QOS and internet traffic

L4 Transporter

Can PANOS controll / rate limit  internet downloads ?

 

On my squid boxes I can ratelimit and it does this by delaying acks.

 

Can the PA QOS do this work as well ?

Thought I would come back to this.

 

So it can only apply QOS to the egress interface.

 

so if you have a PA with eth1 -> internet and eth2 -> proxy server.

 

you apply QOS for internet download traffic to eth2

 

you can't apply QOS on eth1 for inbound.

 

Not exactly what I wanted but atleast now I know

 

The advantage of applying QoS on the egress interface is that at that time paloalto already knows a lot about the traffic that it is processing (specially the app) so it gives you the possibility for very granular bandwidth limitations per app/app group/app filter group...

The problem is QOS doesn't just work on sub interfaces it works on the whole interface.

 

I have a 80G LACP ae and QOS only works up to 40G from memory, so to turn on QOS I have seperarte out interface. I prefer a single trunk with sub int on it.

 

it would be nice if it slowed ACK's back to the web site for web site downloads.. like squid does
