You should think hard and know what you are - doing before using either of these options. The old - default behaviour (use one port allocated by the OS) is available by - setting -query-port=0, and setting the query port to a positive - value is still works. It - now uses a new, randomly selected, port for each query. Second addendum: following the discovery of a security flaw in the - DNS protocol, dnsmasq from version 2.43 has changed behavior. If not - specified, the operating system will select an available port number - just as it did before. Addendum: dnsmasq now has the option 'query-port' (-Q), which allows - you to specify the UDP port to be used for this purpose. The replies must be to oustanding queries - which dnsmasq has forwarded, otherwise they are dropped too. This is not a security hole since dnsmasq will only accept replies to that - port: queries are dropped.

If dnsmasq sent its queries - from port 53 the replies would be _to_ port 53 and get blocked.

The reason for doing this is - that most firewall setups block incoming packets _to_ port 53, in order - to stop DNS queries from the outside world. Queries from dnsmasq to upstream nameservers are sent - from these ports and replies received to them. Is this a security problem/trojan/backdoor? -A: The high ports that dnsmasq opens are for replies from the upstream - nameserver(s). +++ -1,471 +0,0 Why does dnsmasq open UDP ports >1024 as well as port 53.
