So,

after I do a fresh installation, it works fine (after restore my config).
But when I recover all plugins, it stops working after a reboot. So I think, a plugin will break prefix delegation?

Hi,

I will test it.
But I think, dhcp6c doesn´t start, because it didn´t get an prefix?

On WAN it gets an ipv6 adress from fritzbox, but it didn´t get an prefix delegated?!

When I check
sudo ps uxawww | grep dhcp6c

there is no dhcp6c process running?!
How can I start it??

WAN get´s its ipv6 but no prefix and delegate!
I restart OPNSense and also push Reload on Interface-Overview-WAN Interface. No change.

Hey,

Does it work for the rest of you?
I have my OPNSense behind the Fritzbox.
It is connected as an exposed host.
 
In the FritzBox I have -Assign DNS server, prefix (IA_PD) and IPv6 address (IA_NA)- and -Also allow IPv6 prefixes that other IPv6 routers in the home network b- activated.
My ISP send the FritzBox /56 networks for delegation.
In OPNSense I set delegation size to /60.

This works in the old OPNSense version.
At the new versions, I don't get any networks for delegation from the Fritzbox.

I tried different things:
-Request Prefix Hint only ON/OFF, etc.
Are there any logs I could include here?

Need help please

Greets

What could the problem?
Running under 24.7.5_3 but above not?
When I restore Backup from this version in Proxmox it runs well immediately.

Same config, starting update, then it doesnt work anymore!
Restore Backup from 30 minutes ago, old version, runs well and gets ipv6 pd fast.

@troplin:
Did you get an ipv6 prefix? Wich size?
Mine is 60
(because FritzBox get its own networks for guest automatic).

Hi,

I run the OPNSense behind a FritzBox.
The FritzBox delegates ipv6 to OPNSense.
This worked wonderfully up until version 24.7.5_3.

Since then (24.7.11_2) the FritzBox stopped delegating ipv6-networks to the OPNSense!
However, the WAN connection receives an ipv6 address from the FB network.

So after Verson 24.7.5_3 ipv6-Delegation is broken!
So I stuck on Version 24.7.5_3!!

Hi,

I´ve got an issue on OPNSense start, my LAN Interface doesn´t get an ipv6 (track interface) from WAN interface.
But if I klick reload on Interfaces->Overview at the WAN interface, it gets a new ipv6.

So how can I perform this click over ssh?
Wich scripts can I start?

/usr/local/sbin/configctl interface linkup stop <interface> && /usr/local/sbin/configctl interface reconfigure <interface> && /usr/local/sbin/configctl interface linkup start <interface>

doesn´t work.

Greets

Hi,

the error still exists!
I get no ipv6 over delegation from my fritzbox!
Whe I downgrade, it works fine!

@franco: Is there a chance that the error will be repaired soon?
My last working OPNSense ist V 24.7.5_3


Greets

Hi,

is the prefix delegatoin issue fixed on 24.7.7?
Has someone test it?

Greets

Sorry,

I think its the update problem.

I updated from 24.7.4_1 to 24.7.6!
This causes the problem back.
Its a bug, look here

https://forum.opnsense.org/index.php?topic=42556.0

Same to me.

I ve updatet opnsense from 24.7.4_1 to 24.7.6.
Now Im getting the problem no ipv6 Prefix.
It took me hours, now I see this post.

I will try to get to 24.7.4 back or is there a bugfix??

Hi,

it worked well the whole time.
All of a sudden I don't get an ipv6 subnet assigned, even though my Fritzbox has been given a network to delegate from my ISP.

IPv6-Adresse: 2a00:XXXX:XXXX:XX::XXXX/64, Gültigkeit: 3433/3433s
IPv6-Präfix: 2a00:XXXX:XXXX:XXXX::/56, Gültigkeit: 3433/3433s

Restarted FritzBox and OPNSense serveral times.

Greets

Thanks, I will try it.

'Thanks, I´ve seen this, but which parameters should I use?


/usr/local/opnsense/scripts/Wireguard/wg-service-control.php restart wg2  ?


What is   uuid or vhid is this the interface name??
