Hi,

Rabbitmq is starting as an unprivileged user, so it can't bind to ports
less than 1024. I'd suggest using some intermediate layer for that,
maybe haproxy?

Steps:
apt-get install haproxy

Edit /etc/default/haproxy to enable it.
Modify config, to something like

global
        maxconn 2000
        user haproxy
        group haproxy
        daemon

listen  http-server 0.0.0.0:80
        mode    http
        balance roundrobin
        contimeout      5000
        clitimeout      50000
        srvtimeout      50000
        server  inst00 127.0.0.1:8000 check inter 2000 fall 3

Change 8000 to whatever port you need, like 55672.
