How? What exactly did you do? Are these addresses static or assigned by
a DHCP server?

Why do you think there's a problem with ssh if you can't use ping? In
most cases if ping doesn't work, nothing works, assuming pings aren't
being filtered on the way to or from the target. "traceroute <target>"
can be helpful here.

You might also try "arp" to see if the IP<->MAC mapping is correct.
