Avoid the reload of a specific package after PPPoE WAN address is changed

[arielgrin]

Dear all: I'm using pfSense 1.2.3 with a PPPoE WAN connection.
My ISP resets my connection every 24 hours, probably to stop me from having the same IP for a long period of time.
Every time the WAN address gets changed, pfSense restarts all its packages, as it is supposed to do, but I would like to prevent one of the packages to be restarted, which is the NUT package. Is there a "clean" way to do this? I would like the script to restart every package except NUT, and since I don't know which script I should be modifying to acomplish this, I would really apreciate your help.

Thanks!
