Help with IPv6

[djGrrr]

You will want to run this command from ssh:
clog -f /var/log/dhcpd.log

and watch it while applying interface settings on WAN; you should see log entries from dhcp6c.

Nope, still nothing, just entries from "dhcpd"

I'm now on 17.1.5 and I wanted to revisit this issue.

I still get an IPv6 address to my WAN (VLAN PPPoE, request IPv6 via IPv4), but none of my LAN interfaces get an address. I've stuck to keeping it simple on the WAN, and chosen "Track Interface" on each LAN network giving them different Prefix IDs.

Any ideas?

Hi,

what is your config on the WAN interface for "DHCPv6 client configuration". Which configuration mode are you using? If it is "Advanced" then please switch to "Basic". I had used "Advanced" for the "debug"  switch but it stopped it from working. I switched to "Basic", waited some time and then I had IPv6 running on the LAN interface and the clients behind.

Best regards,

    Jochen

Already on "Basic"

Please enable

- Request only a IPv6 prefix
- Directly send SOLICIT

Do you get a /56 from your provider?

Either option causes the WAN to lose the IPv6 address from my ISP

Do you get a /56 from your provider?

That's what I have been told by my provider, but I don't know how to prove this.

I don't have an IP on the WAN  either ... that IP moves to the LAN and then the DHCPd is able to send IPs to the systems in your LAN ... but you should be able to connect to IPv6 systems from the Firewall still ...

Correction: I have an IP on the WAN but only in the output of ifconfig ... the GUI only shows the fe80 address.

Tried it again, left it a while, still no IPv6 addresses get assigned to either of my LANs - nothing shows on the dashboard nor on the interface overview page.

Log onto the system via ssh and run as root:

Code: [Select]

clog -f /var/log/dhcpd.log
And then press the Save button on the WAN interface again and report what lines got added to that file.

No problem, but thanks for the help - it always helps to try things out in case I missed something before.


Hopefully someone else can help soon.
