DNSMASQ Send Different DHCP Options by Hosts

I choose DNSMASQ as DHCP server, and I want to push different ‘router’ setting to clients.

DNSMASQ supports tagging on hosts/ip ranges/subnets, I tag my mac address (with static ip-mac binding) as ‘prx’ and set ‘option:router’ to 192.168.1.20 if tag matches ‘prx’.

Here is my configuration:

# default dhcp range
dhcp-range=192.168.1.100,192.168.1.199,12h

# default router and dns-server options
dhcp-option=option:router,192.168.1.1
dhcp-option=6,192.168.1.1

# bind 00:11:22:33:44:55 to 192.168.1.50, named as 'sskaje', tagged as 'prx'
dhcp-host=00:11:22:33:44:55,192.168.1.50,sskaje,set:prx

# sed hosts tagged as 'prx' default router to 192.168.1.20
dhcp-option=tag:prx,option:router,192.168.1.20

# default dhcp range

dhcp-range=192.168.1.100,192.168.1.199,12h

# default router and dns-server options

dhcp-option=option:router,192.168.1.1

dhcp-option=6,192.168.1.1

# bind 00:11:22:33:44:55 to 192.168.1.50, named as 'sskaje', tagged as 'prx'

dhcp-host=00:11:22:33:44:55,192.168.1.50,sskaje,set:prx

# sed hosts tagged as 'prx' default router to 192.168.1.20

dhcp-option=tag:prx,option:router,192.168.1.20
