I have a version 15.05 OpenWRT router which is a member of a local network. This network has its own DHCP and DNS servers which dnsmasq should automatically use for domain name resolution. However host names for members of the lan are not resolving through dnsmasq.
/etc/init.d/dnsmasq stop which allowed these names to resolve on the router. However this stopped all domain name resolution on my laptop while connected to the router.
I'd like dnsmasq to not filter local domain names from its results, and for it to use the proper DNS servers (I belive it does), or to find a way to live without dnsmasq by passing on upstream DNS server IP addresses to clients of the router. (I would prefer to not hard code DNS server IP addresses so that the router can be used in other environments without reconfiguration.)
I disabled some of the options below because they ensure "... that requests for these local host names (and the reverse lookup) never get forwarded to the upstream DNS servers."  However This did not solve my issues with dnsmasq.
root@wrt0:~# cat /etc/config/dhcp config dnsmasq #option domainneeded '1' option domainneeded '0' #option boguspriv '1' option boguspriv '0' option filterwin2k '0' #option localise_queries '1' option localise_queries '0' option rebind_protection '1' option rebind_localhost '1' option local '/lan/' option domain 'lan' #option expandhosts '1' option expandhosts '0' option nonegcache '0' #option authoritative '1' option authoritative '0' option readethers '1' option leasefile '/tmp/dhcp.leases' option resolvfile '/tmp/resolv.conf.auto' option localservice '1' ... root@wrt0:~# cat /etc/config/network ... config interface 'lan' option ifname 'eth1' option type 'bridge' option proto 'static' option ipaddr '10.0.2.1' option netmask '255.255.255.0' ... root@wrt0:~# cat /etc/resolv.conf search lan nameserver 127.0.0.1 root@wrt0:~# cat /tmp/resolv.conf.auto # Interface wan nameserver 192.168.0.10 nameserver 192.168.0.25 search office.website.org search website.org
When resolving local names using dnsqmasq, resolution fails:
root@wrt0:~# nslookup abc.office.website.org Server: 127.0.0.1 Address 1: 127.0.0.1 localhost nslookup: can't resolve 'abc.office.website.org': Name or service not known
When bypassing dnsmasq, resolution works fine:
root@wrt0:~# nslookup abc.office.website.org 192.168.0.10 Server: 192.168.0.10 Address 1: 192.168.0.10 resolver.office.website.org Name: abc.office.website.org Address 1: 192.168.0.32 abc.office.website.org
dnsmasq looks up internet-facing servers without a hitch:
root@wrt0:~# nslookup abc.website.org Server: 127.0.0.1 Address 1: 127.0.0.1 localhost Name: abc.website.org Address 1: 208.xxx.xxx.xxx xyz.website.org
Do you have any ideas about how I may bypass dnsmasq's filtering, or bypass dnsmasq altogether? Thanks! : D
