Connectivity with a Cisco 2505

[catatung]

Hey,

I am trying to put a cisco 2505 into a small isolated network. My configuration is shown at the end of this email:

Once I set up this configuration, pings can go through. I am doing it on the initial startup with the menu questions.

at this point:

Use this configuration? [yes/no]: y
Building configuration... [OK]
Use the enabled mode 'configure' command to modify this configuration.

pings work.. but only for about 5 seconds. Then this comes up.

Press RETURN to get started!

Ethernet0 is said to be up... But I can't ping it. I can't even ping it from itself.. any ideas?
