That's still not telling me the error message you receive.
Are you getting a 404, what is the exact wording of the error message?
If your browser cannot open Google, is that the browsers fault? I'd first check connectivity, in particular NAT.
Download a portable Apache-server and put it on USB. Start that on the machine that you are trying to reach. That way you can verify whether the computer can be found and the TCP settings/firwall/router is correct. I'm going to guess that the translation of the external IP to an internal IP is incorrect.
Hi Mr.GuyThiebaut and Mr.Eddy Vluggen
Thank you very much for your reply and sorry for my delay. Right now I´m out until the next monday. I can´t prove anything more. As soon as I come back I´m going to prove it and then I´ll reply
