Problem is slightly different now. Seems that the details have gone in (as we have now established). It also says that it is active on the menu, however when you press to look in the log file you get the following message:
w:INADYN: Error validating DYNDNS svr answer. Check usr,pass,hostname!
Now I know that all of the details that I have entered are correct, however it deffo isnt working when you try and connect to it via the dns name that no-ip gives you, just times out. I have checked that the firewall is port forwarding and this is in place.
Now im totally at a loss to what is causing this one.
