the dual WAN modes. For information about how to select and configure a dynamic DNS service for resolving FQDNs, see “Configuring Dynamic DNS” on page 3-19. For information about WAN mode configuration, see “Configuring the WAN Mode (Required for Dual-WAN Port Models Only)” on page 3-9.

The diagrams and table below show how the WAN mode selection relates to VPN configuration.
