hi , i am trying to develop firewall using libpcap in user space. whenever packet comes to ethernet layer before passing the packet to kernel protocol stack libpcap takes a COPY of the packet. so is it possible to develop a userspace firewall using libpcap where i require to intercept the packet and process it before giving it to kernel protocol stack. looking for ur help.
