I have an error on the log:
Feb 6 11:53:56 ralinux dhcpd: Unable to add forward map from RA4.ralab.com to 192.168.0.99: timed out

I have read all the docs and cannot figure it out.

Here is the named.conf

acl "home" { 192.168.0.0/24; 127.0.0.1; };

include "/etc/rndc.key";

options {
directory "/var/lib/named";
allow-query { "home"; };
allow-recursion { 192.168.0.0/24; 127.0.0.1; };
# forwarders { 192.168.0.1; };
};

controls {
inet 127.0.0.1 allow { localhost; } keys { rndc-key; };
};


zone "localhost" {
type master;
file "localhost.zone";
allow-update { none; };
notify no;
};


zone "0.0.127.in-addr.arpa" {
type master;
file "master/db.localhost.rev";
allow-update { none; };
notify no;
};

zone "ralab.com" {
type master;
file "master/ralab.zone";
allow-update { key "rndc-key"; };
notify yes;
};

zone "0.168.192.in-addr.arpa" {
type master;
file "master/db.192.168.0.rev";
allow-update { key "rndc-key"; };
notify yes;
};

zone "." {
type hint;
file "root.hint";
};

Here is the dhcpd.conf
option domain-name "ralab.com";
option domain-name-servers 192.168.0.13;
option routers 192.168.0.1;
authoritative;

key rndc-key {

};

zone 0.168.192.in-addr.arpa. {
primary 127.0.0.1;
key rndc-key;
}

subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.22 192.168.0.99;
}

zone ralab.com {
primary 192.168.0.13;
key rndc-key;
}

I have been beating my head on this for days.
Thanks for your help.
