I'm sure I saw this work a few weeks ago, but currently I'm unable to contact rabbitmq from guest VMs.
On cloudcontrols we have these firewall rules:
ACCEPT tcp -- 172.16.0.0/21 anywhere tcp dpt:amqp ACCEPT tcp -- 172.16.128.0/24 anywhere tcp dpt:amqp ACCEPT tcp -- 188.8.131.52/25 anywhere tcp dpt:amqp ACCEPT tcp -- 184.108.40.206/29 anywhere tcp dpt:amqp
But on a Trove guest (172.16.128.233) I'm unable to reach rabbitmq.
root@trove3:~# telnet cloudcontrol2001-dev.wikimedia.org 5672 Trying 220.127.116.11...
Is there a filtering rule blocking this? Or am I just making a mistake with my firewall math?
