I am having an issue accessing the internet from a PC on the LAN. I have configured the PC with the gateway of the router infront of the ISP to test. I can ping from the router to google or any other internet IP. From the PC I can ping to the GIG0/1 (Inside LAN IP) and the GIG0/0 (Outside WAN IP going to ISP) but I can't ping the Next Hop IP of the ISP or anything past that. If I do a trace route from the PC to the google IP address it hits the GIG0/1 Inside LAN IP Address but fails from there. Here is a cut down snap shot of the router config, any help would be appreciated. Thank you.

When someone describes a problem where a PC on the LAN can ping the router interfaces but not the ISP my first guess at the problem is a failure to configure address translation. But the ip nat inside and ip nat outside look ok. And the ip nat source list seems to be correct. The default route seems ok, and you say that the router can access outside addresses so that seems to confirm that routing is ok. So right now I am a bit puzzled at what the problem might be. If you try to ping outside to google or whatever using an extended ping and specifying the address of gig0/1 does it still work ok?
You could configure "debug ip packet" and "debug ip nat" on the router and try the ping from you PC. Record the output displayed on the router console and post it. Remember to use "terminal monitor" if you are telnetted to the router.
Someone posted to this with what corrected the issue but it is gone off the discussion. What was suggested was to remove the "ip nat source list 1 interface GigabitEthernet0/0 overload" and add "ip nat inside source list 1 interface GigabitEthernet0/0 overload" and that fixed the issue. Not sure what happened to his posting though. Thank you everyone that has been replying, it has been very helpful.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
