ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G Reference Manual • Auto-Rollover Mode. The selected WAN interface is made primary and the other is the rollover link. As long as the primary link is up, all traffic is sent over the primary link. Once the primary WAN interface goes down, the rollover link is brought up to send the traffic.Traffic will automatically roll back to the original primary link once the original primary link is back up and running again. 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. The VPN firewall 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. If certain traffic needs to travel on a specific WAN interface, configure protocol binding rules for that WAN interface. The rule should match the desired traffic. • Single WAN Port Mode. The selected WAN interface is made primary and the other is disabled. For whichever WAN mode you choose, you must also choose either NAT or classical routing, as explained in the following sections. Network Address Translation Network Address Translation (NAT) allows all PCs on your LAN to share a single public Internet IP address. From the Internet, there is only a single device (the VPN firewall) 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 VPN firewall uses NAT to select the correct PC (on your LAN) to receive any incoming data. • If you only have a single public Internet IP address, you MUST use NAT. (the default setting). • If your ISP has provided you with multiple public IP addresses, you can use one address as the primary shared address for Internet access by your PCs, and you can map incoming traffic on the other public IP addresses to specific PCs on your LAN. This one-to-one inbound mapping is configured using an inbound firewall rule. Connecting the FVS336G to the Internet v1.0, March 2009 2-11
