All firewalls (that I know of) allow you to Open Ports, or allow traffic to
flow through a given port. A non-configurable firewall would pretty much,
in my opinion, be one out of your control completely... Lke your corporate
one.
Most of the DSL/Cable routers these days also allow for port forwarding and
the likes, too many problems with even common issues like games and remote
desktop and the likes, so they wouldn't sell any products if they weren't
configurable like the software NAT products.
The DHCP issue is worked around boy other free services like DynDNS.org -
which can assign a name to your IP and when your IP changes, the name
follows it. Not all Cable/DSL routers will do this, but the better ones
will allow for entry of this information and even have suggestions (like
DynDNS.org) of whom to use.
With Port Forwarding or Configuring a Firewall with open ports, NAT boxes
(like DSL/Cable routers or free software software) and services like
DynDNS.org - there is very little reason to pay for a service that is built
into your Windows XP system or that you can get a substitute for (like
UltraVNC) as a free thing!
