RT-AC68U / Merlin 378.56_2 Zone transfer

[Tuinkabouter]

Hello all,

As being a new user to Merlin I'm running into something where Google can't help me for the moment.

My setup is as follows:

- One Debian server connected to the Internet, running Samba, Bind and OpenVPN in subnet 192.168.50.0/24
- 5 RT-AC68U routers to connect 5 small offices to each other with the OpenVPN client. The routers are each setup to serve a different subnet to the client computers with DHCP. Router 1 serves 192.168.50.0/24, Router 2 serves 192.168.52.0/24 and so on.

The debian box serves 192.168.50.0/24 to its clients by DHCP, where isc-dhcp-server dynamically updates a BIND zone for an FQDN, and for the 192.168.50.0/24 it works perfectly, i can ping clientname.fqdn.tld from all connected VPN-sites, however, it only resolves the debian-clients.

What I want to achieve is that the Merlin-routers does the same trick for its subnet, so that all network clients can resolve all computers on all subnets to its name.

When I google for DDNS on Merlin boxes it's allways updating the WAN-ip to a DynDNS-like but I want to update/store the LAN ip's with their hostnames in my BIND-server. Is there a way to do this?

Kind regards,
Tuinkabouter

Here's the part from the debian dhcp config:

[dhcpd.conf]

authoritative;

option domain-name "fqdn.tld";
option domain-name-servers 192.168.50.1;

ddns-updates on;
ddns-update-style interim;
ignore client-updates;
update-static-leases on;

default-lease-time 600;
max-lease-time 7200;
log-facility local7;

include "/etc/dhcp/ddns.key";

zone fqdn.tld. {
  primary 127.0.0.1;
  key DDNS_UPDATE;
}

zone 50.168.192.in-addr.arpa. {
  primary 127.0.0.1;
  key DDNS_UPDATE;
}

[/dhcpd.conf]

Can I somehow use this on Merlin?

I've found what i'm looking for...

apparently I want to do a thing called "zone forwarding".

The needed rules in dnsmasq.conf.add would be something like:

auth-server=knes.computerdokter-groenlo.nl
auth-zone=knes.computerdokter-groenlo.nl
auth-sec-servers=192.168.50.1
auth-peer=192.168.50.1

However, when I reboot and look at the syslog I see:

Aug  1 02:00:19 custom config: Appending content of /jffs/configs/dnsmasq.conf.add.
Aug  1 02:00:20 dnsmasq[638]: unsupported option (check that dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support) at line 26 of /etc/dnsmasq.conf
Aug  1 02:00:20 dnsmasq[638]: FAILED to start up

Does this mean zone transfers aren't possible in Merlin?
