I'm having touble setting up NAT translations in what appears to be a simple senario. From the router I'm able to ping to the outside world, though clients behind ge0/1 are not.
[Internal LAN 10.10.10.0/26] -> [ ge 0/1 10.10.10.1] ( cisco 2911) -> [ ge 0/0 external.ip.address] -> [internet]
Attached is the router config, any thoughts?

I don't see any thing wrong in your configuration.
Can you try to move "ip nat inside" command and then apply it back to see if it can fix it?
If not, maybe run some debug like "debug ip nat" and "debug ip packet" .

Thanks Yudong,
Still no luck, here's the 'debug ip packet' output from a host pinging to the outside world:

'debug ip nat' has no output

If removing/reapplying "ip nat" command could not fix the issue and there is no "debug ip nat" output, it is most likely a bug. I would suggest you to try a latest code.
