Subjectmagic routes: final fix
Date
Hello!

I hope this patch will resolve the problems with magic
routes, that were present since 1.3.99.
Note that my previous fix (Subj: "route+arp FAQ..."),
integrated into 1.99.7 was not complete.

I'd like ask for people who suffered from magic routes
apply this fix to 1.99.7 (or 5,6) and test it.


Alexey Kuznetsov.
