I am having a problem deciding on a correct routing for this question,
please feel free to direct me to a more appropriate place if you feel
this is an off-topic request.

I have a small home network with two BSD machines running -STABLE 
from Feb 13:

BSD (192.168.0.4)--Netgear(hostname switch=192.168.0.1)--BSD (hostname kot=192.168.0.2)
kot has a 3C905C-TX-M network card.
Default route is 192.168.0.1 for both machines.

This setup worked for about a month, but suddenly stopped working today for no
apparent reason.    kot obtains a fixed IP from switch via dhcp; and
after that I cannot connect to switch from kot, i.e. pings don't work, etc.
The weird thing is that tcpdump still reports icmp echo request/reply exchange, 
but ping command reports no replies:

# ping switch
PING switch (192.168.0.1): 56 data bytes
^C

# tcpdump
tcpdump: listening on xl0

22:44:21.163670 switch > 192.168.0.2: icmp: echo reply

If I change kot's address to 192.168.0.3, everything works normal as before.

Why would not ping command report icmp replies that tcpdump shows, any ideas?
