Adding min-port to dnsmasq configuration. #9505
Conversation
By default dnsmasq uses lower port (for source port) for it's communications. This sometimes create problem when the forward server is bind or firewalls dropping queries coming from these reserved ports. Upstream dnsmasq defaults setting min-port to 1024, for older versions of dnsmasq setting min-port to 1024 is needed, to avoid random drops. https://bugzilla.redhat.com/show_bug.cgi?id=1600551 https://bugzilla.redhat.com/show_bug.cgi?id=1614331

Yes, if we apply changes to the configuration file, if there are no changes applied it won't restart the service. |

BTW, in older releases we should verify that what I've said about this being applied is true, we simplified all of this in 3.10 or 3.9 so older may require different changes. |
