setting the WAN IP to a xxx.xxx.xxx.xxx works fine as long as your ISP doesn't rotate your addy. I am on cable which is "dynamic", but I seem to always get the same IP I had before even if I reset my modem or leave it off for a few weeks and turn it back on when I return from vacations.
Anyway, an alternate method to using the static IP scheme is using a dynamic host such as
www.dyndns.org. you can then replace the WAN IP used in your xml and ini files with what ever your dyndns address is. example
http://eq.homedns.org instead of 97.82.210.231
