Cisco 1921 Router, Truble setting up NAT

Erik Hennerfors
Level 1
Level 1

I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.

The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.

"sh ip interface brief" - shows the following:

Interface                  IP-Address      OK? Method Status                Protocol

GigabitEthernet0/0         85.*.*.*   YES DHCP   up                    up

GigabitEthernet0/1         10.0.0.1        YES manual up                    up

NVI0                       85.*.*.*   YES unset  up                    up

The GigabitEthernet0/0 gets its ip-address from my ISP.

"sh ip nat translations" - is showing nothing.

Here is my config:
