Description of problem: firewall-cmd --list-all-zones does not show the default ipv6 icmp blocks that are implemented. These blocks can be displayed with ip6tables -L -n Version-Release number of selected component (if applicable): firewalld-0.3.9-14.el7.noarch How reproducible: Build a base RHEL 7.latest Verify firewalld is active # firewall-cmd --list-all-zones | grep icmp icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: icmp-blocks: # ip6tables -L -n | grep icmp ACCEPT icmpv6 ::/0 ::/0 REJECT all ::/0 ::/0 reject-with icmp6-adm-prohibited ACCEPT icmpv6 ::/0 ::/0 REJECT all ::/0 ::/0 reject-with icmp6-adm-prohibited Expected results: I expected to see the icmpv6 rejects in the icmp-block listings for the default zone Additional info: I also have not found how to turn the icmpv6 reject strings off (I will file another bug for that).
This request was very late for 7.3. I am proposing it for 7.4
There is no default reject of ICMP types. The default is to accept all icmp types, which can be limited using icmp-block or icmp-block-inversion. There is no icmp-block by default. The reject line form your "ip6tables -L" output is the final reject line, which is rejecting everything that has not been allowed. But as all ICMP types are accepted before this does not affect ICMP types. Closing as NOT A BUG.
