## Frequently asked questions ## Frequently asked questions
**Does Delivery Optimization work with WSUS?**: Yes. Devices will obtain the update payloads from the WSUS server, but must also have an internet connection as they communicate with the Delivery Optimization cloud service for coordination. #### Does Delivery Optimization work with WSUS?
Yes. Devices will obtain the update payloads from the WSUS server, but must also have an internet connection as they communicate with the Delivery Optimization cloud service for coordination.
**Which ports does Delivery Optimization use?**: Delivery Optimization listens on port 7680 for requests from other peers by using TCP/IP. The service will register and open this port on the device, but you might need to set this port to accept inbound traffic through your firewall yourself. If you don't allow inbound traffic over port 7680, you can't use the peer-to-peer functionality of Delivery Optimization. However, devices can still successfully download by using HTTP or HTTPS traffic over port 80 (such as for default Windows Update data). #### Which ports does Delivery Optimization use?

However, devices can still successfully download by using HTTP or HTTPS traffic over port 80 (such as for default Windows Update data).
If you set up Delivery Optimization to create peer groups that include devices across NATs (or any form of internal subnet that uses gateways or firewalls between subnets), it will use Teredo. For this to work, you must allow inbound TCP/IP traffic over port 3544. Look for a "NAT traversal" setting in your firewall to set this up.

**What are the requirements if I use a proxy?**: For Delivery Optimization to successfully use the proxy, you should set up the proxy by using Windows proxy settings or Internet Explorer proxy settings. For details see [Using a proxy with Delivery Optimization](./delivery-optimization-proxy.md). Most content downloaded with Delivery Optimization uses byte range requests. Make sure your proxy allows byte range requests.

**Does Delivery Optimization use multicast?**: No. It relies on the cloud service for peer discovery, resulting in a list of peers and their IP addresses. Client devices then connect to their peers to obtain download files over TCP/IP. #### Does Delivery Optimization use multicast?

**How does Delivery Optimization deal with congestion on the router from peer-to-peer activity on the LAN?**: Starting in Windows 10, version 1903, Delivery Optimization uses LEDBAT to relieve such congestion.

**How does Delivery Optimization handle VPNs?** #### 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." 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 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.

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 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 using a VPN, it can still use peer-to-peer with the default of LAN.

#### How does Delivery Optimization handle networks where a public IP address is used in place of a private IP address?
Starting with Windows 10, version 1903 or later, Delivery Optimization no longer restricts connections between LAN peers to those using private IP adddresses. If you use public IP addresses instead of private IP addresses, you can use Delivery Optimization in LAN mode.
> [!NOTE]
> If you use public IP addresses instead of private in LAN mode, the bytes downloaded from or uploaded to LAN peers with public IP addresses might be reported as coming from Internet peers.
