Traffic shaping with VPNs is a tricky topic because VPN traffic is considered separate from, but also a part of, the WAN traffic through which it also flows. If WAN is 10 Mbit/s, then the VPN can also use 10Mbit/s, but there is not actually 20Mbit/s of bandwidth to consider, only 10Mbit/s.
So I maintain and operate my own VPN server to run traffic through. I find that when using a VPN pages will timeout and uploads using BTSync are slow and intermittent. Last night uploads were running at 40KB/s via the VPN. I disconnected from the VPN server and continued syncing using a direct connection at 00:01 and uploads were running at Nov 18, 2018 · Traffic shaping uses concepts of traffic classification, policy rules, queue disciplines and quality of service (QoS). Why implement Traffic Shaping? Network bandwidth is an expensive resource that is being shared among many parties of an organization, and some applications require guaranteed bandwidth and priority. VoIP Traffic Shaping in a VPN Tunnel 06-05-2008 12:15 PM I am using an SSG5 with a route-based VPN tunnel to an SSG140 and I am passing VoIP and data traffic through the tunnel. Since VPN traffic comes on the external NIC, there is no way to shape it on the internal NIC. If I shape traffic on the external NIC, I lose the ability to shape traffic per (LAN) IP. To avoid starving VPN users, I have lowered the total bandwidth available to LAN users to make some headroom for VPN users (but I am leaving unused bandwidth) Use A VPN To Bypass Traffic Shaping. The only real way to avoid these practices, at least at the ISP level, is to use a VPN. VPN, virtual private network, is an Internet Protocol first created for use by large corporations and governments and now available commercially for home use.

A Virtual Private Network (VPN) is a tunnel that carries private network traffic from one endpoint to another over a public network such as the internet. VPN allows users to transfer data as if their devices were directly connected to a private network. What is Traffic Shaping (Packet Shaping)?
Sep 20, 2018 · This article demonstrates how to set up Quality of Service (QoS) to reserve an amount of bandwidth for the VPN traffic all the time, in order to ensure the VPN performance. 1. Go to Bandwidth Management >> Quality of Service, click Edit on a class rule. 2. Name this class, and click Add to add a new rule. 3. For LAN-to-LAN VPN, edit the rule as
"Cisco Meraki Client VPN only establishes full-tunnel connections, which will direct all client traffic through the VPN to the configured MX. As such, any content filtering, firewall or traffic shaping rules will apply to the VPN client's outbound traffic. Note: Traffic shaping is only supported on ASA Versions 5505, 5510, 5520, 5540, and 5550. Multicore models (such as the 5500-X) do not support shaping. With traffic shaping, traffic that exceeds a certain limit is queued (buffered) and sent during the next timeslice. This recipe also explains how to configure traffic shaping to set a maximum bandwidth limit for uploads and/or downloads to 200 kb/s. 1. Enabling Traffic Shaping. Go to System > Feature Select and under Additional Features enable Traffic Shaping. Two new traffic shaping menus, Traffic Shapers and Traffic Shaping Policy, will appear under Policy Traffic shaping provides a means to control the volume of traffic being sent into a network in a specified period (bandwidth throttling), or the maximum rate at which the traffic is sent (rate limiting), or more complex criteria such as generic cell rate algorithm. This control can be accomplished in many ways and for many reasons; however Traffic shaping is an integral component of the proposed two-tiered internet, in which certain customers or services receive traffic priority for a premium charge. Importance of traffic shaping. Traffic shaping is important when network uplinks become overwhelmed with data being sent out of an interface. Without traffic shaping, any excess
