just an idea:
a possible cause woud be that there is another host using this IP address.
have you waited long enough after the reboot to see if problems do not 
reappear?
indeed, ethernet packets are addressed using the MAC address, so if *.9 was
assigned to another host, packets will be sent to this host.

To check that, use *.8, and try to ping *.9, or check the arp table of 
another host
(arp -a).

also, use tcpdump/tcpshow to see if packets are sent in both directions. 
This actually will show
you the ethernet address used in the packets.


hope this helps,
mouss
