Smoothwall has added a category called "Games Consoles". This category covers access to game services used by Xbox, PlayStation and Nintendo devices and others.
Issues with games consoles
Games consoles can't authenticate to a proxy automatically. Neither NTLM nor Kerberos methods will work for those. Additionally, redirecting to a login page isn't reliable because users won't be browsing on their consoles. To prevent a games console spamming requests to a login page on a Smoothwall, you can add this category to the list of included categories in "Web proxy - Authentication - Exceptions" to avoid this issue.
We also recommend that you add the Games consoles category to a "Do not inspect" policy in "Guardian - HTTPS Inspection - Manage policies".
