How do I disable Shorewall, IPtables?

You may follow these procedures to disable shorewall on your head node.

First, run the following commands on your head node to prevent Bright from automatically restarting shorewall:

# cmsh
% device use master
% services
% set shorewall autostart no
% set shorewall6 autostart no
% commit

Next, stop and disable both shorewall services:

# systemctl stop shorewall
# chkconfig shorewall off
# systemctl stop shorewall6
# chkconfig shorewall off

Then, flush the iptables rules:

# iptables -F INPUT
# iptables -F FORWARD
# iptables -F OUTPUT

After that, you would set the default policy on each table to be ACCEPT:

# iptables -P INPUT ACCEPT
# iptables -P FORWARD ACCEPT
# iptables -P OUTPUT ACCEPT

Please note that performing these actions should not interfere with Bright’s management of your cluster.
