DHCP domain suffix

Hi,

is it possible to append different domain suffixes to (clients/servers) for each DHCP pool with only one dnsmasq instance, if yes, how could I achieve this? or do I need several instances?

Thanks a lot

You should be able to do this by configuring dhcp options per an interface (can be done via Luci). I used this approach to advertise non-default MTU's per an interface.

I think you are looking for option 15 here.

EDIT: Network --> Interfaces --> { IFNAME } -> DHSP Server --> Advanced Settings --> DHCP-Options : add "15,blah" without double qoutes.

@fantom-x, exactly what I was looking for, I can finally overwrite multiple default options! Thank you very much
