received.<br></p><p>And of course, this issue has to do with docker. With Docker, even
though the container is listening on 2 different interfaces, and 2
different IPs, the inner container, and thus dnsmasq, only sees 1
interface, with all addresses coming from it. Hence localisation isn't
quite working.<br></p><div>If I run dnsmasq with the exact same config but on the host, where it can see the different interfaces, works perfectly!<br></div><p>Testing was done in 2.79 and 2.76, with a config file practically identical to your CLI arguments.<br></p><p>Technically, there's not a bug here per-say, but it'd be really handy
if there was a way of looking at the source IP when determining which
record to return rather than just the interface?<br></p><p>Thanks!<br></p><div>On Mon, 30 Mar 2020, at 20:42, Simon Kelley wrote:<br></div><blockquote type="cite" id="qt"><div>On 28/03/2020 20:38, Jake Howard wrote:<br></div><div>> Hi,<br></div><div>> <br></div><div>> My intention is to have 1 dnsmasq instance, accessible over 2 interfaces<br></div><div>> (listening on all), and have the response to a query differ based on the<br></div><div>> interface, and therefore its incoming IP.
