The devil is in the details. Congrats!
I haven't spotted it before either.

> Hi Marc,
> Inspired after your training, I did some testing with the

> After sending a (unsolicited) neighbor advertisement for the current
> default router with the router set to false, both Ubuntu 12.04 and
> Windows 7 remove the router from the default router list.

> try and get into your code, but it will probably take a while. Also,
> I'll have some other operating systems to test it on next week.
> Thanks again for the training, I had a blast!
