Virtual in-path network topologies in which the LAN-bound traffic traverses the WAN interface might require that you configure the SteelHead to bypass LAN-bound traffic so that it is not subject to the maximum root bandwidth limit. Some deployment examples are WCCP or a WAN-side default gateway. The LAN bypass feature enables you to exempt certain subnets from QoS enforcement. You can configure LAN bypass on both inbound and outbound QoS.

For information about LAN bypass, see the SteelHead Management Console User’s Guide.

Because xx50 SteelHeads follow performance guidelines but do not have enforced limits, you do not need to configure LAN bypass on these models.
