[Dnsmasq-discuss] DHCP for multiple address not in the eth0

[Kiswono Prayogo]

hi, i have tried it.. but how do i debug it? what i mean is how can i
know if there are any DHCP request packet sent to my box or from my
box to the client..

***
i run dnsmasq with this command instead of running it as service:

sudo dnsmasq -d --log-dhcp

and got these message:

dnsmasq: started, version 2.47 cachesize 8192
dnsmasq: compile time options: IPv6 GNU-getopt DBus I18N TFTP
dnsmasq: DHCP, IP range 10.10.6.10 -- 10.10.6.254, lease time 12h
dnsmasq: DHCP, IP range 10.10.5.10 -- 10.10.5.254, lease time 12h
dnsmasq: DHCP, IP range 10.10.3.10 -- 10.10.3.254, lease time 12h

dnsmasq: using nameserver 208.67.222.222#53
dnsmasq: read /etc/hosts - 14966 addresses
[no more message, even if the client send DHCP requests]

***
these are my configuration (my box (dhcp, gateway and dns server) ip
address is 192.168.1.254):

dhcp-range=WAP1,10.10.1.10,10.10.1.254,255.255.255.0,12h
dhcp-option=WAP1,3,10.10.1.1
dhcp-range=WAP2,10.10.2.10,10.10.2.254,255.255.255.0,12h
dhcp-option=WAP2,3,10.10.2.1
dhcp-range=WAP3,10.10.3.10,10.10.3.254,255.255.255.0,12h
dhcp-option=WAP3,3,10.10.3.1
dhcp-range=WAP5,10.10.5.10,10.10.5.254,255.255.255.0,12h
dhcp-option=WAP5,3,10.10.5.1
dhcp-range=WAP6,10.10.6.10,10.10.6.254,255.255.255.0,12h
dhcp-option=WAP6,3,10.10.6.1
dhcp-option=6,192.168.1.254

***
the logical topology:

client -- L3switch1 (forwarding bootp/dhcp to 192.168.1.254) -- my box
(192.168.1.254)

L3switch1: set forwarding-options helpers bootp server 192.168.1.254
i.e. if the client got IP 10.10.2.33 then, the gateway is 10.10.2.1,
and the dns server is 192.168.1.254

***
the physical topology:

client -- access point -- L3switch1 -- L3switch2 -- my box
(192.168.1.254) -- internet
