Rectenly I need to allocate IP to clients via multiple NICs using dnsmasq in my home server.
Originally I just started multiple dnsmasq daemons with different startup switches, for example:
dnsmasq --interface=tap_vpn --except-interface=lo --bind-interfaces --dhcp-range=192.168.250.10,192.168.250.100,12h --conf-file=/dev/null
But I just found out that this can be done pretty simple in the same dnsmasq.conf file.
interface=wlan1 # Use interface wlan0 interface=wlan0 #listen-address=172.24.1.1 # Explicitly specify the address to listen on bind-interfaces # Bind to the interface to make sure we aren't sending things elsewhere server=220.127.116.11 # Forward DNS requests to Google DNS domain-needed # Don't forward short names bogus-priv # Never forward addresses in the non-routed address spaces. dhcp-range=wlan0,172.24.1.50,172.24.1.150,12h # Assign IP addresses between 172.24.1.50 and 172.24.1.150 with a 12 hour lease time dhcp-range=wlan1,172.24.2.50,172.24.2.150,12h # Assign IP addresses between 172.24.1.50 and 172.24.1.150 with a 12 hour lease time
