Configure Lan Dmz Rules - NETGEAR ProSafe FVS318N Reference Manual

Configure LAN DMZ Rules

The LAN DMZ Rules screen allows you to create rules that define the movement of traffic
between the LAN and the DMZ. The default outbound and inbound policies are to block all
traffic between the local LAN and DMZ network. You can then apply firewall rules to allow
specific types of traffic either going out from the LAN to the DMZ (outbound) or coming in
from the DMZ to the LAN (inbound).
There is no drop-down list that lets you set the default outbound policy as there is on the LAN
WAN Rules screen. You can change the default outbound policy by allowing all outbound
traffic and then blocking specific services from passing through the wireless VPN firewall. You
do so by adding outbound service rules (see
page 152).
