The point I was trying to make is that the documentation isn't 100%
correct in regards to this ;-) To verify this you could try and search
(i.e. Google) for any other reference to this issue.

OK! Sorry, Brian!
So forget that (gARP over PPP connection), OK? I don't understand how
this vulnerability (gARP) can be exploited or can't be after disabled
the feature. If the router (after disabled gARP) still received (not
send out) gARP, this device still don't continue vulnerable to fake
rARPs from a attacker?

Thanks!
