Nice find on not so nice packet conversion: [WayBack] Fun with IPv6 We were investigating packet loss. The loss rate was very low (smaller than 1 of 1000) but as UDP was used, it caused rare but noticeab… – Martin Seeger – Google+
Basically the load balancer could not cope well converting empty IPv4 UDP checksums to IPv6 and back.
Or like Kris mentioned it: [WayBack] Null. In Zahlen: -1., causing a nice set of comments to be posted on short term solutions versus long time forgotten problems.

Mikrotik has great hardware, great firmware (if you have the right builds), but notoriously bad documentation and a not so great software release and testing process.

I both understand the [WayBack] Urgent security advisory – MikroTik and the users reluctant to upgrade: Mikrotik has a history of updates breaking existing behaviour and underdocumenting features and release notes.
The attack is over the www or www-ssl services which by default run on port 80 and 443. You can see on which networks they are bound using this example from the terminal:

Mikrotik and SFP versus SFTP+ is always confusing especially as the text on their equipment and their documentation doesn’t show well which situations work.
Equipment text is further on, this is their text searchable documentation:
As usually, a long search in the forums reveals the background information:
[WayBack] SFP in SFP+ slot – MikroTik RouterOS: 10Gb SFP+ sockets are usually backward compatible with SFP, but this is not guaranteed.
There are two tricks involved to get an SFP connection between these devices working:
