of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even
to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.” - Carl Sagan</span></div>

<div class="PlainText">Hi,<br>
<br>
I am running dnsmasq 2.86 on openwrt, and have multiple vlans in my <br>
network. dnsmasq works great for dhcp purposes (for both dynamic and <br>
static leases) that I need for all interfaces/vlans. However, some of <br>
the vlans I do not need/want to have dnsmasq providing dns, but another <br>
dns server for content filtering purposes.<br>
<br>
I'd prefer to keep both dns servers on the same host/router, but the way <br>
dnsmasq works, either binding to interfaces, or wildcard, binds to all <br>
port 53, so that the 2nd dns server can't bind.<br>
<br>
It appears that when dnsmasq is set to bind to interfaces, it has to <br>
either offer both dns and dhcp, or skip dhcp by "--no-dhcp-interface" <br>
argument, but there is no counterpart "--no-dns-interface".<br>
<br>
Setting port=0 disables dns service on all interfaces, which is not what <br>
I wanted as well.<br>
<br>
I did found there were two discussions regarding this:<br>

<br>
Running two instances of dnsmasq doesn't resolve this issue, since I <br>
still rely on dnsmasq's dhcp.<br>
<br>
<br>
Thanks.<br>
