By default, older versions of dnsmasq can use lower-numbered source ports for outbound DNS queries. This sometimes creates problems; for example, firewall rules may drop queries coming from these reserved ports. To avoid these problems, we can set the minimum port number for outbound queries using dnsmasq's min-port setting. dnsmasq 2.79 defaults min-port to 1024; for older versions of dnsmasq, we must set min-port to 1024.
