Of course static IPs are the best and easiest solution.

Actually, most "residential" broadband internet service contracts
specify that you will not run servers, of any sort.

I know my ISP actually scans port 80 of all residential customers,
looking for web servers, and will harass the customer if they find one.
They also block port 25 making it impossible to run a standard mail server.

Of course you could run on non-standard ports, but if you look into it
you will often find that the cost of a "business" account, which permits
servers and does not block any ports, is only minimally more than
residential service, and often includes a static IP, or makes one
available for pennies a day.
