Smoothwall - double filtering results

[synaesthesia]

Odd one, in testing with our new Smoothwall. Most seems OK, however a couple of oddities:

 

A couple of clients, Chrome filters differently to Edge. Same proxy settings etc (well, it's transparent ). 888.com works for Chrome but is correctly blocked by Edge.

 

And this... I just don't know. Twitter, reddit etc correctly blocked but Facebook is doing this.

 

 

(And yes, it works for the user).

Any clues?

Possible built in DNS?

Oooh, cheers didn't know about that one. Disabled already on managed browsers though.

Filtering different in 2 browsers usually means one is using QUIC or HTTP3 and getting past the filter that way

Legendary - QUIC it was

That's a quic fix!

 

I'll see myself out...
