How to create a VPN in IPv6 - RB750p

Fri Jul 22, 2016 1:58 am

Hello friends,

I am a layperson on the subject, so I have to learn how to configure a VPN using the IPv6 protocol and then keep the IPv4 protocol for other equipment. This is possible using RB750p? How to configure? Is there any tutorial available?

Thanks!!!

no one will answer you in this forum
Router OS  does not support ipv6 assignment on any VPN protocol
but u can use windows server for this purpose (I have already done this before)
but its not as easy as ipv4
because in ipv4 you just setup pool of private IP (192.168.x.x) and use masquerade rule to NAT them into your public IP
but in ipv6 you need at least /64 public IP pool and they must routed to your  server public ipv6 IP which the clients  can use it as default gateway

sorry for my English  I'm  not  good in English

I have pptp server running on RouterOS providing IPv6 connectivity to its clients. I'm not sure if this is the goal of the OP, or even if this is what you're saying is not possible.

Because each client gets a /64 probably.

yes but it must work with /64 pool because it has /64  free that can complete with EUI64 ( it works in windows server )

Do you mean "it should work"? For one client, yes I agree it should work (one /64 per client). Perhaps it wants a /64 for both ends of the connection (and Windows Server does not).
Why don't you assign it the larger-than-/64 subnet it needs?

I did a test with my server and Windows as a client : it did not assign a subnet from the pool to the pptp server end of the connection (it has a link-local address only).

The big thing here is that Mikrotik's dhcpv6 server only works as a dhcpv6-pd server (not as a stateless server for information options only / not as a stateful server that assigns leases for individual host addresses in a given network). If this has been changed, and ROS is able to do this, then I missed that announcement.

Is it possible to configure the Mikrotik to send RA messages to VPN endpoints so that they can use EUI-64?

when you use /48 pool  in  mikrotik  you assign /64 to your endpoint client
but when you use /64 pool  to provide clients only with a single IP (/128)

There are 3 tunnel types that run over IPv6, see under Interfaces + button.
I regularly use GRE6 and it works OK.
