Chapter 3 LAN Configuration This chapter describes how to configure the advanced LAN features of your ProSafe VPN Firewall 200, including the following sections: • "Choosing the Firewall DHCP Options" on page 3-1 • "Managing Groups and Hosts (LAN Groups)" on page 3-6 • "Configuring and Enabling the DMZ Port" on page 3-10 • "Static Routes" on page 3-12 Choosing the Firewall DHCP Options By default, the firewall will function as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, WINS Server, and default gateway addresses to all computers connected to the firewall LAN. The assigned default gateway address is the LAN address of the firewall. IP addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN. The DHCP options are available for both the LAN and DMZ settings. For most applications, the default DHCP and TCP/IP settings of the firewall are satisfactory. See the link to "Preparing a Computer for Network Access" in Appendix D, "Related Documents" for an explanation of DHCP and information about how to assign IP addresses for your network. If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the Enable DHCP server radio box by selecting the Disable DHCP Server radio box. Otherwise, leave it checked. Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the firewall's LAN IP address. Using the default addressing scheme, you should define a range between 192.168.1.2 and 192.168.1.100, although you may wish to save part of the range for devices with fixed addresses. The firewall will deliver the following parameters to any LAN device that requests DHCP: • An IP Address from the range you have defined. • Subnet Mask. • Gateway IP Address (the firewall's LAN IP address).
