Type an unassigned IP address from the secondary network.When you type IP addresses, type all the numbers and the stops. Do not use the TAB or arrow key.5 Click OK. Click OK again.NoteBe careful to add secondary network addresses correctly. Policy Manager does not tell you if the addressis correct. We recommend that you do not create a subnet as a secondary network on one interface thatis a component of a larger network on a different interface. If you do this, spoofing can occur and thenetwork cannot operate correctly.Adding WINS and DNS Server AddressesA number of the features of the Firebox® must have shared Windows Internet Name Server (WINS) andDomain Name System (DNS) server IP addresses. These features include DHCP and Remote User VPN.Access to these servers must be available from the trusted interface of the Firebox.This information is used for two purposes:• The Firebox uses the DNS server shown here to resolve names to IP addresses for IPSec VPNs andfor the spamBlocker, GAV and IPS features to operate correctly.• The WINS and DNS entries are used by DHCP clients on the trusted or optional networks, MUVPNusers, and PPTP RUVPN users to resolve DNS queries.User Guide 107
