QoS on ASA

farkascsgy · ‎12-10-2007

Hello,

My question is the following: what occurs first the NAT or QoS. I am going to implement QoS on my firewall, Voice traffic goes trough it and I want to catch the voice traffic with ACL.

Policy for outside interface.

permit traffic from Internal network(private address) to Public server (Provider's PBX) (public address)

Policy for DMZ (traffic coming from OUTSIDE to DMZ)

Publicly hosted server (public address of the Provider's PBX) to Internal address of my PBX?

Please correct me if I am wrong...

Thanks.

Hi, the QoS process is at the end. When the first packet arrives on the ingress interface the packet is route to the right outgoing interface. During this flow al rules and actions associated with this packet and flow are processed. Then it arrivess at the QoS engine. And put on the wire.
