I have a linux (Ubuntu Server) machine configured as a PPP router (iptables masquerade), when capturing on the ppp0 interface I would like to be able to see the source or destination as the internal machine to which the packet is being routed to/from rather than the router's ppp0 IP address.

This could be done by capturing eth0 but I would like to only see packets going through the ppp0 interface and the actual router box's traffic over ppp0. I'd prefer to do this without filters.

Thanks in advance!
