I’ve been pretty negative recently in my posts here (I would argue justifiably, though that’s neither here nor there at the moment), but I want to take a moment to offer well deserved praise and give credit where credit is due.  So: THANK YOU MikroTik (genuinely) for FINALLY getting around to implementing IPv6 Fastpath/Fasttrack support.  The lack of this has been a HUGE showstopper in doing a major IPv6 push to most of our end-users, since we have deployed a LOT of RouterBOARDs to customers as CPE.  And prior to this, IPv6 forwarding performance was notably worse than IPv4 (which has had FP/FT for forever now). However… My experience has been largely the same as most others here with 7.18(.2), which is that I can get IPv6 Fast TRACK to work great, but Fast PATH does not seem to work. Now, perhaps this is completely a cosmetic/reporting bug, and IPv6 Fastpath actually works just fine; I have not yet taken time to measure actual performance to see if that is the case.  But, if I have IPv6 connection tracking turned off, zero IPv6 filter/NAT/mangle rules defined, and ‘/ipv6/settings/allow-fast-path=yes’, then it will show ‘ipv6-fast-path-active: yes’, BUT the ‘ipv6-fast-path-packets’ and ‘ipv6-fast-path-bytes’ counters do NOT budge from 0 at all . If this is just a cosmetic bug, it’s very different from the one afflicting IPv4 FP/FT in 7.18, where Fasttrack works and the counters count up, but it says ‘ipv4-fasttrack-packets: NO’.  I understand this reporting error is fixed in 7.19beta. I haven’t been super bothered by (apparent) lack of working IPv6 Fastpath in 7.18.x, since we are largely deploying this on customer CPE where it’s pretty important to have some common-sense firewall rules in place, so IPv6 connection tracking has to be on, and thus we take advantage of Fasttrack instead, which seems to work fine.  But since Fastpath is supposed to be a headlining feature, and since it would be nice to see this working properly on, say, CCR hardware that’s sitting on our network and forwarding IPv6 traffic to end-users, I am adding my “me too” to this report.  (And if IPv6 Fasttrack works but Fastpath doesn’t, that is kind of a shocking thing to have slide through the QA for this 7.18 release, where IPv6 Fastpath was pretty heavily promoted.  Like, how does such a bug not get caught on the way out the door…)

Это FASTTRACK, а в моём OP я написал FAST PATH! Никаких правил, только пакеты с одного интерфейса на другой.

Спасибо, я удалил все старые правила, вставил новое правило «fasttrack-connection» в начало цепочки «forward», которую экспортировал, затем заново применил все правила и перезагрузился. Похоже, теперь всё работает.

Yes, you’ll need both rules. Also, as documented by @EdPa from MikroTik, some bridge settings like DHCP Snooping cause fast path to be ineffective, as a result, fasttrack will also not work on that bridge (shown as active but the counters do not increase), in those cases you’ll only get “partial” fasttracking when moving packets between bridge and (WAN) interfaces external to the bridge only, not for inter-VLAN traffics (if you keep DHCP Snooping enabled).

У меня версия 7.18.2, пытаюсь включить быстрый трек IPv6, но в Winbox эта настройка пуста, и включить её нельзя. Единственный способ включить — вручную добавить правило фаервола (как предлагали ранее)?

/ipv6 firewall filter add action=fasttrack-connection chain=forward comment="Enable FastTracked v6 traffic" connection-state=established,related  
/ipv6 firewall filter add action=accept chain=forward comment="accept established,related,untracked" connection-state=established,related,untracked  

Второе правило уже есть, а первого нет.

Привет, у кого-нибудь получилось реализовать IPv6 fastpath на версии 7.18 и выше? У меня те же условия, что и для fastpath ipv4, галочка стоит, но счётчики не работают — всё ноль. Как можно проверить, что fastpath действительно работает? Спасибо!
