[Dnsmasq-discuss] dnsmasq on multiple subnet help

[Stuart Colk]

Hey all

I have a multiple subnet setup which i am trying to get dnsmasq to control. It works fine when activated on a single subnet, but as soon as i try to expand this i get some very odd errors. Any pointers to a solultion would be greatly appreciated.. conf file below

# Configuration file for dnsmasq
#

dhcp-authoritative
domain-needed
bogus-priv
no-poll
no-resolv
expand-hosts
localise-queries

dns-forward-max=500

# Set a different domain for a particular subnet
domain=live.tv,192.168.0.0/24
domain=render.live.tv,192.168.20.0/24

# DHCP server config
dhcp-range=192.168.0.20,192.168.0.240,24h
dhcp-range=192.168.20.231,192.168.20.250,24h
#dhcp-leasefile=/var/lib/dnsmasq/dnsmasq.leases

# temporary disable eth0 requests
except-interface=eth0
no-dhcp-interface=eth0

# DNS server settings
local=/ldn.unit.tv/
server=8.8.8.8
server=8.8.4.4

# Gateway option
dhcp-option=3,192.168.0.254

# NTP time server setup
dhcp-option=42,0.0.0.0

so i have the render network running fine and dandy, but as soon as i try and add in any other network i get complaints that there are no leases available as per below.
