Dns server in another interface

lou

Hi, I have two interfaces. LAN1 and LAN2. In lan1 i have DNS server. I would like configure LAN1 DNS SERVER for LAN2.

I created a rule that allow traffic between LAN1 to lan2. But it can't work.

any idea that i do wrong?

Thanks

Which interface did you put the rule/s on?
To allow access from LAN2 into LAN1 you need pass rule/s on the LAN2 tab, source LAN2 subnet addresses, destination LAN1 subnet addresses.

Hi!

Yes i did that.

Lan1 subnet: 192.168.150.0 /23
Lan2 subnet; 172.16.1.0:/24

DNS server: 192.168.150.1

I don't know how I do to configure it

Thanks!

On LAN2 you need a rule:
pass all source LAN2net destination 192.168.150.1
Post your rules if you are stuck.

If you want to allow only dns, then your rule would be as above with tcp/udp 53 as the dest port.

But why not just allow dns queries to the lan2 interface IP? This would be a more common setup - dnsmasq can run on whatever IPs you want it to listen on.. Not like you have to run another instance of it or anything - it will just listen on more than one interface is all for queries.
