So in your example you can manage QoS within the VPN but have no control whatsoever over the VPN tunnel as a hole, it would be the same result as if you just passed straigth TCP over your connection with QoS, however you will waste more resourses for the VPN and probably introduce a bit of latency, small but latency none-the-less.

Hi All<br><br>Could a VPN be used to help with SIP Tunneling and QoS issues.<br><br>State 1:<br>Two IP Networks Connected via the Public Internet transmitting VoIP Traffic<br>Say a VoIP User and VoIP Termination Provider.
<br>Each side can put QoS onto their part, but if QoS does NOT exist between<br>them<br>then call quality will be bad anyhow.<br><br>State 2:<br>Same as above except a VPN tunnel is setup between each side.<br>Thus making them appear on the same network and possibly same subnet.
<br><br>(1) Would this now traceroute a one hop ?<br>(2) Would this have a lower or higher ping time, thus latency ?<br>(3) With the additional Encryption etc.. if using a 1 Mbps Internet<br>connection<br> What would the "actual" amount available now be 700kbps, in other words
<br> How much overhead is there with a VPN tunnel that would reduce the<br>available bandwidth ?<br><br><br>Thanks to all<br><br>_______________________________________________<br>--Bandwidth and Colocation provided by
