With both TCP and UDP, netfilter will use the source port contained in the
original packet if it can (ie: if that source port is not being used for
something else by the netfilter machine). If this is not possible, then
another port is chosen at random using the standard socket-binding mechanism
used for any network connection.

This makes no difference.
