if i do an snort -vd i can see payload on all interfaces eth0, eth1 and ppp0
sorry. ppp0 & eth0 are on the same interface.You could try a Tap between ppp0 and eth0. That might solve your problem without too much work. Google "network taps" and you should get a good variety of info and vendors to check out. One note, if you tap you will need to build a snort box with 2 sniffer interfaces. One for receive traffic and one for send traffic as the tap will spilt them up on two different lines.
