<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>It
seems that there are some strange behavior in the logs that you have
sent.</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT size=2 face=Arial><FONT
color=#0000ff>One very strange thing is that there are many arp requests from

ARP Who has <FONT

192.168.100.219</FONT></FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>(see
for example packet #8, 10, 11,14,16, 19 and many more).</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2
face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>This
is strange in two ways:</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>1) Why
is he asking for address 0.0.0.0 and not a real address?</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>2) Why
isn't this a broadcast message?</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2
face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>I
guess that this mal-formed packet explains why there is no response:
192.168.100.219 doesn't know where the remote address is.</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2
face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN class=564311010-09072009><FONT size=2 face=Arial><FONT
color=#0000ff>The second strange thing is that all of a sudden, on packet #48
192.168.100.219 starts sending data to <FONT size=3
face="Times New Roman">192.168.100.250.</FONT></FONT></FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT size=2 face=Arial><FONT color=#0000ff
size=3 face="Times New Roman">I guess that this can be explained since on packet
47, there was an arp request from 219 to 250. There are two strange thing
here:</FONT></FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT size=2 face=Arial><FONT color=#0000ff
size=3 face="Times New Roman">1) This is a unicast packet and not a
broadcast packet.</FONT></FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff>2) The same information
could have being also learned at frame #4. Why does he has to wait for packet
#47?</FONT></SPAN></DIV>
<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>This
packet is being answered and from here all is well. (ping
passes).</FONT></SPAN></DIV>

<DIV><SPAN class=564311010-09072009><FONT color=#0000ff size=2 face=Arial>In
order for me to better understand this situation, can you please repeat the
experiment and send me the wireshark log of <FONT color=#ff0000>both</FONT>
sides?</FONT></SPAN></DIV>
