Greetings,
I have an issue about set multiple interfaces with different subnet mask.
I set three interfaces, br-lan, br-VLAN4 and br-VLAN5. br-VLAN5 subnet mask
is 255.0.0.0, others are 255.255.255.0
When there is no DHCP leases, DHCP Client can get correct DHCP OFFER from
different interfaces.
But if client get DHCP OFFER from br-VLAN5, and then switch back to br-lan.
It will get incorrect result.
What I expect is it can be obtained in original br-lan dhcp-range. Do I miss
anything?
Here is my dnsmasq.conf and log, you can see last DHCP OFFER from br-lan is
incorrect.

dhcp-range=lan,192.168.10.101,192.168.10.199,255.255.255.0,12h
dhcp-range=VLAN4,192.168.4.101,192.168.4.199,255.255.255.0,12h
In most cases tags need to be set before they can be used. Are the tags
set anywhere else in your configuration?
If no, the following example could help:
dhcp-range=set:<TAG-NAME>,...
