VPN MSS Clamping Option?

[mossywell]

Hi there, OK, I'm being stupid or blind or both! I can see other posts about this option, but I just can't seem to find it in the GUI. Can someone please tell me where in the GUI it is?
Many thanks

The legacy setting was removed in favour of a flexible normalisation rule framework, see Firewall: Settings: Normalisation, I believe you're looking for "Disable interface scrub".
