Chapter 11 Firewall Screens " The ordering of your rules is very important as rules are applied in the order that they are listed. • When the ZyWALL is in bridge mode, enable the default WAN to LAN firewall rule for the BOOTP_CLIENT service to let DHCP clients behind the ZyWALL use a DHCP server on the WAN. • Enable the default WAN to LAN firewall rule for the NetBIOS service to let computers behind the ZyWALL access devices on the WAN using computer names. Figure 132 SECURITY > FIREWALL > Rule Summary The following table describes the labels in this screen. Table 50 SECURITY > FIREWALL > Rule Summary LABEL DESCRIPTION Packet Direction Use the drop-down list boxes and click Refresh to select a direction of travel of packets for which you want to display firewall rules. +/Default Policy Note: The VPN connection directions apply to the traffic going to or from the ZyWALL's VPN tunnels. They do not apply to other VPN traffic for which the ZyWALL is not one of the gateways (VPN pass-through traffic). In the heading row, click + to expand or - to collapse the Source Address, Destination Address and Service Type drop down lists for all of the displayed rules. This field displays the default action you selected in the Default Rule screen for the packet direction displayed. ZyWALL 2 Plus User's Guide 203
