I searched on TCP/IP port listing
From the quick reading I did, I couldn't tell you if it's good or not.

Hi Troy,
You know, I did try google, but for some reason the phrase 'Port 1' doesn't
return much :\
(http://www.google.co.uk/search?sourceid=navclient&ie=UTF-8&oe=UTF-8&q=I
SA+%22destination+port%22+%22port+1%22)
Should I be expecting this from my a DC on my internal network? I've done a
scan and have found nothing. Then I allowed the traffic through, and now it
has stopped. Very bizarre. Would be great to know exactly what it was.
Thanks for putting me on track with tcpmux though :)
Cheers,
Jason
