Installing the Network Interface Cards
The number of network interface cards (NICs) required depends on the installation method selected as
described in this section.
Inline
The inline installation of Sentriant AG, where the MS and ES are installed on a single server, requires
two network interface cards (NICs) installed for Sentriant AG to operate properly.
The inline installation of Sentriant AG 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).
