Inbound Traffic To A Single Wan Port System; Inbound Traffic To A Dual Wan Port System - NETGEAR FVS336Gv3 Reference Manual

ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3

Inbound Traffic to a Single WAN Port System

The Internet IP address of the VPN firewall's WAN port must be known to the public so that
the public can send incoming traffic to the exposed host when this feature is supported and
enabled.
In the single WAN case, the WAN's Internet address is either a fixed IP address or an FQDN
if the IP address is dynamic.
Figure 16. Inbound traffic to a single WAN port system

Inbound Traffic to a Dual WAN Port System

The IP address range of the VPN firewall's WAN port must be both fixed and public so that
the public can send incoming traffic to the multiple exposed hosts when this feature is
supported and enabled.
Inbound Traffic: Dual WAN Ports for Improved Reliability
In a dual WAN port auto-rollover configuration, the WAN port's IP address always changes
when a rollover occurs. You must use an FQDN that toggles between the IP addresses of the
WAN ports (that is, WAN1 or WAN2).

Inbound Traffic: Dual WAN Ports for Load Balancing
In a dual WAN port load balancing configuration, the Internet address of each WAN port is
either fixed if the IP address is fixed or an FQDN if the IP address is dynamic (see the
following figure).
