[Dnsmasq-discuss] DHCP always listeing on 0.0.0.0:67

[Joachim Lindenberg]

Hello,

I am new on that list and may not have seen previous discussions on this, any pointer appreciated.

I tried to restrict dnsmasc to specific IP addresses, using --listen-address (actually the OpenWrt variant). I figured out, that this causes DNS listening addresses to be specific, but not DHCP. DHCP always uses  0.0.0.0:67. Is there any means to restrict DHCP listening as well? My goal is to allow a DHCP relay to listen on same port but a distinct IP on the same interface.

Actually https://thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html doesn´t tell that --listen-address is specific to DNS. Thus it is unclear to me, whether this is a specification or implementation error or whatever.

Thanks,
Joachim
