We have an ASG220 at our main office on a 6M/6M connections and the RED device at a remote office on a 1.5M/1.5M connection. Our highest priority service is VOIP, which we are using a DSCP tag of 46 to mark the VOIP packets.
Outbound QoS form the ASG220 WAN interface seems to be working fine.
The issue is the traffic inbound from the RED. If we enable QoS on the RED interface, the bandwidth for all services instantly gets cut in half or worse, even before we setup any selectors or pools.
