Default Cisco 1841 router - can't source ping inside to internet


Hi all,

I just installed a 1841 router with an internet T1 as it's primary connection and a DSL for the backup. For some odd reason, I can't source ping fa0/1 (LAN interface) to any public IP addresses (4.2.2.2 for example). Now the users on that subnet are able to access the internet and ping any public IP addresses just fine. I really need to be able to source ping from the LAN interface for failover testing. Please advise.

------------------------------------------------

router# ping 4.2.2.2 source fastEthernet 0/1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:
Packet sent with a source address of 192.168.60.254
.....
Success rate is 0 percent (0/5)
