Firewall Entries



Greetings,

Over the last week, I have been configuring the Firewall service on
our XServe, and I think I have it just about right, except for one
small thing.  We're on a University Campus, so our firewall is
secondary to the main University firewall.  Also, every client on
campus has a globally-accessible IP address (i.e. 131.162...) 
However, in my firewall logs, I'm getting a lot of entries that look
like this:

Sep 23 16:31:17 server-host kernel: ipfw: 63300 Deny P:2 192.168.1.208
224.0.1.22 in via en0
Sep 23 16:35:17 server-host kernel: ipfw: 63300 Deny P:2 192.168.1.208
239.255.255.250 in via en0
Sep 23 16:36:18 server-host kernel: ipfw: 63300 Deny P:2 192.168.1.208
239.255.255.250 in via en0
Sep 23 16:37:18 server-host kernel: ipfw: 63300 Deny P:2 192.168.1.208
239.255.255.250 in via en0
Sep 23 16:43:19 server-host kernel: ipfw: 63300 Deny P:2 192.168.1.208
224.0.1.22 in via en0
Sep 24 09:35:07 server-host kernel: ipfw: 63300 Deny P:2
169.254.83.112 239.255.255.250 in via en0

Does anyone have any idea what this means?  I know that the "Deny"
means that the firewall is stopping them.  I also know that 192.168 is
a private-range IP, but is 169.254?

I don't think it's a critical error, but I'm just curious as to what's
causing it... I'm getting a lot of them.

Thanks,

Andrew
