Hi
After i wrote the e-mail to the list i figured out how to get the
ethernet destination address of the packet. I'm not sure but this might
help me because i need to figure out if the packet is moving towards me
or away from me on the interface i've chosen. So i can compare this with
the ethernet address of my chosen interface and figure out where it's
going.
Stop me if i'm wrong. :)

Hi
I'm sniffing packets with pcap but i need information about where the
packet is going.
This is a decision made by the routing table, so there's no good way to
'guess' where it will go before the packet reaches the outgoing queue of
the IP layer.
I'm thinking i need to open two pcap sessions with two different
filters because the application i'm writing has a need for
distinguishing between packets going to a specified ip-address and
those going from it.
Well, the destination IP address should be easy to grab. Even if you do
get hold of that though, you may have to listen to multiple pcap
connections to find out where the routing decisions send the packet on
its way out.
