Hi,

I had last times some strange hangs of my firewall and now I managed  
it to transfer logs via rsyslog. And would appreciate some opinion for  
the following messages and If I am right or not:

Feb  3 05:46:40 roch.ring.ier dhclient: DHCPREQUEST on vr0 to  
172.30.52.16 port 67

IN my opinion the leases of DHCP-Server of my provider are only in the  
range of about 30 Minutes here given in seconds. But what about the  
ipmon-Messages? I saw in the Internet some remarks about ipmon what is  
surveilling the ip-Adresses - But it was not really good explained and  
I didnt understand really..

Thanks in advance for Your replay
