The External Feeds panel is useful when you use an external service such as Feedburner to manage your RSS feeds.
In this case, enter the URL(s) of your RSS2 and/or Atom feed in the appropriate field(s).
On subsequent accesses to your RSS2/Atom feeds, your readers will be automatically redirected to the aforementioned URLs.
the URL you would give to Feedburner as a source would be:
(just add &redir=no at the end of the URL).
b2evolution is set by default to avoid redirects to external domains, in this case you also need to modify that setting by going to the file _advanced.php and changing the value of the variable
$allow_redirects_to_different_domain to always.
