Weird entries in my firewall

Subject: Weird entries in my firewall
Date: 30 Aug 2005 15:31:01 -0000
Hi list,

I've been getting these weird entries in my firewall (iptables) for a while...

BLOCK 12:29:37.371982 OPT1 192.168.0.50, port 2401 255.255.255.255, port 712 
UDP 

Now, the source is the internal IP of my server, which is not connected to the 
firewall.  It's as if the traffic goes through the external interface using the 
internal ip, and always broadcasts to port 712.  Two of my servers are doing 
that.

Has anyone ever seen something like this?  It has me completely stumped.

Thanks!
