pfSense

From my comments on that thread (slightly edited to make sense here):

It's using a variable set inside the per-interface foreach outside of the foreach, so the results may be unpredictable depending on whether it's set on the last interface or not. It's trying to take a per-interface setting and trying to apply it globally.

The code right above that for disableauthoritative and alwaysbroadcast has the same problem.

There is an open request to make a dedicated settings tab at #5080 which may be the end result here, though the items mentioned on that issue are not all relevant or likely to happen in this release.
