When I try to do ordinary ping for local address in interface em0, ping shows 100% lost

master:[root] 102>ping
PING ( 56 data bytes
--- ping statistics ---
2 packets transmitted, 0 packets received, 100.0% packet loss

When I do the same, but with hardly specified source address, all OK

master:[root] 103>ping -S
PING ( from 56 data bytes
64 bytes from icmp_seq=0 ttl=64 time=0.028 ms
64 bytes from icmp_seq=1 ttl=64 time=0.028 ms
--- ping statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.028/0.028/0.028/0.000 ms

Install FreeBSD-8.x.
Configure any local interface.
Try to ping it.
You falied.
