How to configure PPPOE IPV6 Server with External Radius

Debasish · March 13, 2019, 6:02am

Dear Team,

I’m trying to configure PPPOE server with IPV6 address.In this scenario we have configured Mikrotik as NAS with another Radius server and Radius will throw the IPV6 address to the client through Mikrotik PPPOE server. So , I have configured IPV6 address,ND,Pools,Neighbors, settings in mirkrotik and also configured PPPOE server.
The problem is that end pc is getting Link local IPV6 address only instead of configured pool ip.
Please see the mikrotik LOG details:

19:53:21 radius,debug received reply for 1b:00

From the above log you can see that Radius was forwarding IPV6 address " 2002:1:0:1::/64 " and I also received prefixes in " Neighbor Discovery — Prefixes" on logged in pppoe user but its not working and END PC is not receiving any ip address of the pool " 2002:1:0:1::/64 " and showing Link local address only.

Please suggest me if anyone have any information about Mikrotik PPPOE IPV6 Server.

Thanks and Regard,

Mikrotik IPV6 Problem Note:

1.Can’t forward IPV6 DNS address to the pppoe client .
2.can’t see limit input and output data in pppoe user.
3.PPPOE client full IPV6 address is not showing only showing prefix.
4.after configuring tunnel through tunnelbroker.net we can ping to outside through IPV6 address but we can’t able to surfe or open the page.

I have tested the IPV6 in Mikrotik with Radius,Please see the below testing result :-

Working functions with IPv6 In Mikrotik:
(a) DHCP and PPPOE IP leasing is working and for PPPOE our PC was able to get EUI-64 address but always need to put manual IPV6 DNS address at this
type and we are looking for the solution for that.
(b) Sometimes internet is working through tunnelbroker.net/tunnel but most of the cases facing DNS issues.
Not-Working functions with IPv6 In Mikrotik:

(a)We have tested the network with dual-stacking and only on IPV6 also. In Dual-stacking, we have to use both IPV4 and IPV6 and most of the cases
traffic was forwarded by IPV4 not IPV6. In only IPV6,we are able to ping any IPV6 address but can’t open the website and we found that the issues is for DNS.
(b)User IPV6 address: we are unable to see the client IPV6 address ,only able to see the prefix address like 2001:470:19:16d0::/64 instead of
2001:470:19:16d0:fedo:fe50:1151:10:/64 which is actually EUI-64 address.
(c)User management: In Mikrotik here is no visibility to monitor or manage the client over IPV6 address wheather it’s PPPOE or IPOE.
(d) Client accounting: We also unable to see the usage in Mikrotik on IPV6 address and also unable to send the accounting details to radius solution 24online.
