Symptoms

TCP flows going through the IP forwarding and L2 forwarding virtual server might get very low bandwidth.

Impact

Lower throughput than expected.

Conditions

-- BWC policy applied. -- TCP traffic passes through the IP forwarding or L2 forwarding virtual server.

Workaround

When using BWC, use a proxy virtual server instead of IP forwarding or L2 forwarding virtual servers.

Fix Information

TCP flows going through the IP forwarding and L2 forwarding virtual server no longer affect bandwidth.
