Found my answer:
I went into the router via telnet and looked thru the nvram settings using:
I then found the errant entries. They were listed in the nvram as forward_port# where # was the entry (there were 9 of them). I didn't want to zero the values out, I wanted the values gone altogether. I did this by typing the following:
Code:
nvram unset forward_port0
nvram unset forward_port1
...
...
nvram unset forward_port8
I then re checked the nvram contents and the forward_port entries were gone.
I then wrote the nvram back from ram to make the changes permanent using:
I then rebooted and the entries are gone (and upnp is behaving itself both entering and releasing the entries as intended).
