Strange ipfw messages in /var/log/messages

[Sascha Wildner <saw@xxxxxxxxx>]

Hi folks,

from time to time I get strange fragments of ipfw messages in 
/var/log/messages instead of /var/log/security. It looks like this:

Aug 12 19:35:26 <kern.crit> yoyodyne /kernel: 28172 in via tun0
Aug 12 19:35:29 <kern.crit> yoyodyne /kernel: in via tun0

Aug 14 21:47:58 <kern.crit> yoyodyne /kernel: .4:25600 
213.196.245.18:55412 in via tun0
Aug 14 21:48:01 <kern.emerg> yoyodyne /kernel: .4:39206 
213.196.245.18:5490 in via tun0

Also note facility and level (normally it's security.info).

Anyone know what's the problem here?

Regards,
Sascha
