ProSafe VPN Firewall 200 FVX538 Reference Manual If you want to use a redundant ISP link for backup purposes, select the WAN port that will act as the primary link for this mode. Ensure that the backup WAN port has also been configured and that you configure the WAN Failure Detection Method to support Auto-Rollover. • Load Balancing Mode. In this mode the router distributes the outbound traffic equally among the WAN interfaces that are functional. Note: Scenarios could arise when load balancing needs to be bypassed for certain traffic or applications. Here the traffic needs to go on a specific WAN interface. This is done with the protocol binding rules of that WAN interface. The rule should match the desired traffic. For both alternatives, you must also set up Network Address Translation (NAT): • NAT. NAT is the technology which allows all PCs on your LAN to share a single Internet IP address. From the Internet, there is only a single device (the Router) and a single IP address. PCs on your LAN can use any private IP address range, and these IP addresses are not visible from the Internet. - The Router uses NAT to select the correct PC (on your LAN) to receive any incoming data. - If you only have a single Internet IP address, you MUST use NAT. NAT is the default setting. • Classical Routing. In this mode, the Router performs Routing, but without NAT. To gain Internet access, each PC on your LAN must have a valid Internet IP address. If your ISP has allocated many IP addresses to you, and you have assigned one of these addresses to each PC, you can choose Classical Routing. Or, you can use Classical Routing for routing private IP addresses within a campus environment. Otherwise, selecting this method will not allow Internet access through this Router. To learn the status of the WAN ports, you can view the Router Status screen (see "Viewing Router Configuration and System Status" on page 6-25) or look at the LEDs on the front panel (see "Router Front and Rear Panels" on page 1-6). Setting Up Auto-Rollover Mode If you want to use a redundant ISP link for backup purposes, ensure that the backup WAN port has already been configured. Then you select the WAN port that will act as the primary link for this mode and configure the WAN Failure Detection Method to support Auto-Rollover.
