Hello, I inherited a network with 4 sites connected together via 3 PA-500's and a PA-2020. We have implemented Lync for VOIP and I'm having issues getting packets to retain their tags across the VPN (internal to the tunnel is all I want) I can't seem to find any documentation talking about DSCP/COS/IP Precedence tags anywhere in the documentation/forum posts. I see stuff about Traffic shaping (Palo Alto calls this "QOS" but it's not what I'm needing) I have called Tech support looking for an answer to this, however every time I get blank answers along the lines of "what is DSCP" or "what you want is QOS, goto... " that ends up being the traffic shaping stuff. Any help is appreciated. Thanks.
