How to block Reassembled TCP data?

Question

Nginx

Good day!
There is a dump, when opening it through Wireshark, there is a Reassembled TCP Data field
. Is it possible to somehow block this header using iptables, or using nginx?

Answer 1

In nginx, it’s definitely not in the firewall, look at extended xtables, if the date is the same, you can definitely

Answer 2

What makes you think it's some kind of headline?
It's just WireShark telling that this TCP packet containing 437 bytes of data was split into two frames, #87, 62 bytes long, and #110, 375 bytes long. Wireshark, when analyzing, collected these frames back into one packet, which it shows.
