Block IPV6 ~ ClearOS, for good!

Good day!

I have detected on my pfsense connected under ClearOS setup @
,,…. 😉 generating IPV6 traffic,…,

,,… here is the way to block all IPV6 in ClearOS!

Disabling the ipv6 module by adding or changing the following file on your ClearOS !

# nano /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 =1

for sure you already block IPV6 in
# nano /etc/modprobe.d/disable-ipv6.conf

options ipv6 disable=1
