DHCPv6 WAN not working

DHCPv6 WAN not working

Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.6

Here are my WAN settings:

 

 

As you can see I have set "Get IPv6 Address" to "Via DHCPv6", but no DHCPv6 request is made:

 

 

I also tried to set IPv4 to "Static IP" (with some bogus IP like 192.168.99.99 because it didn't allow me to leave it empty) and then entering the PPPoE data specifically for IPv6 but then I have no field for the VLAN ID.

Correct, I mirrored WAN and sniffed the traffic using Wireshark. My screenshot shows everything that goes through the PPPoE connection, if there was DHCPv6 it would show up there. As you can see it does establish the PPPoE connection but it does not send any DHCPv6 request.

 

I made some progress in the meantime by using another router to strip the VLAN tags from the modem connection. Then I was able to set up PPPoE for IPv6 (which doesn't have the VLAN field) and use "Static IP" for IPv4 and now a DHCPv6 request is made. Not ideal, but works for now. These are the new settings:

 

 

 

Well yes, DS-Lite (RFC6333) is just an IPv6-only connection with an IP-in-IPv6 tunnel for IPv4, which is exactly what I'm trying to set up.

Hi @agent_kater 

Thanks for posting in our business forum.

Does your ISP even provide IPv6?

Your Wireshark is done by the mirroring of WAN and you filter with dhcpv6?

Disconnect and reconnect the WAN from the software and physical level, it does not send a single v6 request packet?

 

What's the ISP-provided v6 connection type?

Do they specifically require a mode, e.g. DS-Lite to be able to make a v6 WAN DHCP?

We don't support DS-Lite yet.

That's ok, my question is focused on getting the pure IPv6 working, IPv4 not required at all.

 

Is the DS-Lite support in the latest 5.15 beta by the way?
