[Dnsmasq-discuss] multiple subnets behind DHCP relay

[Takács Balázs]

Dear all,

I have a setup where there are two (or more) separate subnets behind a DHCP relay. 

                 DHCP relay
               |------------|           |-------------|
    10.1.0.1/16|eth1        |10.0.0.0/16|Dnsmasq sever|
 --------------|        eth2|-----------|             |
   195.x.x.1/24|eth1.1      |           |             |
               |------------|           |-------------|


  The relay sends all the request from 10.1.0.1 IP address. The default subnet for clients is the 10.1.0.0. This works ok.
  Based on client mac address I would like to place some clients in 195.x.x.0/24 (public ip)subnet.
I have set both the pools for 10.1.0.0 and 195.x.x.0 subnets in dnsmasq.conf and placed mac address ip address pairs to /etc/ethers file for clients have to get public address. But the specified clients still get ip from 10.1.0.0 pool. Is there a possibility to force dnsmasq to ignore the DHCP relay address and try to give out address even in case of subnet missmatch?

Thank you in advance,

T.
