Smoothwall content modification

[TechMonkey]

Is anyone using Smoothwall content modification on YouTube successfully? I thought we had it all set but we are suddenly getting reports of adverts and comments appearing. Just wondering if it is something odd with us, if Smoothwall changed something or if YouTube have countered it?

No reports of it not working as far as I can tell - 2 things to make sure of is

 

1: https inspection needs to be enabled for Youtube - I assume this is the case otherwise those mods would have never worked.

 

2: Block QUIC outgoing. If the Smoothwall is the firewall as well as the web filter, make sure to put a firewall policy in place to block outgoing requests to UDP ports 80 and 443 - those are used by the QUIC protocol, which Youtube will use if it can, bypassing filtering.

 

There is a content mod to remove the QUIC header but if a browser is already in QUIC mode, then the content mod wont help.
