10 Chapter 1: Intr oduction 1.1 Overview Congratulations on purchasing BiGuard 2/10 Router from Billion. Combining a router with an Ethernet network switch, BiGua rd 2/10 is a state-of -the-art device that provides ev erything y ou need to get your network connected to the Internet over your Cable or DSL connection quickly and easily .
11 1.2.3 Intelligent Bandwidth Manage ment BiGuard 2/10 u tilizes Quality of Service (QoS) to give you full control over the priority of both incoming and outgoing d ata, ensuring that critica l data such as customer informat ion moves thr ough your net work, even while under a heav y load.

16 Chapter 2: Router Applications 2.1 Overview Y o ur BiGuar d 2/10 R outer is a versa tile device that can be configured to not o nly protect your network from malicious attackers, but also ensure optimal usage of available bandwidth with Quality of Servic e (QoS).
17 2.2.2 Q oS Policie s for Differ ent Applicatio ns By setting different QoS policies accordin g to the applicati ons yo u are r unning, you can use BiGuard 2 /10 to optimize the bandwidth tha t is being used on y our network.
18 As illustrated in the diagram above, applicat ions such as V o iceover IP (V oIP) require low network latencies to fu nction properly . If bandwidth is being used by other applications such as an FTP server , user s using V oIP will experience network lag and/or service interr uptions during use.
19 2.2.4 Policy Ba se d Traffic Shaping Policy Based T raffic Shaping allows you to apply specific traffic policies across a range of IP addresses or ports. This is particularly useful for a ssigning different policies for diff erent PCs o n the network .
20 2.2.6 Management by IP or MAC address BiGuard 2/10 can also be configured to appl y traffic policies based on a particular IP or MAC address. This allows you t o quickly assign different traffic policies to a specific computer on the network.
21 2.2.7 DiffServ (DSCP Marking) DiffServ (a.k.a. DSCP Marking) allows y o u to classify tr affic based on IP DSCP v alues. Thes e markin gs can be used to identify traffic w ithin the netw ork. O ther inte rface s can ma tch traffic based o n the DSCP mark ings.
22 secure tunnel. The next t ype of VPN setup is the Gateway to Mu ltiple G ateway setup, where one gateway (Headquarter) is communicat ing with multiple gateways (Br anch Offices) over the Int ernet. As wit h all VPNs, data is ke pt secure with secure t unnels.

135 Appendix D: Network, R outing, an d Firewa ll Basics D.1 Network Basics D.1.1 IP Addresses With the number of TCP/IP networks interconne cted across the globe, ensuring that transmitted data reache s the correct destination requires each computer on the Internet has a uniqu e identifier .
136 192.168.234.245/24, which means that the net mask is 24 ones followed by 8 zeros. (11111111 11111111 11111111 000 00000). D.1.1.2 Subnet Addressing Subn et address ing enables the spli t of one IP network address into multiple physical networks.
137 D.1.2 Network Address Translat ion ( NAT) T raditionally , multiple PCs that needed simu ltaneous Internet access also required a range of IP addresses from the Internet Se rv ice Provider (ISP). Not only was th is method very costly , but the number of a vailable IP addresses for PCs is limited.
138 connected to at least two networks. Usually , this is a LAN and a WAN that is connected to an ISP network. R outers are located at gatew ays, the places where two or more net works connect.
139 firewall adds features t hat deal with outside Internet intrusion and attacks. When an attack or intrusion is detected, the firewa ll can be configured to log the in trusion attemp t, and c an also notify th e admin istrato r of the in cident. With this informatio n, the administrator can work with the ISP to take action agai nst the hacker .
140 Appendix E: Virtua l Private Netw orking E.1 What is a VPN? A Virtual Privat e Network (VPN) is a sh ared network where pr ivate data is segmented from other tr affic so that only the intended recipient has access. It allows org anizations to securely transmit data over a public medium like the Internet.
141 Internet Protocol Securit y (IPSec) is a set of protocols and algorithms that provide data authentication, integrity , and confiden tialit y as data is transferr ed across IP networks. IPSec provides data se curity at the IP packet level, and protects against possible security risks by protecting data.
142 A typical AH packet looks like this: E.2.1.2 Encapsulating Se curity Payload (ESP) Encapsulating Security P ayload (ESP) provid es privacy f or data through encrypt ion. An encryption algorithm combines the da ta with a key to encrypt it. It then repackages the data using a special format , and tr ansmits it to the destination.
143 like this: E.2.1.3 Security Associations (SA) Security Associations are a one- way relationships bet ween sender and receiver that specify IPSec-related par ameters.
144 Tr a n s p o r t M o d e : - This mode is used to provide data se curity be tween t wo netw orks . It provid es protection for the entire IP pack et and is sent by adding an out er IP header corresponding to the two tunnel end-points.
145 E.2.5 Internet Key Exc hange (IKE) Before either AH or ESP can be use d, it is necessary for the two communication devices to exchange a secret key that the security protocols themselv es will use. T o do this, IPSec uses Internet K ey Exchange (IKE) as a primary support protocol.
