This will sound errily similar to another post on this site.
I'm also new to Cisco router configuring. We are trying to configue a 1921 to communicate to our local ISP's gateway and a private network.
From the router we can ping the external dns server and we can also ping our internal network. However we can not ping from a pc on the internal network to the dns server on the external network.
I have attached our code..
Any help is greatly appreciated...

you haven't configure NAT rule on you router, you need something like
access-list 101 permit ip 192.168.1.0 0.0.0.255 any
ip nat source list 101 interface gi0/1 overload
