Description Tomas Dolezal 2016-09-07 15:51:00 UTC 
Description of problem:
enabling masquerading using --add-masquerade and --add-rich-rule 'rule masquerade' leads to different results in both ipv4 and ipv6 netfilter rules.

Version-Release number of selected component (if applicable):
firewalld-0.4.3.2-6.el7.noarch

How reproducible:
always

Steps to Reproduce:
exclusively configure either or:
--add-masquerade
--add-rich-rule 'rule masquerade'

Actual results:
add-masquerade:
==ipv4:
-A POST_public_allow ! -o lo -j MASQUERADE
-A FWDO_public_allow -j ACCEPT
==ipv6:
!nothing

richrule:
==ipv4:
-A POST_public_allow ! -o lo -j MASQUERADE
-A FWDO_public_allow -m conntrack --ctstate NEW -j ACCEPT
==ipv6:
-A POST_public_allow ! -o lo -j MASQUERADE
-A FWDO_public_allow -m conntrack --ctstate NEW -j ACCEPT

Expected results:
both config variants enable masquerading the same way. especially ipv6 rules are either always added or never.
