NETGEAR UTM5-100NAS, UTM50-100NAS manual Setting LAN DMZ Rules

ProSecure Unified Threat Management (UTM) Appliance Reference Manual

Setting 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 allow all traffic between the local LAN and DMZ network. You can then apply firewall rules to block specific types of traffic from either going out from the LAN to the DMZ (outbound) or coming in from the DMZ to the LAN (inbound).

There is no pull-down menu 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 blocking all outbound traffic and then enabling only specific services to pass through the UTM. You do so by adding outbound services rules (see “LAN DMZ Outbound Services Rules” on page 5-20).

To access the LAN DMZ Rules screen:

1.Select Network Security > Firewall from the menu. The Firewall submenu tabs appear.

2.Click the LAN DMZ Rules submenu tab. The LAN DMZ Rules screen displays.
