connected to the Internet via WAN1 (IP_230.100.100.1) on Firetunnel 30. Should
WAN1 fail, Outbound Fail Over tells Firetunnel 30 to reroute outgoing traffic to WAN2
(IP_213.10.10.2). Configuring your Firetunnel 30 for Outbound Fail Over provides a
more reliable connection for your outgoing traffic.
Please refer to appendix H for example settings.
2.3.2 Outbound Load Balancing
Outbound Load Balancing allows Firetunnel 30 to intelligently manage outbound
traffic based on the amount of load of each WAN connection.
In the above example, PC 1 (IP_192.168.2.2) and PC 2 (IP_192.168.2.3) are
connected to the Internet via WAN1 (IP_230.100.100.1) and WAN2
(IP_213.10.10.2) on Firetunnel 30. You can configure Firetunnel 30 to balance the
load of each WAN port with one of two mechanisms:
1. Session (by session/by traffic/weight of link capability)
2. IP Hash (by traffic/weight of link capability)
The IP Hash mechanism will ensure that the traffic from the same source IP address
and destination IP address will go through the same WAN port. This is useful for
some server applications that need to identify the source IP address of the client.
By balancing the load between WAN1 and WAN2, your Firetunnel 30 can ensure that
outbound traffic is efficiently handled by making sure that both ports are equally
sharing the load, preventing situations where one port is completely saturated by
outbound traffic.
