QoS traffic limiting for AV update server

Hello,

We have recently deployed the XG appliance and had a ask about limiting the download bandwidth to our AV update server.

I have created a host entry for it, and then a rule based traffic shaping policy:

Policy Application - Rule

Rule Type - Limit

Priority 7

Limit 10240Kbps

Bandwidth Usage - Shared

I have then applied this to a policy:

Source - LAN, Networks - AV Server,  Service - HTTP, Destination - WAN, Networks - Any, Action - Accept, Traffic Shaping Policy - AV-Limited

I have then tested it by using a speed test program, but it still seems to get all the bandwidth.

I have reversed the Source/Destination settings but still no joy.

Have I missed something obvious?

Thanks in advance

Giles
