No internet connection

Hello,

i'm doing a project for school and we are using a Cisco 2950 switch and a Cisco 2800 series router. I have configured some settings but i can't get a connection to the internet, through the switch. I can send a ping from the router to for example google.com, this works!

The IP address (10.1.0.254) used by the static default route is a Sonicwall which is placed between the router and the wall-outled.

I hope somebody can help me with this problem.

Kind regards,

 

Patrick

Thanks Sandy, 

This worked out great for me!

Sadly the button for  Correct Answer doesn't work, it sends me to a site where i don't have access to.

But thank you very much!
