54 MultiCom Firewall User’s Manual
If you have a pre-existing router between the broadband access modem and the
MultiCom Firewall you will also need to use the Static IP Configuration option of
the Easy-Setup. The Firewall WAN IP address parameters must match the subnet
of your router and the router IP address should be the default gateway. Be sure to
enter in your ISP’s DNS information as well.

If you do not know this information check with your Internet Service Provider
support services or the documentation you received from them when you joined
them.
Plug & Play Configuration: DHCP
Here are the requirements necessary to install the MultiCom Firewall without
configuration.
1.
Is your Internet Service Provider giving you your IP address, DNS server
address and default firewall configuration with a DHCP server?
2. Are all of your internal network (LAN) devices configured as DHCP Clients?
If your Internet Service Provider uses DHCP to assign you your IP configuration
parameters and your computers are configured as DHCP clients you can simply
plug in the MultiCom Firewall immediately between your network and your
xDSL, cable or wireless modem. In this case it will automatically be a firewall
protecting your internal network (LAN) and enable all of your LAN computers to
use the same Internet account.
