A lot depends on your default policies. If you have a default of 
allowing outgoing connections, then the first rule above is 
superfluous as it simply allows something that is already allowed.

However, if you have a default policy to block outgoing connections, 
then that rule is required. You should note that the rule matches the 
DESTINATION port=53 and so is unaffected by whether you use 53 or a 
random source port.
