Read this to understand the setup of my networking:
You see that I have to force the subnet mask to something other than
the one that the adsl router uses, in order to get routing working at
all. Strangely enough, this problem doesn't exist at all on linux. It's
a FreeBSD peculiarity. Anyway, I wouldn't consider using linux for my
