This version of Skype also uses the Operating System proxy settings and has no individual settings. Microsoft does not provide a list of IPs or hosts that MWG can bypass. The browser plug-in can't be configured to use a different proxy port. It is not possible to handle such connections in MWG and intercept them with the SSL scanner. The browser plug-in uses the default client settings. Add the following criteria to the SSL Scanner rule set: Exclude this proxy port from the SSL Scanner.For Transparent common name handling, set as False.For Serve transparent SSL connection, set as True.In the HTTP port definition list, configure the new HTTP Proxy with the following settings:.Select Configuration, Appliances, Proxies (HTTP(S), FTP, SOCKS, ICAP.To inspect the Skype application traffic, McAfee recommends that you configure another HTTP proxy port in the McAfee Web Gateway: If you enable bypass in the Skype for Business/Lync rule set, it covers Team voice traffic as well. NOTE:To exclude Microsoft Teams, configure a normal policy allow list, to exclude traffic from scanning.Īlso, the subscription list McAfee offers in the Office 365 rule set, covers Microsoft Teams exactly like Skype for Business or Lync.
