1.4 Installing the Network Interface Cards

The number of network interface cards (NICs) required depends on the installation method selected
as described in this section.

1.4.1 Inline

The inline installation of Novell ZENworks Network Access Control, where the MS and ES are
installed on a single server, requires two network interface cards (NICs) installed for Novell
ZENworks Network Access Control to operate properly.
The inline installation of Novell ZENworks Network Access Control where the MS and ES are
installed on different servers requires at least three NICs; one for the MS and two for each ES.
The inline installation interfaces form a bridge from one part of your network to another as shown in
®
the following figure. The Linux operating system assigns each interface a name (for example,
eth0, eth1, and so on). It is very important that you connect the eth0 interface to your local area
network (LAN) side, and eth1 to the Virtual Private Network (VPN) side (for inline mode or for
the main DHCP server in DHCP mode).

1.4.2 DHCP

A DHCP installation requires two NICs where the MS and ES are installed on the same server (see
Figure 1-10), and at least three NICs where the MS and ES are installed on different servers; one for
the MS and two for each ES.
