Thanks for this precise answer.

So the only thing I have to do is to use DNS SRV. Good news.

Does this need any special configuration in the jabber.xml file or is it
jabber default behaviour to use such records ?

Yup. There has to be _some_ default port that all jabber servers listen on.
is pretty standard..SMTP does the same thing. 

If you wanted to have your jabber server listen on another port, you can use
DNS SRV records (versus the standard A record) so that other servers get the
port you are listening on when they do the DNS query. If you don't have a
record setup for your server, other servers will be default just use TCP
port 5269.
