Hi List.
Unfortunately we have few docsis customer, who would use more than 1
CPE IP-address behind theirs cable modems at the same time.
Because i use everywhere static host decl in my dhcp config, i dont
know whether i can do this with isc dhcp?
I would like to do this with the 'host-identifier' option.
1. attempt:
host cpe_1234 {
host-identifier option agent.remote-id 00:11:22:33:44:55;
fixed-address 172.27.0.10, 172.27.0.20;
}
But this does not work, because: (from manual dhcpd.conf)
"it will be assigned the address that corresponds to the network on
which it is booting."
2. attempt:
host cpe_1234_1 {
host-identifier option agent.remote-id 00:11:22:33:44:55;
fixed-address 172.27.0.10;
}
host cpe_1234_2 {
host-identifier option agent.remote-id 00:11:22:33:44:55;
fixed-address 172.27.0.20;
}
This method does not work also, because the dhcp server always deal out
the first fixed IP (172.27.0.10)
and will be IP address conflict.
Can anybody give me some information how can i manage this "problem"?
