MSS clamping does not work

[kxa]

Hi

I've a pfSense 2.4.5_1 running several interfaces all vlan based on one physical interface (em0).

I've set the MSS to 1452 on each interface (ex. em0_vlan30) but if i check with "Paket Capture" the SYN pakets were marked with MSS=1460 (the default one).

What are we doing wrong?

Thank you in advance
