IPv6 can't get it enabled (firewall issue)

FreePBX Networking

Due to the fact that IPv6 is not enabled on my home freebpx instance, I encounter Firewall issues. So I tried to enable IPv6 as suggested here, but I must forget some steps:

/etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=“$(sed ‘s, release .*$,g’ /etc/system-release)”
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT=“gfxterm”
GRUB_CMDLINE_LINUX=“crashkernel=auto rd.lvm.lv=SangomaVG/root rd.lvm.lv=SangomaVG/swaplv1 biosdevname=0 net.ifnames=0 rhgb quiet”
GRUB_DISABLE_RECOVERY=“true”
GRUB_BACKGROUND=/boot/splash.png

and rebuild afterwards via grub2-mkconfig

service network restart or reboot does not provide a IPv6 address when checking with ifconfig

/etc/sysconfig/network-scripts/ifcfg-eth0

Removed all IPv6_Disabled=1 lines in the config (I think), but still no IPv6…

Any help is welcome

FreePBX Distro supports IPv6 at the OS level without any modification.

This seems likely to be a network issue. How are you providing IPv6? If you are using SLAAC it will “just work.” If you are using DHCPv6 you will need to enable that with IPV6_AUTOCONF=no (disable SLAAC) and DHCPV6C=yes (use DHCPv6).

I only have an IPv4 network up and running. Have a DNS server for DHCPv6. In my opinion I should have a private IPv6 address assigned to this instance, but I don’t see it
