Using the VPN Firewall as a DHCP Server
By default, the VPN 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 LAN. The assigned default gateway address is the LAN address of the
VPN firewall. IP addresses will be assigned to the attached PCs from a pool of addresses that you
must specify. Each pool address is tested before it is assigned to avoid duplicate addresses on the
LAN.
For most applications, the default DHCP and TCP/IP settings of the firewall are satisfactory. See
the link to “TCP/IP Networking Basics” in Appendix C, “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.
