I did some work on one of these once and I took the attitude that
segmentation "games" and all the funny things that can happen (but
99% of the time don't in normal behaviour) were something that could
be just dropped on the floor.  Easier to get the user to hit "reload"
than try handle all the stupid cases that are only ever likely to
occur when someone is trying to bypass/confuse filters, etc.  Why
could w do that?  Well, when the outgoing proxy is on a locally
connected network and the proxying that is happening is outbound
connections only, everything should be smooth...

So I imagine it would be "Muaha" back :)
