low network latencies to function properly. If bandwidth is being used by other applications such as an FTP server, users using VoIP will experience network lag and/or service interruptions during use. To avoid this scenario, this network has assigned VoIP with a guaranteed bandwidth and higher priority to ensure smooth communications. The FTP server, on the other hand, has been given a maximum bandwidth cap to make sure that regular service to both VoIP and normal Internet applications is uninterrupted

2.6 Virtual Private Networking
In the example above, the client is making a DNS request. The request is sent to the DNS server of BiGuard 30 through WAN2 1. WAN2 will route this request to the embedded DNS server of BiGuard 30 2. BiGuard 30 will analyze the bandwidth of both WAN1 and WAN2 and decide which WAN IP to reply to the request 3. After the decision is made, BiGuard 30 will route the DNS reply to the user through WAN2 4. The user will receive the DNS reply with the IP address of WAN1 5. The browser will initiate an HTTP request to the WAN1 IP address 6. The HTTP request will be send to BiGuard 30’s URL Host Map 7. The Host Map will then redirect the HTTP request to the HTTP server 8. The HTTP server will reply 9. The URL Host Map will route the packet through WAN1 to the user 10. Finally, the client will receive an HTTP reply packet

D.3 Firewall Basics
D.3.1.1 Stateful Packet Inspection
With a LAN connected to the Internet through a router, there is a chance for hackers to access or disrupt your network. A simple NAT router provides a basic level of protection by shielding your network from the outside Internet. Still, there are ways for more dedicated hackers to either obtain information about your network or disrupt your network’s Internet access. Your BiGuard 30 provides an extra level of protection from such attacks with its built-in firewall
