[Dnsmasq-discuss] Serving Addresses on Multiple Subnets

[John Stowers]

Hi All,

I have read quite a bit of old postings on this, and have not been able to
make this work. Some help would be appreciated.

Our lab does multiple camera tracking using ethernet camers. Each computer
has 4-8 cameras connected (via a POE switch) to
a camera.

Currently I manually assign to a private subnet, one camera and one port of
each card.

I would like to move to a system where I can assign these cameras via DHCP.

This is the current setup.

I have a debian machine running dnsmasq acting as a gateway.
eth0 connects to the internet
eth1 connects to the local 192.168.1.X network

On the local network are the tracking machines; many machines with the
following configuration
eth0 gets 192.168.1.X
eth1 192.168.21.1
eth2 192.168.22.1
eth3 192.168.23.1

etc. and cameras

192.168.21.2
192.168.22.2
192.168.23.2

etc.

I cannot seem to configure dnsmasq to hand out addresses on anything other
than 192.168.1.X. Here is the relevant parts of the dnsmasq configuration.
Can anyone help?

#(192.168.88.X is like the 192.168.2X.X ones above)

#this line works as expected,
dhcp-range=interface:eth1,set:lan,192.168.1.100,192.168.1.255,255.255.255.0,2h

#if only this line is present then the 88.1 address never gets handed out
#no address range available for DHCP request via eth1
dhcp-range=interface:eth1,set:lan,192.168.88.1,static

dhcp-host=00:1e:8c:3d:ae:a6,set:lan,192.168.88.1

Regards,

John
