16 1.3.4 Cabling Most Ethernet netw orks currently use unshielded twist ed pair (UTP) cabling. The UTP cable contains eigh t conductors, arranged in fou r twisted pairs, and terminated with an RJ45 t ype connector . One of the most common causes of networking problems is bad cabling.
17 Chapter 2: Router Applications 2.1 Overview Y our BiGuard 50G router is a vers atile device that can be configured to not only protect your network from maliciou s attackers, but also ensure optimal usage of available bandwidth with Quality of Service (QoS) and both Inbound and Outbound Load Balancing.
18 2.2.2 QoS Policies for Different Applications By setting differen t QoS policies according to the application s you are running, you can use BiGuard 50G to optimiz e the bandwidth that is being used on your network.
19 applications such as an FTP server , users using VoIP will experience network lag and/or service interruption s during use. T o avoid this scenario, this network has assigned V oIP with a guaranteed bandwidt h and higher priori ty to ensure smooth communications.
20 manage your bandwidth, providing reliable Internet and network service to your organization. 2.2.5 Priority Bandwidth Utilization Assigning priority to a certain service allows BiGuard 50G to give either a higher or lower priority to traffic from this particular servic e.
21 2.2.6 Management by IP or MAC address BiGuard 50G can also be configured to appl y traffic policies based on a particular IP or MAC address. This allows you to qu ickly assign different traffic policies to a specific computer on the network. DiffServ (DSCP Marking) DiffServ (a.
22 Other interfaces can match tr affic based on the DSC P markings. DSCP markings are u s e d t o d e c i d e h o w p a c k e t s s h o u l d b e t r e a t e d , a n d i s a u s e f u l t o o l t o g i v e precedence to varying types of data.
23 In the above example, PC 1 (IP_192.168. 2 .2) and PC 2 (IP_192.168.2.3) are connected to the Internet via W AN1 (IP_230.100.100.1) on BiGuard 50G. Should WAN1 fai l, Outbound F ail Over tells BiGuard 50G to reroute outgoing tr affic to WAN2 (IP_213.
24 connected to the Inter net via WAN1 (IP_23 0.100.100.1) and WAN2 (IP_213.10.10.2) on BiGuard 50G. Y ou can configure BiGuard 50G to balance the load of each WAN port with one of two mechanisms: 1. Session (by session/by traffic/weight of link capability) 2.
25 2.4.1 Inbound Fail Over Configuring BiGuard 50 G for Inbound F ail Over allows you to ensure that incoming traffic i s uninterrupted by having BiGuar d 50G default to W AN2 should WAN1 fail. In the above example, an FTP Server (IP_192.168.2.2) and an HT TP Server (IP_192.
26 2.4.2 Inbound Load Balancing Inbound Load Balancing allows BiGuard 50G to intelligently man age inbound traffic based on the amount of load of each W AN connection. In the above example, an FTP server (IP_192.168.2.2 ) and an HT TP server (IP_192.168.
27 2.5 DNS Inbound Using DNS Inbound is a great way to int elligently direct netw ork traffic. DNS Inbound is a three step process. First, a DNS request is made to the router via a remote PC.
28 2.5.1 DNS Inbound Fail Over BiGuard 50G can be configured to reply the WAN2 IP address for the DNS domain name request should W AN1 fail. In the above example, an FTP Server (IP_192.168.2.2) and an HT TP Server (IP_192.168.2.3) are connected to the In ternet via W AN1 (IP_200.
29 2.5.2 DNS Inbound Load Balancing DNS Inbound Load Balancin g allows BiGuard 50G to intell igently manage inbound traffic based on the am ount of load of each WAN conne ction by assigning the IP address with the lowest traffi c load to incoming request s.
30 In the example above, the client is making a DNS reques t. The request is sent to the DNS server of BiGuard 50G throu gh WAN2 (1). W AN2 will rou te this request t o the embedded DNS server of BiGuard 50G (2). BiGuard 50G will an alyze the bandwidth of both WAN1 and WAN2 and decide wh ich WAN IP to reply to the requ est (3).
31 2.6 Virtual Private Networking A Virtual Priv ate Network (VPN) enables y ou to send data between two computers across a shared or public network in a ma nner that emul ates the properties of a point-to-point private link. As such, it is perfect for connecting br anch offices to headquarters across the Intern et in a sec ure fashion.
32 VPN provides a flexible, cost-efficien t, and reliab le way for companies of all sizes to stay connected. One of the most important steps in setting up a VPN is proper planning. The followi ng sections demonstrate the various wa ys of using BiGuard 50G to setup your VPN.
33 gateway usi ng WAN1 through a secure VPN tunnel. Should W AN1 fail, outbound traffic from BiGuard 50G will automatically be redirected to WAN2. This process is completely tr ansparent to the remote gatewa y , as BiGuard 50G will automatically update the domain name (biguard.
34 2.6.3 Concentrato r The VPN Concentrator provides an easy way for br anch offices to connect to headquarter through a VPN tunnel . All branch office tr affic will be redirected to the VPN tunnel to headquarter with the ex ception of LAN-side traffi c.

165 Appendix D: Network, Routing, and Firewall Basics D.1 Network Basi cs D.1.1 IP Addresses With the number of T CP/IP networks interconnected across the globe, ensuring that transmitted data reaches the correct dest ination requires each computer on the Internet has a unique ident ifier .
166 back slash (/). F or example, a typical Class C address could be written as 192.168.234.245/24, which means th at the net mask is 24 ones followed by 8 zeros. (11111111 11111111 11111111 00000000). D.1.1.2 Subnet Addressing Subnet addressing enables th e split of one IP network address into mu ltiple physical networks.
167 from these ra nges. D.1.2 Network Address Translation (NAT) T raditionally , mult iple PCs that needed simult aneous Intern et access also required a range of IP addresses from the Internet Service Prov ider (ISP). Not only was th is method very costly , but th e number of available IP addresses for PCs is limited.
168 D.2 Router Basics D.2.1 What is a Router? A router is a device that forwards da ta packets along networks. A router is connected to at least t wo networks. Usua lly , this is a LAN an d a WAN that is connected to an ISP network. Routers ar e located at gateways, the places where two or more networks connect.
169 D.3 Firewall Basi cs D.3.1 What is a Firewall? Firewalls prevent unaut horiz ed Internet users from accessing private networks connected to the Internet. All messages en tering or leaving the in tranet pass through the f irewall, which examines each message and blocks those that do not meet the specified security criteria.
170 D.3.2 Why Use a Firewall? With a LAN connected to the Internet throug h a router , there is a chance for hackers to access or disrupt your network. A simp le NA T rou ter provides a basic level of protection by shield ing your network from the out side Internet .
171 Appendix E: Virtual Private Networking E.1 What is a VPN? A Virtual Private Network (VPN) is a shared network where private data is segmented from other traffic so that only the intended recipient has access. It allows organization s to securely transmit data over a public medium like the Internet.
172 data authentication, in tegrity , and confiden tiality as data is tr ansferred across IP networks. IPSec provides data security at the IP packet level, an d protects against possible security risks by pr otecting data. IPSec i s widely used to establish VPNs.
173 E.2.1.2 Encapsulating Security Payload (ES P ) Encapsulating Security P ayload (ESP) provid es priv acy for data through encryption. An encryption algorithm combi nes the data with a key to encry pt it. It then repackages the data using a specia l format, and transmits i t to the destination.
174 E.2.1.3 Security Associations (SA ) Security Associations are a one-way relationsh ips between sender and receiver th at specify IPSec-related parameters. They provide data protection by using the defined IPSec protocols, and allow organizati ons to control according to the security policy in effect, which resou r ces may communicate securely .
175 T ransport Mode - This mode is used to provide data se curity between two networks. It provides p r o t e c t i o n f o r t h e e n t i r e I P p a c k e t a n d i s s e n t b y a d d i n g a n o u t e r I P h e a d e r corresponding to the two tunnel end-points.
176 E.2.4 Tunnel Mod e ESP Here is an example of a packet with ESP applied: E.2.5 Internet Key Exchange (IKE) Before either AH or ESP can be used, it is necessary for the two communication devices to exchange a secret key that the security prot ocols themselves will use.
177 addresses. Aggressive mode reduces this process to three messages, but par ameter negotiation is limited, i dentity protection is lack ing except when using public key encryption, and is more vulnerable to Denial of Service attacks. Phase II, known as Quick Mode, est ablishes symmetrical IPSec Security Associations for both AH and ESP .
178 Appendix F: IPSec Logs and Events F.1 IPSec Log Event Categories There are three major categories of IPSe c Log Events for your BiGuard 50G. These include: 1.
179 Received Main mode second message of ISAKMP Received the second message of main mode. Done to exchange key values. Send Main mode second response message of ISAKMP Sending the main mode second response message. Done to exchange key val ues. Received Main mode second response message of ISAKMP Received the main mode second response message.
180 Received Aggressive mode second ISAKP Message Received the second message of aggressive mode. Done to exchange proposal and key values. Send Quick mode init ial message Sending the first message of quick mode (Phase II). Done to exchange proposal and ke y values (IPSec).
