**How does Delivery Optimization handle VPNs?**
Delivery Optimization attempts to identify VPNs by checking the network adapter type and details and will treat the connection as a VPN if the adapter description contains certain keywords, such as "VPN" or "secure."
If the connection is identified as a VPN, Delivery Optimization will not use any peer-to-peer activity. However, you can allow peer-to-peer activity over a VPN by using the [Enable Peer Caching while the device connects via VPN](waas-delivery-optimization-reference.md#enable-peer-caching-while-the-device-connects-via-vpn) policy.
If the connection is identified as a VPN, Delivery Optimization will suspend uploads to other peers. However, you can allow uploads over a VPN by using the [Enable Peer Caching while the device connects via VPN](waas-delivery-optimization-reference.md#enable-peer-caching-while-the-device-connects-via-vpn) policy.
If you have defined a boundary group in Configuration Manager and have for VPN IP ranges, you can set the DownloadMode policy to 0 for that boundary group to ensure that there will be no peer-to-peer activity over the VPN.
If you have defined a boundary group in Configuration Manager for VPN IP ranges, you can set the DownloadMode policy to 0 for that boundary group to ensure that there will be no peer-to-peer activity over the VPN. When the device is not connected via VPN, it can still leverage peer-to-peer with the default of LAN.
With split tunnelling, it's best to exclude the boundary group for the VPN devices to exclude it from using peer-to-peer. (In this case, those devices won't get the policy and will default to using LAN.) If you're using split tunnelling, you should allow direct access for these endpoints:
