Hello,
I'm not having any success getting an ASG 120 (7.103) to correctly modify IP HEADERS and set the DSCP bits. Here is what I am attempting to accomplish:
1. My Polycom Phones tag their SIP and RTP traffic w/ 0x2e (EF - Expedited Forwarding) bits in the IP header field. We can clearly see the IP header being tagged by the phone via TCPdump on the Astaro.
2. I want to tag all packets going BACK to the IP range for the phones w/ the same DSCP bit. So we enabled QOS on the External and Internal interfaces, and created a traffic selected that states Any Source -> Any Protocol -> Destination Phone Network should have DSCP bits set.
On looking at the packet trace, the Astaro is not modifying the DSCP field in the IP header. It reads 0x00.
Anyone have any luck with this?
