Hello,
I have an ISP with PPPOE connection that requires VLAN-tagging.
Currently I have following configuration:
1) VLAN interface connected to igb0
2) PtP interface connected to VLAN
3) WAN interface assigned to PtP
This works perfectly fine and WAN interface gets IPv4 address properly, but IPv6 is link-local (fe80::/7).
ISP claims they are assigning IPv6 range... In the log of the PtP interface I could find this:
2023-07-25T12:08:34 Informational ppp [wan] IFACE: Rename interface ng0 to pppoe1

2023-07-25T12:08:34 Informational ppp [wan] IPADDR 0.0.0.0
Those IPv6 ranges (if they are /64 ranges) look very strange for me. Can you guys suggest whether I am doing something wrong or do I have to keep pushing the ISP?
How did you configure the DHCPv6 client?
Problem solved. After 2 hours on the phone with the ISP they figured out to tell me that 1) I needed to do DHCPv6 over IPv4 connection, 2) set VLAN Priority to 7 (!)
