Hi!


What we are doung is the following:

First the subnet looks like that:

subnet 10.91.120.0 netmask 255.255.255.0 {
        option routers 10.91.120.254;
        option domain-name-servers 8.8.8.8;
        pool {
                failover peer "dhcp-failover";
                deny dynamic bootp clients;
                range 10.91.120.2 10.91.120.252
}
               

When we want t reserve an ip address, we add the host block:

host a.lraroth.de-005056b22f2c {
hardware ethernet 00:50:56:b2:2f:2c;
fixed-address 10.91.120.7;
}

...and change the range to:

subnet 10.91.120.0 netmask 255.255.255.0 {
        option routers 10.91.120.254;
        option domain-name-servers 8.8.8.8;
        pool {
                failover peer "dhcp-failover";
                deny dynamic bootp clients;
                range 10.91.120.2 10.91.120.6;
                range 10.91.120.8 10.91.120.252;
}

Could that be a problem?

Frank
