Setup Cisco router to access internet

Hi Everyone,


I have a cisco router and I'd like to set it up so my PCs can get the internet from it but it doesn't seem to work for me.


From router CLI, I can ping 4.2.2.2 and other IP addresses but my PC which connected to int fa3 can't access to the internet. The PC gets the 10.10.10.2 address from DHCP on this router and DNS is 8.8.8.8. What am I missing? Any ideas? Thanks.

Setup Cisco router to access internet

Hi Andy,

I'm not seeing any config for outside ( WAN) IP to which inside gets translated...

Also, can you please let us know on which port your WAN connection is ??
