technically i think it is a real error to use a /24 alias, but i
am not 100% sure about the amt of problems it causes.

if you do care about this, you may want to restructure the data structure
used to store/match interface addresses. At the moment it is a linear list,
so the matching of incoming packets is probably Very Time Comsuming!
