Confused about QoS on Palo, need some assistance.

My understanding is that QoS only really applies to egress.

The issue I faced this week was with Apple updates killing the ingress and impacting sip trunks.

Egress didn't appear to be an issue.

Now with that said, would applying QoS within our Palos help in any way when it comes to the sip trunks if the issue is with ingress being saturated?

What could you possibly do in this case?

Hi @latechguy ,

Yes! This can be done. See the 2nd paragraph in this article. https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClS0CAK

You can limit your untrust ingress by applying policy to your trust egress, especially with TCP-based traffic, which will decrease the sliding window based upon packet loss. The article also has good stuff for your SIP trunks.

Thanks,

Tom
