WebRTC IP Handling Policy for URL Patterns

Computer and userIntune-readyWebRtcIPHandlingUrl

Supported on Microsoft Edge version 135, Windows 7 or later

155.0.4283.62

What it does

Controls which IP addresses and network interfaces WebRTC can use when establishing connections for specific URL patterns. How It Works: Accepts a list of URL patterns, each paired with a handling type. WebRTC evaluates patterns sequentially; the first match determines the handling type. If no match is found, WebRTC defaults to the WebRtcLocalhostIpHandling WebRtcLocalhostIpHandling. policy. This policy applies only to origins—URL path components are ignored. Wildcards (*) are supported in URL patterns. Supported Handling Values: default – Uses all available network interfaces. default_public_and_private_interfaces – WebRTC uses all public and private interfaces. default_public_interface_only – WebRTC uses only public interfaces. disable_non_proxied_udp – WebRTC uses UDP SOCKS proxying or falls back to TCP proxying. More Information: Valid input patterns: https://go.microsoft.com/fwlink/?linkid=2095322 Handling types: https://tools.ietf.org/html/rfc8828.html#section-5.2 Example value: [ { "url": "https://www.example.com", "handling": "default_public_and_private_interfaces" }, { "url": "https://[*.]example.edu", "handling": "default_public_interface_only" }, { "url": "*", "handling": "disable_non_proxied_udp" } ]

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: WebRtcIPHandlingUrl
