Hi Dan!
You could get service from http://www.dyndns.org/services/dyndns/ and then you would add something like: svoboda.dyndns.org[TAB]OK Your home dynamic IP would always resolve to that using one of the update clients they recommend.
I guess this will work, got some of that dyndns stuff already @home and @work. But there are some sites on the server with several users sending eMails - so everyone had to do this procedure. Still sounds a bit un-handy imho...
Regards, Frank
