Highlights of the release are our new multiWAN services: WAN Balancer and WAN Failover. Also included in this release is Ad Blocker, for filtering out banner advertisements. WAN Balancer allows companies to easily split traffic across up to six separate Internet connections. The traffic is spread based on user-specified weightings, ensuring less contention and higher performance. WAN Failover allows companies to prevent network downtime caused by their Internet Service Provider (ISP)." Read the rest of the release announcement for further information.
