[Winpcap-users] ARP problem, works with XP but not with Vista..

[Janne Heikkinen]

I have application running on XP and I have added IP address
manually with arp command like this:

   arp -s 10.68.23.47 aa-cd-ef-12-34-56

Now when the application sends UDP packet to that IP address
I see it with WinDump.

But when I try the same application under Vista I don't see anything
with WinDump.

Running "arp -a" gives about the interface in question:

   Interface: 169.254.45.253 --- 0x10
     Internet Address      Physical Address      Type
     10.68.23.47           aa-cd-ef-12-34-56     static
     169.254.255.255       ff-ff-ff-ff-ff-ff     static
     224.0.0.22            01-00-5e-00-00-16     static
     224.0.0.252           01-00-5e-00-00-fc     static
     239.255.255.250       01-00-5e-7f-ff-fa     static
     255.255.255.255       ff-ff-ff-ff-ff-ff     static

And the application is certainly using interface 169.254.45.253
to send to destination 10.68.23.47.
