Hello,
I am facing a very strange problem. Actaully, i have a server in wich Netgear Firewall is attached with a Internet Connection.
Since last few days, Internet is working good, when i used it in Laptop with out connecting firewall. But when i tries to connect internet with firewall on my server, its not working. Even i tried to open Firewall settings, firewall login page was not opened. I tried 192.168.0.1(bydefaut one) and the another one(which was working last time) to open the page, but it displays a blank page.

Now, i am not able to open firewall page, and im not understanding what happen with my firewall.
So, i want to ask what should i do in this situation?
