[pkg-dhcp-devel] Bug#603638: isc-dhcp-server shared network with fixed and dynamic ip pools

[Laszlo Fekete]

Package: isc-dhcp-server
Version: 4.1.1-P1-12

I have shared networks with fixed and dynamic ip ranges within the same
shared network.
Set "deny unknown-clients" in static pool and "deny known-clients" in
dynamic pool. But if a client has dynamic ip and later set a fixed
address within the same shared-network, sometimes dhcp server give him
again a dynamic ip, not the static.

shared-network "net2" {

        subnet 182.16.20.128 netmask 255.255.255.192 {
            pool {
                range 182.16.20.129 182.16.20.189;
                deny unknown-clients;
            }

                authoritative;

                option          broadcast-address 182.16.20.191;
                option          routers 182.16.20.190;
               
        }


        subnet 192.168.120.128 netmask 255.255.255.192 {
            pool {
                range 192.168.120.129 192.168.120.189;
                deny known-clients;

            }

                authoritative;

                deny duplicates;

                option          broadcast-address 192.168.120.191;
                option          routers 192.168.120.190;

        }
}

host 182.16.20.161 { hardware ethernet 00:1c:23:aa:91:b2; fixed-address
182.16.20.161; }
