Question. Iniside firewall as in "on separate machine inside firewall",
or as in "on the same machine as firewall"?
In former case, it might as well be that the packet you are seeing had
spoofed IP address, and that it originated inside your network. Is eth0
on your LAN or outside. Another case could be that you have ommision in
firewall rules (so that "what is logged is not always dropped").
In later case, what you are seeing is what you were supposed to see (if
I'm correct on how snort works, by sniffig network traffic directly from
the network interface).
