whitenoise Posted January 24, 2016 Share Posted January 24, 2016 Hey guys, is it possible to put a Raspberry Pi (having two ethernet ports) in the middle of a network connection monitoring all the traffic but without having an IP address assigned to the Pi? I want it to be there 100% invisible and passive, basicaly I only want to use the forward option in the ip tables and put a loop in between which sends all the packets via nfqueue through a python script which then is able to filter the packets at an optional level up to some kind of dpi. I'm not sure if I can prohibit it getting an IP assigned because I don't want it to be accessible. I guess I need some nice configuration for the /etc/network/interfaces file, the routing can be done with iptables at startup, which should not be a problem. All the other stuff with python and nfqueue also isn't the problem for me. Quote Link to comment Share on other sites More sharing options...
