True, I can and will. But I like to configure all layers and multiple
times, then set "traps" (log exceptions/notify) at all levels, except
the outermost.
If _any_ of those fire, I know I have a problem and someone
sidestepped at least the outermost "firewall".

Also, it is real fun to make something actually work (i.e. connect),
you need to understand exactly what goes on, spend countless hours
drinking coffee while poking at packet traces, etc.
And even MORE fun when something DOES break and you need to fix it
ASAP in the night.

DISCLAIMER: I don't expect any one to agree with what I think or do.
And I do occasionally take advice and "improve" things. And I always
quote my $VARs.
