Hi, Peter.

GW-77.93.52.9/29 <---------> 77.93.52.10/29-MyServer
                               00:1b:21:45:da:b8

I have change LAN and not it is:
GW-77.93.52.9/29 <---------> 77.93.52.10/29-MyServer
                               00:30:67:5a:44:72

ping 77.93.52.9
^C

77.93.52.9 thinks that 77.93.52.10 have old MAC 00:1b:21:45:da:b8
Why freebsd do not answer for 'who-has' packet?
