WAP with IPv6

waldes · November 28, 2018, 1:39pm

Hello,

I have two wifi hosts utilizing IPv6 addresses and need to connect them to an AP-Mikrotik mAP 2nd. The first host has a static address and the second is not clear yet (static/dynamic).
Iam unfortunately not familiar with RouterOS and Mikrotik so far, therfore I would like to ask you how to configure the RouterOS.

Thank you.

I have already tried this example but I don’t have LLA on the required interface wlan1 as described in the example: “We also have link local address on the interface which is created automatically for every IPv6 capable interface.” Does it mean that my wlan1 interface as well as both ether1 and ether2 are not IPv6 capable? My host cannot connect.

[admin@MikroTik] > ipv6 address print
Flags: X - disabled, I - invalid, D - dynamic, G - global, L - link-local 
 #    ADDRESS                                     FROM-POOL INTERFACE                               ADVERT

That’s interesting. Seems there are interfaces which not capable to assign LLA. I’ll wait for dev answer

If wlan1 is part of the bridge it will not have a LL address. From the layer 3 (network) point of view, the layer 2 interfaces in a bridge are not even visible, so they should not have addresses. I think you should add the static address to the bridge.

I’ve thought about it, but wlan is interface too and there is no definition of slave port anymore, so.

I tried to add a static global address, see the attached picture. Now I am able to connect my host using IPv6 but in the Wireless Tables/Registration I can always see IPv4 address instead. I can ping IPv4 as well as IPv6. This host is running a TCP server that can be connected with a TCP client unfortunately just via IPv4 and not IPv6. Any suggestions?

Try to ping closest host from server with ICMPv6.

I have already done this (ping the host using IPv6) and it works but I cannot connect to my TCP server running on this host using IPv6 (IPV4 works fine).
