ProSafe VPN Firewall 200 FVX538 Reference Manual Inbound Traffic Incoming traffic from the Internet is normally discarded by the firewall unless the traffic is a response to one of your local computers or a service that you have configured in the Inbound Rules menu. Instead of discarding this traffic, you can have it forwarded to one or more LAN hosts on your network. The addressing of the firewall's dual WAN port depends on the configuration being implemented: Table C-1. IP addressing requirements for exposed hosts in dual WAN port systems Configuration and WAN IP address Single WAN Port (reference case) Inbound traffic • Port forwarding • Port triggering • DMZ port Fixed Dynamic Allowed (FQDN optional) FQDN required Dual WAN Port Cases Rollover FQDN required FQDN required Load Balancing Allowed (FQDN optional) FQDN required Inbound Traffic to Single WAN Port (Reference Case) The Internet IP address of the 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 (Figure C-4), the WAN's Internet address is either fixed IP or a fullyqualified domain name if the IP address is dynamic. Router WAN IP netgear.dyndns.org IP address of WAN port: FQDN is required for dynamic IP address and is optional for fixed IP address Figure C-4 Inbound Traffic to Dual WAN Port Systems The IP address range of the 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.
