Dear Michael,
Thank you for reaching the Small Business Support Community.
I would first suggest you to upgrade to the latest firmware release version 1.0.4.10;
http://software.cisco.com/download/release.html?mdfid=282981372&softwareid=282487380&release=1.0.4.10
If nmap still shows the port opened, I then suggest you to disable the remote management to determine if this is the root of the problem, then contact the Small Business Support Center to have a TAC engineer figure this out;

Please do not hesitate to reach me back if there is anything I may assist you with.
Kind regards,
