Dear all,

I'm simulating an network environment that some TCP segments are missing. So I want to use iptables to drop these segments. How to write a rule to drop a segment with a specific sequence number from a host? Thanks in advance.

Best regards,
Yuwen Dai

I suppose you can start playing around with --u32 ?
