IP6tables issue

I have a fully patched centos 7 x64 box which sole purpose is an off-net DNS resolver. we disabled firewalld and installed the iptables-services package.

We have a rule like below for IPv4:

-A INPUT -i enp4s0f0 -m state --state NEW -s [login to view URL] -m tcp -p tcp --dport 22 -j ACCEPT

The IPv4 rule works great.

We originally had the following IPv6 rule:

-A INPUT -i enp4s0f0 -m state --state NEW -s 2620:128:7000::/44 -m tcp -p tcp --dport 22 -j ACCEPT

No IPv6 traffic was allowed to pass at all. So, We altered the rule to:

-A INPUT -i enp4s0f0 -s 2620:128:7000::/44 -p tcp --dport 22 -j ACCEPT

Still, no IPv6 traffic was allowed to pass at all.

I need a freelancer to find out why ip6tables is blocking ALL IPv6 traffic, including traffic allowed by rule. Fix it. Then show and explain to us what was wrong so we can avoid this issue in the future.

We are are hiring at Expert level (50.00/hour). Since we are hiring an expert we are not expecting more than 4 hours.

The rules are shown in the /etc/sysconfig/ip6tables file. Also, 'iptables -L' shows the rules after a service restart.

See the attached file ip6tables_output.txt for the output of the 'sudo ip6tables -L' command.
