Chapter 4 - Firewall Software

In the configuration shown in Figure 4-3, the Firewall is connected to the Secured (private) LAN

via the LAN 1 connection of the back of the unit. The Internet (public) LAN is connected to the

LAN 2 connector on the back of the unit. Connection to the Internet is then provided by a T1 DSU

connected to the RS232/V.35 connector on the back of the unit.

During the loading of the Firewall software, the Secured LAN Port Parameters group (in the IP

Setup dialog box) was configured to include an unregistered IP Address of 192.168.0.101 and

default Net Mask of 255.255.255.0 for the private LAN (LAN 1).

The Internet LAN Port Parameters group is either configured with the DHCP Client option

active, enabling the ISP to dynamically provide the registered Internet IP addresses, or with the

DHCP Client option disabled if a static IP addressing scheme is provided by the ISP. If the DHCP

Client field is deactivated the static IP Address of 204.26.12.10 is then entered and the WAN

option is checked in the Internet Gateway Parameters group.

In the Default WAN Link Setup dialog, the WAN Enable option is activated.

In the Dial Number field, the number for the ISP is entered and in the User Name and

Password fields, the user name and password agreed upon with the ISP are entered.

The sections that follow provide examples of how to add some of the advanced features that

enhance and build upon this basic setup.
