Trying to do a basic config with a Cisco 871 with IOS c870-advsecurityk9-mz.124-24.T4.bin. Connecting to ISP via DHCP. I get an IP from the ISP and can ping the ISP gateway from the WAN interface. My internal computer receives an IP from the 871 and can ping the ISP gateway as well, but that's as far as the traffic goes. I must be missing something in my config....Any suggestions? I think it is either a NAT, or ACL issue...

Re: Basic connectivity to 871 router not working...
You were already receiving a default route from your ISP with dhcp( installing a default static route with an AD of 254) so just removing your static default route command should do the trick, because here you were overriding this route with one with a better AD but your new default static route was pointing to the interface which was fastethernet and so if the ISP gateway was not configured for proxy arp( and it shouldn't be) then it won't work but if you had pointed towards next hop( ISP gateway) it should have worked.
