      Hello

      I get in the logs this line

      discard oversize frame (ether type 8864 flags 3 len 1522 > max 1514)

      What does it mean, and how I can set it or change values ?

      thanks.

        Some frames that are too large are hitting one of your interfaces. This usually shouldn't happen. Search the forum, this has been discussed some time ago already somewhere. Basically it's not a pfsense problem but a problem with the traffic on the wire. pfSense is just reporting it.

            1514 is the max frame size of Ethernet (excluding jumbo frames, which aren't used on the Internet), which is likely what your WAN is. You shouldn't ever see > 1514 on the Internet.

            I'd just ignore it.
