Hi guys,

my dhcp clients get my local dns server with the following commands in the DNSMasq options box:

Code:

dhcp-option= option:dns-server, 192.168.100.200

server = 8.8.8.8
server = 8.8.4.4


I have 4 Networks.
local LAN 19.168.100.0/24
local WLAN/wifi 192.168.24.0/24
guest WLAN/wifi 192.168.50.0/24
vlan4 192.168.10.0/24

All Networks have their own dhcp scopes.
But with these commands in the DNSMasq options box all Networks get my local DNS-Server 192.168.100.200.

I want deploy the local dns server for local lan+ local wlan/wifi only, not for the guest wlan/wifi and not for vlan4. They should use the google dns Server for internet access only.

Any help is appreciated

Thank you!

you can define DNS Server for each interface, e.g.:

dhcp-option=br0,6,x.x.x.x.,y.y.y.y
dhcp-option=vlan4,6,x.x.x.x.,y.y.y.y
dhcp-option=wl0,6,x.x.x.x.,y.y.y.y
dhcp-option=wl0.1,6,x.x.x.x.,y.y.y.y
