Don't worry guys, he PMed me as he was worried about putting his IPs up, and what it is about is that there is a second router, after the modem.
When port forwarding, you need to forward from the modem usually.
However in this case, as there's a router, as well as the modem, you need to do 2 sets of port forwarding rules. One on the modem, forwarding to the router, then on the router, to the machine that is hosting.
What he was doing, was putting the host machines address, into the modem, effectively giving a different IP class, on the port forwarding, which in turn gave this error saying the IP was invalid.
