IPv6 DHCP delegated prefix issue

RE: IPv6 DHCP delegated prefix issue

I tried to get the pppoe client running on my Draytek 130 but then it's automatically NATting and not possible anymore to get the public IP addresses at the LAN side. So I'm out of options and have to wait till the bug is fixed...

thats what i wrote on astaro.org, thats what i wrote back to the engineer. Bottom line is that 99% of their customers probably dont need it so its not very high on their agenda.

Fun fact 1: its not working on their "next gen firewall" either
Fun fact 2: free open source router firmwares like openwrt support it, lancom supports it, AVM fritzbox supports it. Few thousand euro appliance = nah.

Thanks for your reply. It's realy not of this time anymore that IPv6 is not properly supported and that the bug will not be fixed. Thanks Sophos :-(

it doesn't work, i spoke with a sophos quality engineer a while back. its not on their agenda to fix ipv6 over pppoe on the short run.

Hi Scott,

Why the silence? Is the output as expected or not?
Thanks in advance for your reply.

Regards,

Ed.

I was close. I typed CC instead of cc.
The output is: 0 'REF_DhcStaLan' [on LAN]

Enable and configure Shell access in WebAdmin at Management > System Settings > Shell Access.
Connect via SSH to the UTM. Must use Putty, but there are many other programs that can be used.
Login as loginuser
Once logged in, type "su -", without the quotes, then hit enter to elevate to root. Use the root password you set, when prompted.

Now you are root. Each of the following lines is a command, so hit enter after entering each each:
CC
ipv6
prefixes@

When done, the command is Exit to leave CC and go back to the Bash prompt.

Be aware that changes made from the backend are unsupported. If you have a paid licence, making backend changes does void your support. With the above commands, we are just information gathering (seeing if it shows the old or new prefix) and not changing anything, so you're safe. :)

Oops, now you got me. I'm not a Linux expert. Can you please explain how to enter these commands?
Thanks.

Try in Confd. From shell, as root:
CC
ipv6
prefixes@

to see what's in there now.

Too bad. But there must be another file where the old prefix is in. If I find this and change the prefix into the new one, who knows. Otherwise hoping that Sophos will fix this. In any case, thanks for your help.

not that i know of without sophos fixing it. I even talked to two QA Engineer and had him on my UTM but than didnt hear from him again other than that i would need to open a ticket for it (which i did through a partner)
All of this was several month ago.

So there is no way to get this working again?

RE: IPv6 DHCP delegated prefix issue

Ed R — Wed, 11 Nov 2015 14:51:02 GMT

There was 1 file with the .leases extension. I opened it and the old prefix was in. Then I did serveral things:
1. I renamed the file and run the script. That didn't help
2. I rebooted the computer. That didn't help
3. I renamed the file back to the original name and put the new prefix in place and then rerun the script. That didn't help. I still get the old prefix at the IPv6 Global page. So it should be stored elsewhere.
Below you will find the IPv6 log from the moment I put the switch IPv6 to ON till the moment I switched it OFF again. Remarkable are the lines with eth1 in it. As eth1 is the LAN adapter and eth0 is the WAN adapter. I hope this does ring a bell

IPv6 Prefix Delegation over PPPoE is - Broken - i have reported this several times and commented on that on the old Forum. Its not on Sophos Priority List.

RE: IPv6 DHCP delegated prefix issue

scorpionking — Wed, 11 Nov 2015 11:07:06 GMT

Try as root:

rm /var/chroot-dhcpc/var/db/*.leases6

/var/mdw/scripts/ipv6_watchdog restart

Does that help?

Otherwise please post relevant log line from IPv6 log.
