DG8245W2-10 Port 80

You mean to access the web server behind the home router via the internet？

Yes from outside, I have a webserver running on my Qnap NAS, When I try to forwarding port 80 to my Qnap its just giving me an error, I need it when Im at work.

Hello, friend, this feature you need is not possible, it involves your security and privacy, some features have been prevented
Thank you

Not possible? You mean that everyone with DG8245W2-10 router cant have there own server running? If that so I need another adsl router, I thought the DG8245W2-10 was a good one with plenty of option, tuning etc

Hello, if you really need to implement this function, you can do the following:
1. If you are an enterprise user, cancel the Layer 2 isolation of the ONT on the OLT.
2. If you are a carrier user, contact your ISP to enable this function.
Note: There are security risks in the scenario you want.

Problem solved! 

I simply use another port for my webserver, ie I setup portforwarding 81 to my server and when I connect from outside I just using "www.mysite.com:81 so thats all good for now!

Tnx for trying to help..

You're amazing.
