Sir, I want to disable ipv6 in my FreePBX.
I have checked and tried many commands
but when I restart FreePBX IPv6 appears again.
please tell me which command I need to use.
Add a file in /etc/sysctl.d (assuming that the directory exists), for example 20-disable-ipv6.conf, containing
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
Reboot and test.
I’m new to Linux
please write full command so I can copy and paste from here to disable ipv6
Regards
