IPv6 not fully working behind station pseudobridge clone

RouterOS General
1

Hello,
I have RB411 (RB-client) wirelessly connected to another RB, RB-client’s mode is station pseudobridge clone.
Home LAN is connected via bridge (bridging wlan1 and ether1 on RB-client).
RouterOS version is 4.5 on both devices.
IPv4 works fine everywhere on LAN, but IPv6 works only on one computer at once. I can see right v6 address on all pc’s, which computer gets via
neigbour discovery messsages comming from gateway. But v6 works only on first computer, which starts first communication after RB-client reboot.

Situation scheme:

gateway router ( linux PC, running ospfv3, sends ND)
 ||
RB-AP (mode ap bridge)
 ...
 (wireless)
 ...
RB-client (mode station pseudobridge clone)
 ||
LAN

As you can read at : http://wiki.mikrotik.com/wiki/Manual:Interface/Wireless
" In pseudobridge mode there is single entry in address translation table for all non-IP packets, hence more than one host in the bridged network cannot reliably use non-IP protocols. "

Is this the reason, why ipv6 works only on one device in my LAN at once ?
Or there is possibility to set something else on RB-client to get v6 fully working in my LAN.

If this is that reason, could I ask developers to improve ipv6 support in mode pseudobridge clone ? :slight_smile:

Thanks for any suggestions.

Currently IPv6 does not work with pseudobridge (it should not work with other similar pseudobridge implementation on other vendor devices too).
Alternative solution should be used (for example WDS), if you need to get IPv6 working.

If WDS is not an option and still need to get IPv6 working?

Or what about new version of RouterOS? Will be improve in this way?

Thanks, confirmed, ipv6 works good in wds station mode. But is that optimal configuration for ipv6 clients ?

It is known that pseudobridge has the limitations. Currently it is not possible to use IPv6 over pseudobridge.

Yes, I know it yet. I have experimentally verified this :sunglasses:

But the question now is: can we expect some better ipv6 support for any other kind of client mode ?
WDS mode has higher overhead then pseudobridge client, I guess, and it is a little bit pity to use it for client connection.

IPV6 is coming and you can be the (possibly) first vendor, who will release some better pseudobridge implementation supporting ipv6 (or something simillar mode), that would be a good advertisement for you, wouldn’t be ? :smiley:

Which overhead do you mean?

psuedobridge wont work because its does MAC translation, and for IPv6 to work you really need the end users to have unique MACs. You should just use a routed setup without WDS or bridging at all and it will be fine, with no overhead at all.

There is such legend like here.
