Setting Up Auto-Rollover Mode - NETGEAR FVX538 - ProSafe VPN Firewall 200 Router 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
Configuration and System Status" on page
"Router Front and Rear Panels" on page

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.
