No internet Connection

[Sobowolf]

Hello,

I hope anbybody can help me. I am really frustrated. My Pf sense is connected to a belkin router and gets his WAn over DHCP.
The Internet access was functioning until yesterday. Now I have problems to access the internet. When I connect to the Belkin router I can access the internet. But there is a problem with my pfsense.
Has anybody any ideas how I can fix ths problem?

Greetings
