[Dnsmasq-discuss] how to handle the local domain (A, PTR)

[Wojtek Swiatek]

Hello,

I set up dnsmasq on my home network to replace the isc/bind legacy
system :) when changing the architecture. The setup relies on a debian
which acts as the router/firewall/"master of all truth" (DNS, ntp,
...):
- an ADSL access to Internet with the public IP assigned to eth1
- a wired network 192.168.0.0/24 bound to eth0 (which has the
192.168.0.10 address)
- a wired network 192.168.1.0/24 bound to wlan3 (which has the
192.168.1.10 address)
- the domain name for the internal network is "home"
- firewalling is handled by shorewall

The dnsmasq configuration is:

domain-needed
bogus-priv
local=/home/
expand-hosts
domain=home
dhcp-range=eth1,192.168.0.70,192.168.0.150,240h,set:lan
dhcp-range=wlan3,192.168.1.10,192.168.1.50,240h,set:wifi
dhcp-option=42,0.0.0.0
dhcp-option=27,1
dhcp-option=19,0           # option ip-forwarding off
dhcp-option=44,0.0.0.0     # set netbios-over-TCP/IP nameserver(s) aka
WINS server(s)
dhcp-option=45,0.0.0.0     # netbios datagram distribution server
dhcp-option=46,8           # netbios node type
dhcp-option=252,"\n"
dhcp-option=vendor:MSFT,2,1i
dhcp-authoritative


What works:
- clients in the subnets (both wired and wireless) get IP addresses
via DHCP in the expected ranges
- external (Internet = forwarded) DNS resolution works for these
clients and for the server

What does not work: the "home" domain name does not seem to be handled:
  * /etc/hosts has a
    192.168.0.10 server.home
   entry which is not used, ie. "dig server" does not return the name,
"dig server.home" does not either.
  * PTR records for DHCP-assigned names are not there

I am sure that this is something obvious but I am brand new to dnsmasq
and would appreciate very much any pointers.

Thank you,
Wojtek
