unable to ping out of a new install

[Chip Wiegand]

I just installed 5.3 on a laptop and am able to ping it, but it cannot 
ping anything else. When I enter the ping <ipaddress> command the curser 
moves down a line then nothing. It doesn't even time out. Just nothing. 
The box will reply to a ping from another box on the network though. Is 
there something new in 5.3 that I have to do to allow it to send a ping?
Thanks,
Chip
