how to find dyndns server
 

sorry i'm completely new and not sure what the dyndns server referred to in the setup guide is. Can anyone shed some light?

dyndns is a site you go to, to setup a dns record for other people to resolve to your server (IE www.yourserver.dyndns.com, instead of your outside IP address). they have an app on thier website that will automatically update your ip address to your record. it just makes it easier to keep a dynamic ip address updated, so you don't have to do it manually. its free unless you want your own custom dns name.

thank you I really appreciate your help

That's actually pretty sick
