2.6.1General VPN Setup

The following section discusses Virtual Private Networking with BiGuard 30.

2.6.1General VPN Setup

There are typically three different VPN scenarios. The first is a Gateway to Gateway setup, where two remote gateways communicate over the Internet via a secure tunnel.

100.100.100.1 200.200.200.1

192.168.2.x

Secure Tunnel

192.168.3.x

The next type of VPN setup is the Gateway to Multiple Gateway setup, where one gateway (Headquarters) is communicating with multiple gateways (Branch Offices) over the Internet. As with all VPNs, data is kept secure with secure tunnels.

100.100.100.1

201.201.201.1
	192.168.4.x

The final type of VPN setup is the Client to Gateway. A good example of where this can be applied is when a remote sales person accesses the corporate network over a secure VPN tunnel.

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 2.2.6 Management by IP or MAC address 2.2.7 DiffServ DSCP Marking2.2.8 DSCP Matching 2.3 Outbound Traffic2.3.1 Outbound Fail Over 192.168.2.2 1st ConnectionISP 2nd connection 192.168.2.32.4 Inbound Traffic 2.4.1 Inbound Fail OverBefore Fail Over After Fail Over2.4.2 Inbound Load Balancing Remote Access from Internet 2.5 DNS InboundHTTP ISP ISP 2.5.1 DNS Inbound Fail OverAfter Fail Over Before Fail OverDNS Request Heavy load on WANHeavy load on WAN DNS Reply2.6 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.

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 Appendix E Virtual Private Networking E.1 What is a VPN?E.2 What is IPSec?
