By using the debug command how can I tell if traffic was passed or rejected from a specific IP or range.  For instance here is the output I recieved in my test.  I know that it was blocked but what in the output will confirm that for me?

--------- PACKET ---------

-- IP --
Source ==>     Dest

        ver = 0x4       hlen = 0x5      tos = 0x0       tlen = 0x30
        id = 0x6321     flags = 0x40    frag off=0x0
        ttl = 0x7e      proto=0x6       chksum = 0xb494

        -- TCP --
                source port = 0x7b0     dest port = 0x17syn

                seq = 0x166cf6da
                ack = 0x0
                hlen = 0x7              window = 0xffff
                checksum = 0x88ff       urg = 0x0
tcp options:
                        0x2     0x4     0x5     0xb4    0x1     0x1     0x4
0x2

It doesn't.  This is only a packet capture.  You could compare this to what you see blocked in the fw logs ?
