Yep, precisely.  You're running a business/professional type of
configuration on a consumer-grade circuit.  Your ISP has to assume
that you're Joe or Jane Luddite with an unpatched Windows PC when you
buy this configuration, but your requirements are outside of the
standard product definition (and best current practices) for consumer
b/w.

Buy an appropriate connectivity product for your home connectivity and
the problems go away.  Put your servers in a colo (a la
http://www.vix.com/personalcolo/ ) and the problems go away.  It costs
more to maintain a zone file that is not created by a perl script (ie,
your generic rDNS).  You can expect to pay for this.  Presumably as a
Unix sysadmin with 15 years of experience, this is a cost you can
afford/justify.
