DHCPD does not update local BIND

sirtow

Hi all, i spent past couple of hours debugging the issue with no success.
I have dhcp server configured to send updates to bind server ( im on pfsense 2.4.4-RELEASE).
All of my static mappings are correctly updated by dhcp server and i can see matching records in named zone.
The problem is that no other hosts besides the static ones are being updated in NAMED. I see DHCPREQUEST and DHCPACK in the logs with correct host name e.g "DHCPREQUEST for 172.16.200.148 from xx:xx:xx (db) via re1" but no dns updates are triggered.
So far i tried to play with DDNS Client Updates and "Enable registration of DHCP client names in DNS" options in addition of changing "dhclient.conf" on my client host.

i tried the following options in dhclient.conf:

option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;

send host-name = gethostname();
request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, domain-search, host-name,
        dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
        netbios-name-servers, netbios-scope, interface-mtu,
        rfc3442-classless-static-routes, ntp-servers;
send fqdn.server-update off;
timeout 300;

and without sending host-name :

option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
send host-name = gethostname();
request subnet-mask, broadcast-address, time-offset, routers,
        netbios-name-servers, netbios-scope, interface-mtu,
        rfc3442-classless-static-routes, ntp-servers;
send fqdn.server-update off;
timeout 300;

but still no luck...

What am i missing?
Thank you!
