Question on QOS

[JRussell]

QOS is something I am looking to start using for a few things but I just had a couple of questions about it.

So firstly, I can set a QOS rule and assign a class. I know I can create profiles on the class, but lets just say I use the default classes that are setup. If I create a rule saying that a particular range of IP's going through my internet connection have a class 8 for skype this should then limit the bandwidth they can use for this application correct?

Also, do I have to setup a rule for all other traffic or if not then what class does all other non specified traffic go on?

And lastly. The QOS profile needs to be applied to the interface the traffic will be coming in on or going out on?

Thanks in advance

So if I do it on my Wan interface then I will need to set a QoS profile for each tunnel on that interface correct? At least that is what it seems to suggest when I tried it

if you are limiting traffic on the tunnel interface then yes, other wise for normal WAN traffic going out configure the QoS on the untrust/WAN interface of the PA.

Thanks for the explantion. I have another related question.

I have the following setup and want to limit traffic from VLAn 3779 to the Internet VLAN 3662 and the other way round. How must I do this? The problem is that I can configure QOS only on interface1/8 and not on subinterfaces. Thanks for your help.

Thanks for the fast answer. Can you tell me what this option is useful for?
