I agree Luis.. ;)

Really tho.. I haven't been on her in a week and was just about to post the 

Here's the updated version of my SOHO firewall presentation:

But also, as others have already echo'd, you probably shouldn't run many (if 
any) "internal apps" at all on a "Real firewall" (for obvious security 
reasons).  Instead, set up your app servers internally.. which follows into 
Part-II of the presentation from that month, setting up an internal

Great presentation that one (but better in person by Robert himself).

Running systems like these 24x7 does bump up the old electric bill a bit.  I 
would guess $30-40/month (in my guesstimate).  However that's also an 
advantage of the underclocked "fan-less" high availability (no moving parts) 
strategy that I outline in my piece (the first link).  I supposed the same 
could be done on the web/MTA server too.. but doing so you would really want 
to strip out all the un-needed stuff on the server like the X11/GUI, etc.. 
and probably admin it headless via a web-admin app such as webmin

I dunnknow.. Hosting at home can be done pretty well.  Especially if you want 
to set up and run on services like dyndns, etc...  Keeping in mind... you're 
responsible for the whole shootin' match if something goes wrong (err.. 
when).. and some ISPs might decide to just suddenly decide to shut you down 
if they see traffic they don't care for (or the up and change their policies, 
etc).   But in the immortal words of Elwood Blues:
