to add more info:
I have the issue that my ISP blocks port 80 and changes my IP a little now and then, so what I have done to get around this on my other sites is to listen on port 8081 and use a dynamic ip from no-ip and linked that to the domain.
so to help me in this case the no-ip is tueweb.no-ip.org and the domain is tue.nu
so with this information do anyone know what I should set those values to to get it working both externally and internally?
