I want to set up dnsmasq to serve DHCP for a subnet to which the router itself is not directly connected to (and so another router will relay the request with option 82 set). Is there any easy way of doing this within the existing set of options available for use in /etc/config/dhcp - or do I just have to edit /etc/dnsmasq.conf?
The main issue seems to be that there's no way of specifying a range outside one that's tied to a specific interface -- and so the subsequent directives also have to go in /etc/dnsmasq.conf
config dhcp lan
option interface lan
option start 1441793
option limit 253
I haven't tried this, but maybe it does work.
But seems quite limited...
Maybe there is some other way to get this working (without using /etc/dnsmasq.conf) ?
