ISP
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 MH-1000. You can configure MH-1000 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 MH-1000 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.
Please refer to appendix D for example settings.
2.4 Inbound Traffic
Learn how MH-1000 can handle inbound traffic in the following section.
2.4.1 Inbound Fail Over
Configuring MH-1000 for Inbound Fail Over allows you to ensure that incoming traffic is uninterrupted by
having MH-1000 default to WAN2 should WAN1 fail.
