this works if jabberd listens on the wildcard address or on the primary IP address of the incoming interface.

If it explicitly binds to a secondary address ($XMPPADDR), the DNAT target is needed, because it allows to specify the destination IP address for the redirection:

iptables -t nat -A PREROUTING \
        -d $XMPPADDR -p tcp -m tcp --dport 80 \
        -j DNAT --to-destination $XMPPADDR:5222

Thank you both for the examples . It will make doing the same (here shortly) on my system much more sure of being correct .
