Just because it is behind a NAT doesn&#x27;t mean you can&#x27;t run a server.  You just need to set the router to forward traffic to the server.  Then you need a way to find your public IP address and that is easily done by setting up an account on a public dynamic IP server.  I don&#x27;t do this at the moment but I used to run my own mail server that way (I stopped because it is to hard to find someone to relay my mail now).
