I have router based on OpenWRT which has dnsmasq 2.59. Inside my local area network I have a NS server bind. This server has internal and external views for a couple of my domains. My router forwards port 53 TCP and UDP from outside IP (router WAN) to this server. For the external clients everything works fine.

In order to organize the internal view, I decided to add the exception to

/etc/dnsmasq.conf

server=/mydomain1.com/192.168.1.1
server=/mydomain2.com/192.168.1.1
server=/mydomain3.com/192.168.1.1

(192.168.1.1 - IP address of the NS server)

According to dnsmasq manstrong text:

More specific domains take precendence over less specific domains, so: --server=/google.com/1.2.3.4 --server=/www.google.com/2.3.4.5 will send queries for *.google.com to 1.2.3.4, except *www.google.com, which will go to 2.3.4.5

this domain name with all the sub-domains is supposed to be forward to my NS server.

Everything works (SOA, NS, MX, CNAME, TXT, SRV etc.) except for A-record:

# nslookup -type=a mydomain1.com

Server:         192.168.1.100
Address:        192.168.1.100#53

*** Can't find mydomain1.com: No answer

192.168.1.100 - IP address of my router (dnsmasq)

However, I can get the answer for the TXT-record query:

# nslookup -type=txt mydomain1.com
Server:         192.168.1.100
Address:        192.168.1.100#53

mydomain1.com        text = "v=spf1 include:mydomain1.com -all"

When I just specify the local IP of my NS server (direct access to the server without using dnsmasq) then the results are:

# nslookup -type=a mydomain1.com 192.168.1.1

Server:         192.168.1.1
Address:        192.168.1.1#53

Name:   mydomain1.com
Address: 192.168.1.1

There is a similar situation with the MX-record:

C:\>nslookup -type=mx mydomain1.com
Server:  router.lan
Address:  192.168.1.100

mydomain1.com         MX preference = 10, mail exchanger = mail.mydomain1.com
mydomain1.com         nameserver = ns.mydomain1.com
mail.mydomain1.com   internet address = 192.168.1.1
ns.mydomain1.com     internet address = 192.168.1.1

C:\>nslookup -type=a mail.mydomain1.com
Server:  router.lan
Address:  192.168.1.100

*** No address (A) records available for mail.mydomain1.com

This is a dig result:

# dig +nocmd mydomain1.com any +multiline +noall +answer

                                )

mydomain1.com.          604800 IN MX 10 mail.mydomain1.com.
mydomain1.com.          3600 IN TXT "v=spf1 include:mydomain1.com -all"

When I try to ping:

# ping mydomain1.com
ping: cannot resolve mydomain1.com: Unknown host

Is it a bug of dnsmasq 2.59? How to manage this problem?
