20 Getting Started
Rackmounting the BiGuard S10
Follow the steps below to install the BiGuard S10 in a rack case.
1. Align one bracket with the holes on one side of the BiGuard S10 and secure it with the
bracket screws.
2. Repeat step 1 to attach the other bracket.
3. After attaching both mounting brackets, position the BiGuard S10 in the rack by lining up
the holes in the brackets with the appropriate holes in the rack.
4. Secure the BiGuard S10 to the rack with the remaining rack-mounting screws.

Setting up the BiGuard S10 21
Connecting to a WAN
Connect an RJ-45 Ethernet cable to the WAN port on the BiGuard S10, connect the other end to
an ADSL modem, cable modem, or another router.

Connecting power
Connect the power adapter cable to the DC 12V connector on the BiGuard S10. Connect the
power adapter to an electrical outlet.
FIGURE 4 CONNECTING THE POWER ADAPTER
Turning on the power and checking LED status
Press the power switch on the rear of the BiGuard S10. The LEDs all blink once. The LEDs blink
in sequence from LAN to WAN. Then all LEDs blink once again. In about thirty (30) seconds, the
status LED turns off to indicate the system is operational.

Network deployment/applications 23
Network deployment/applications
The purpose of this section is to help you set up the BiGuard S10 device in your network, and to
introduce the different networking environment scenarios available to you for designing the lay-
out and connectivity of your organization's network.
Before starting to configure the BiGuard S10 for your network, you need to decide on the num-
ber of devices that you will need and to choose the type of functionality (router, firewall, or gate-
way) that they will use. The number of devices that you need to configure depends on the
number of networks you want to interconnect, the type of network connection, and on the level
of activity on the connected networks.
The following illustrations represent real-world network deployment examples, SSL VPN Appli-
cations, and SSL VPN Features for the use of the BiGuard S10 for easy integration of the
BiGuard S10 into your existing network.
Network environment scenarios
The following tables show different scenarios for deploying the BiGuard S10.
All in one solution: firewall, remote and Internet access
The BiGuard S10 provides the ideal solution for secure remote access to corporate networks,
small branch offices and small/medium sized businesses. The BiGuard S10 also provides Inter-
net access and firewall functionality for the organization. A typical setup for users and small
businesses alike is to have a single BiGuard S10 device connected to the Internet as a secure
gateway to provide an all-in-one secure remote and Internet access solution.

Installing behind a gateway/firewall
The BiGuard S10 can be successfully placed behind any well established network and firewall
infrastructure to provide a secure remote access solution to the organization with minimal
changes to your existing network topology.
FIGURE 6 BEHIND AGATEWAY/FIREWALL
Fitting into a DMZ zone behind an existing firewall router
The following illustration demonstrates how the BiGuard S10 can be connected to the DMZ
zone of an existing firewall router to provide secure remote access to the servers in the office.

Network deployment/applications 25
All in one: public servers on DMZ zone, private servers on LAN
The BiGuard S10 above is configured to support secure remote access, firewall and internet
access functionality. Public servers are placed on DMZ zone while private servers for secure
remote access are placed on the LAN side.
