PPPoE: Static IPv6 assigned to wrong interface

[falcon1]

Hi there,

I am looking for some ideas as I ran out of them. Hopefully someone around here can help me. I have a dual-stack DSL config with a static IPv4 address and a static IPv6 48-bit prefix. No DHCP or similar on the WAN side.

My modem is connected to igb3, so I defined a Point-to-Point interface pppoe0 on that port.
I also created an assignment from pppoe0 to an interface I called "INTERNET". The IPv4 configuration type of "INTERNET" is set to "PPPoE" and works without trouble. I set the IPv6 configuration type to "Static IPv6" and defined my address to be "2a01:1720:abcd::1/48".

Watching via SSH I expected to see "2a01:1720:abcd::1" appearing on interface pppoe0. But instead it was assigned to igb3:

igb3: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ...
        inet6 2a01:1720:abcd::1 prefixlen 48
        ...

This is completely wrong as the IPv6 address needs to be assigned to pppoe0 instead of igb3. I cannot see any mistakes in the configuration steps I took so this might well be a bug. Any ideas?

Best regards,

Steven

Check  the Use IPv4 Connectivity box in the DHCPv6 client configuration section, see if that fixes it.

It should. As the OP describes it it works as configured: option off, VIP not on pppoe device.

I will try that out as soon as I get back home.

Are you sure about that DHCPv6 setting? I have to use static addressing for IPv6, no DHCPv6...

[franco]

It's available for static as well and if you checked you would see that's true.


Cheers,

Yes, sorry... should have pointed that out as he's using static. Either way, tick that box.

Thanks. That worked!
