Dear all: in my service, there are four net card. eth0, eth1, eth2, eth3. I want to forward the data in from eth0 to eth1, eth2, eth3 with different application protocol. Does some body send me some ideas on it? 1) where i should set the hook: pre-routing or forward? 2) how to make the route select the target port which i hope? 3) where i can get some simple source code to learn?
