One NIC with a subnet for known clients and another one for unknown clients
I'd like on one network card to manage two subnets:
- One dedicated to known clients
- One dedicated to unknown clients
Then, I'd be able to build on my router some iptable rules to limit unknown client’s access to the other subnet.
In the current implementation of ISC DHCPD, I can only isolate guests on a pool in a subnet: Known clients in a range, 192.168.0.1 -> 192.168.0.10 Unknown clients in another range of the same subnet, 192.168.0.11 -> 192.168.0.20 My router can’t filter packets since there is only one subnet
Expected configuration:
shared-network xxx {
subnet xxx ... {
...
deny unknown-clients;
}
subnet yyy ... {
allow unknown-clients;
}
}
