It looks IPv6 was disabled at this host and adding an allow rule to SELinux would not help to resolve the underlying problem, exposing the denial actually points to the fact there is some problem.

Unfortunately, disabling IPv6 via ipv6.disable=1 doesn't play well with SELinux. Please see bug 641836 for some explanations. It is recommended to disable IPv6 via the net.ipv6.conf.all.disable_ipv6 sysctl instead.

Also refer to the following kbase article:
How do I disable or enable the IPv6 protocol in Red Hat Enterprise Linux?

If there is no other information regarding this issue, we will proceed and close the bz.
