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?
