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.
