We run our site-to-site VPNs in a tunnel-all configuration to enforce content filters, IPS, app detection, etc. Recently my company has selected a Internet-based learning management system for staff training. At times it can be a bit of a bandwidth hog. With all of the other traffic I have going through my WAN I would like to guarantee that it has a certain amount of bandwidth. Now with physical interfaces this is pretty easy. I have a LAN (named default-profile-lan) and WAN (named default-profile-wan) QoS profile and set aside 10ms/s on each for Class 2. Since it is egress based I wanted to make sure that any traffic uploaded or downloaded is covered. The issue I am struggling on relates to how I guarantee it though a site-to-site VPN tunnel. Since the WAN interface is my ingress & egress interface for all VPN terminated traffic, would Class 2 under default-profile-wan apply for both directions or would I need to do something with guarenteed traffic on a tunnel-by-tunnel basis. My QoS rule is structured as
|Name||Tags||Src. Zone||Src. Address||Src. User||Dst. Zone||Dst. Address||Application||Service||Class||Schedule|
I would think that this would apply for any traffic coming from my vpn-tunnel zone or inside zone and use the default-profile-wan policy, but I could be wrong. Can anyone shed some light on it?
