making packets

Post by Felix » Wed Dec 01, 2010 7:07 pm

I am using the libnet library to generate custom packets over a vpn network, but because i have libnet working at the lower levels of the OSI model the packets are bypassing whatever method openvpn uses to force all traffic through to the vpn server.

I tried adding 'push "redirect-gateway def1" ' to the server.conf file but it didnt work.

I would like to try to modify openvpn so that I can give it my custom made packets to send over the vpn, and I was wondering if anyone could tell me where in the source code openvpn either constructs or captures the original packet before it encapsulates it?

Thanks!

are your packets IP packets? your routing table is what decides to send things over openvpn or not
