Actually, this specific connection is an MPLS circuit, so traffic prioritization through the ASA should provide some legitimate QoS. Regardless, though, I would expect the latency to have some consistency if QoS were configured properly -- the jump from 30 ms to 300 ms specifically when non-tunneled traffic is sent across the same circuit seems to indicate that I have something configured wrong.

By default, all VPN traffic is forced to route to the ASA first. By configuring split tunneling we can allow our users to use their Internet connection to browse the web, instead of their traffic hitting the ASA and then going to the Internet. This filters only the traffic that needs to travel to the corporate network.

So there you have a QoS configuration using policing, for any VPN traffic traversing the ASA. Now lets move on to QoS for VPN’s terminating on the ASA. So here we extend our topology to include a branch office and an external partner. Both sites will have a VPN terminating on the ASA, using the VPN Tunnel Groups 192.1.2.2 and 192.1.2.3 Once the traffic enters this uncontrolled space (think the Internet) packet behavior is unpredictable. There is nothing that can be done to prevent packet drops once the traffic enters the l2l VPN tunnel. End-to-End QoS is required to change the likelyhood of a packet being dropped as it transits the network. ISP's treat all traffic as best effort, even VPN traffic. To get true QOS capabilities you would have to use a private connection like MPLS or a point to point circuit. VPN's and VOIP are hit and miss. I have seen some work well, and others not so much. Mar 06, 2012 · There are several challenges related to QoS in the typical Internet connected environments that I come in contact with. These challenges are not really a result of the VPN configuration, but it is often mission critical traffic that we are trying to prioritize through the VPN. This traffic is competing with other Internet destined traffic. 4. Now apply that policy-map with a service policy. (Note: Generally you apply the policy to the interface closest to where the traffic is coming from, as this is an internal host, I’m applying it to the inside interface. If you were throttling traffic from outside it would be better to apply the service-policy to the outside interface).
