I just wonder what's up with people that hit reply and send without
writing anything (or even adding to cc).

Hi netfilter family,
I'm a newbie to netfilter.
I have just developt a crypto module using netfilter hook.
In this module :
SENDER : IP payload will be encrypted at POST ROUTING hook
RECEIVE : IP payload wil be decrypted at PRE ROUTING hook.
The module work fine with ICMP & UDP but it NOT work fine with TCP: 2
machine still receive packet at hook but application not communicate
together.
I don't know whether any mystery in netfilter or linux network kernel at here?
Thanks :)

And what makes you think we would know what happens in your hidden code?
