Logging traffic on Win2k loopback adaptor

I'm trying to log traffic between a client and server running on the same
Win2k machine.
I've installed the loopback adaptor and verified the client can connect to
the server using the loopback address (169.254.25.129).
However, I can't get Snort (v2.1.3) to log any traffic on that adaptor.
Can Snort log local traffic on Win2k? If so, what have I missed?
I've tried using Snort's -I option to set the interface but that doesn't
help either.
My rules do log traffic from a remote machine so I'm happy that's doing what
I want it to.
Below are my rules, ipconfig output and Snort -W output.
Any help much appreciated.
Thanks in advance
