setup ipv6 with BT Infinity(VDSL) through Mikrotik RB750 GR3

Go to solution

Hello

I met a very strange problem about ipv6,I got a Mikrotik RB750 GR3 (ROS 7.2 RC1)router and Huawei HG612 modem, ipv4 part is no problrm. But when I try to setup v6 part,some oddly situation arrived.

 

I add a dhcp-client with 56 prefix

ros_v6_clinet_01.jpg

and status seems ok

 

ros_v6_clinet_02.jpg

and I add address

 

ros_v6_address.jpg

ipv6_rout_list.jpg

everything seems ok, and computer and cell phone shows IP v6 address assigned. the fromat is start with 2a00:23c7:f684

 

BUT

when i go to test-ipv6.com  and ipv6-test.com,include computer and cell phone, got this kind of result

ipv6_result_01.jpg

ipv6_result_02.jpg

 

and also, at win10 ethernet status shows ipv6 "no internet asscess"

When i restart router or modem, the assigned V6 IP of terminal changed synchronous,"pretend" they are really working, but they are not working at all. 

As firewall part, I just turn off the firewall, to avoid any interference。

And i reset router, repeat again, no change.

Changed to BT homehub6A, every problem disappear.

So, could any one give me some suggestion to solve this uncommon miracle?

Thank you very much.

Finally, it solved, after ROS 7.2RC5 updated.

 

And do not select Add default route in DHCP v6 client

After ROS updated.

The related fix log of ROS 7.2RC5 about this ipv6 issue:

ipv6 - do not add duplicate dynamic prefix when static already exists;
