ISP IPv6 only issue

Post by nevets »

It seems that I can no longer get Ghost to connect to the internet at all since the network of my ISP went to IPv6 only.
The network is unreachable.
My old gateway/modem won't connect at all.
The new modem/gateway works in Devuan, but not FreeBSD/Ghost
I noticed in Devuan that apps [linphone] where I can turn off IPv6 fail to reach the internet if I do so.
Are there any specific FreeBSD setup requirements to handle the IPv4-IPv6 translation from the pc to the router/gateway?
Everything was sweet until the wireless network was upgraded.
rc.conf and sysctl.conf have the default setups from a fresh install.

Welcome to GhostBSD!

try adding this to /etc/rc.conf

ipv6_enable="YES"

No joy,
ipv6_enable is deprecated.
used
ipv6_activate_all_interfaces="YES"
instead... still no joy.
The kernal runs ipfw2 (+ipv6) if that's important.

ifconfig_em0_ipv6="inet6 accept_rtadv" in /etc/rc.conf

Change em0 in this line if necessary for your network card

Still not working...
Thanks for the assist Neville, but I think something else is the problem now.
I tried to install Debian11 from netinstall and it failed to connect.
I installed Debain from a full iso and the installed system couldn't connect either.
Yet this old Devuan (Debian with openRC from May) is partially working for me to write this post.
I even tried Tails too and that couldn't connect.
Chasing my ISP now ... the internet behaves as if I don't have GB credit

Summary
Old modem/Gateway WLAN [TL-MR6400 v3] just suddenly couldn't connect to internet.
New modem/gateway [TL-MR6400 v5] does connect to internet.
FreeBSD and new Linux OS's can't get a return from the internet.
Same issues with a different PC box and hardware.
An old Devuan works apart from IPv4 specific connections like my VPN

@nevets would you make a ticket to add ipv6 support for GhostBSD?

I've raised the ticket Eric.
As an interim solution I changed ISP and now get served an ipv4 address....
