-For downloads from HTTP sources, Delivery Optimization can use the automatic proxy discovery capability of WinHttp to handle communication with the proxy server. It’s important to know, Delivery Optimization uses byte range requests, so you’ll want to make sure your proxy allows this capability.

 If your environment requires a more granular approach, you can use the restrict peer discovery setting alongside the download mode to achieve more control. For example, if you have several different subnets behind the same NAT but want to limit your peer groups to a single subnet, choose [DODownloadMode](waas-delivery-optimization-reference.md#download-mode) (1) and [DORestrictPeerSelection](waas-delivery-optimization-reference.md#select-a-method-to-restrict-peer-selection) (Subnet).

 #### Peering with VPN
 
-By default, if Delivery Optimization detects a VPN, peering is not used. To change this behavior, use the [DOAllowVPNPeerCaching](waas-delivery-optimization-reference.md#enable-peer-caching-while-the-device-connects-via-vpn) policy. The Delivery Optimization client looks in the network adapter’s ‘Description’ and ‘FriendlyName’ strings to determine VPN usage. To allow greater flexibility for VPN identification, use the [DOVpnKeywords](waas-delivery-optimization-reference.md#vpn-keywords) to add descriptors for a particular VPN you use in your organization.

-* Help optimize peer connection over HTTP connections using the [DOMinBackgroundQoS](waas-delivery-optimization-reference.md#minimum-background-qos) policy. A good value for the [DOMinBackgroundQoS](waas-delivery-optimization-reference.md#minimum-background-qos) policy is something lower than the average download speed seen in your network.

To improve efficiencies from peers or a dedicated cache server, a good starting point is 60 seconds for background settings and 30 seconds for foreground settings.
