That looks fine, IP and network are okay, and the interface is UP.

Does 'arp -an' show it managing to get ARP responses?

The hosts you are pinging should also have those host in their ARP tables.

If you're not getting ARP lookups then it sounds like something more
fundamental, such as the card not working, or cable issues.

Also, make sure the box doesn't have any firewalling enabled, ipfw and
ipf both have 'default deny' kernel options.
