Description Dean Peterson 2016-02-22 23:10:14 EST
Description of problem:
I performed an ansible install of openshift origin.  If I am on the local machine, I can bring up openshift in the browser.  However, on any external machine, I am no longer able to access anything on the openshift master.  I am unable to ssh, or visit the openshift web console in a browser.  I checked iptables and all of the necessary ports are open.  I even stopped it.  Firewalld is also not running.  I was able to ssh prior to the ansible install but something during that install blocked all external traffic.  How do I open things back up?  When I uninstall openshift using the same playbook the network is restored.

the ansible scripts should have configured firewalld or iptables-services with additional information, but should not have broken things like ssh which were previously correctly configured. Can you show us your iptables rules not?

iptables -nvL
iptables -nvL -t nat

systemctl status iptables
systemctl status firewalld

cat /etc/sysconfig/iptables

Thank you!

closing bz as this was filed twice. Either forum is ok, but both is inappropriate.
