3.4 Connecting Multiple ISP Links

The standard option for increasing the bandwidth of your WAN link is to upgrade the
capacity of the existing link. However, usually this option will come at a high price in both
time and money. And sometimes it may not be available at all. Thus, ZyWALL 1050/ZyWALL
USG 300 comes with another solution which gives more flexibility on upgrading your WAN
Link. Basically, ZyWALL can build up to 12 PPPoE WAN links via one single port or having
multiple fixed links over four physical ports. Moreover, ZyWALL 1050/ZyWALL USG 300
supports an easy management feature for all your WAN Links. It will create a "WAN Trunk"
interface for you to manage all of your WAN links. You can manage it like a single WAN link.
Users are allowed to choose a load balancing algorithm they wish in order to optimize the
utilization of the WAN Links as well as the fault tolerance to increase reliability.
