Hello,
The problem is that any client inadvertently or intentionally put cable which runs from the modem. Rather than add it to the WAN port of the LAN insert automatically consequently they begin to transmit DHCP in the system, which consequently most modems remain in status: 0.0.0.0 DHCP offer.
I tried to solve this problem but without success, I wish that someone with you to help.
With respect ....

You could pop something like this into your cm config file :
SnmpMibObject docsDevFilterIpDefault.0 Integer 2; /* accept */
SnmpMibObject docsDevFilterIpIfIndex.1 Integer 1 ;
SnmpMibObject docsDevFilterIpDirection.1 Integer 1; /* inbound */
SnmpMibObject docsDevFilterIpProtocol.1 Integer 17 ; /* UDP */
SnmpMibObject docsDevFilterIpSourcePortLow.1 Integer 67 ; /* bootp server */
SnmpMibObject docsDevFilterIpSourcePortHigh.1 Integer 67 ;
SnmpMibObject docsDevFilterIpDestPortLow.1 Integer 68 ; /* bootp client */
SnmpMibObject docsDevFilterIpDestPortHigh.1 Integer 68 ;
SnmpMibObject docsDevFilterIpStatus.1 Integer 4; /* createAndGo */
