Thanks, but not work.
The MTA Scientific Atlanta DPC2203 does'nt send the DISCOVERY for the 
DHCP, already the MTA Arris sends the DISCOVERY, the DHCP answers with 
the OFFER, but the process does not continue:
Oct 29 13:47:01 server dhcpd: DHCPDISCOVER from 00:15:a2:19:dd:7e via 
10.10.255.254
Oct 29 13:47:01 server dhcpd: DHCPOFFER on 10.8.0.20 to 
00:15:a2:19:dd:7e via 10.10.255.254

* Both Cable Modem receives the IP and get the archive in the TFTP, but 
the MTA not.

What to make to solve ?

Thanks

Daniel
