This morning I'm seeing a large number of SYN probes from
210.97.123.3. They all seem to be directed at port 109 (pop2).
They also run up our IP range so I think they're searching our
subnet for something.....

This scan might be trying to get passed your firewall. I don't
think having the "syn" and "fin" bit set is normal. Also, the
destination port of "0" is a bit wierd.
