4.4.9.2 Dynamic DNS

The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful when hosting servers via your WAN connection, so that anyone wishing to connect to you may use your domain name, rather than having to use a dynamic IP address that changes periodically. This dynamic IP address is the WAN1/WAN2 IP address of the router, which is assigned to you by your ISP. Click Edit in the Dynamic DNS Settings Table to set related parameters for a specific interface.

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 policies for different PCs on the network. Policy based traffic shaping lets you better manage your bandwidth, providing reliable Internet and network service to your organization 2.2.7 DiffServ DSCP Marking 2.2.6 Management by IP or MAC address2.3 Outbound Traffic 2.2.8 DSCP Matching2.3.1 Outbound Fail Over ISP 2nd connection 1st Connection192.168.2.2 192.168.2.32.4.1 Inbound Fail Over 2.4 Inbound TrafficAfter Fail Over Before Fail Over2.4.2 Inbound Load Balancing 2.5 DNS Inbound Remote Access from InternetHTTP 2.5.1 DNS Inbound Fail Over ISP ISPBefore Fail Over After Fail OverHeavy load on WAN Heavy load on WANDNS Request DNS ReplyIn 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 2.6 Virtual Private NetworkingBiGuard Client 2.6.1 General VPN SetupAfter Fail Over Before Fail Over2.6.2 VPN Planning - Fail Over BiGuard Before Fail Over3.2 Before You Begin 3.1 OverviewChapter 3 Getting Started 3.3 Connecting Your Router 3.4.1 Overview 3.4 Configuring PCs for TCP/IP Networking3.4.2 Windows XP 3.4.2.1 Configuring 1.

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 E.2 What is IPSec?
