I have a WebEx Server hosted behind a PA FW. I need to apply QoS for it. Currently, I have a NAT in place to NAT the WebEx Public IP to the Server Private IP, Destination NAT is applied. Is it applicable to apply QoS for such traffic? I need to ensure WebEx stability despite the utilization.
It would only work for users on the inside of your network. Any QoS tags on a packet are stripped by the ISP and internet routers. So you can QoS your internal network, but nothing going over the internet.
Thank you for your clarification. So, if I understand correctly, I will apply the QoS on the DMZ Interface (facing the WebEx), and will only be applied on internal subnets. If I want to apply it, should I ask the ISP to apply the QoS on my traffic?
