The 23. and 24. probes are almost certainly decoys. This may be an 'nmap'
scan trying to determine your IP sequence number algorithm - using bogus
packets to increment the initial sequence number. You may wish to verify
whether your software is configured to report on probes to other ports
as well - it could be you're only reporting on "interesting" ports (like
snmp, netbus, yadda yadda yadda) and you missed the other connections.

Of course, I may be totally full of it too - it *is* 5:30PM on Friday and time
for the weekend. ;)
