Cisco 851 - from outside, I Can ping inside interface, but not outside...?

Just a bit of a strange question here....
When I first setup this router, from outside, I could ping both fe04 and Vlan1.
After running for 3 or 4 days I could no longer PING the fe04, but communication was fine.
After a reboot, then same scenario exists - just kind of weird.

Any ideas?

First off, you have an access-list configured on the interface, but the ACL doesn't seem to exist!
Something must have changed a few days ago. I notice you have to config archive configured (although no path specified); have a look at the config from a few days ago and see if you can see a difference, if it indeed exists.
If you don't need the ACL remove the lines from the interfaces and the VTY lines. If you do need it, recreate it.

Let me know how it goes!
