[Feature Request] IPv6 Fasttrack

Sun Nov 11, 2018 12:25 pm

I was led to believe that the Hex S (RB760IGS) achieves full gigabit throughput. This is not the case with IPv6. Due to the lack of IPv6 fasttrack support, IPv6 throughput maxes out at roughly 500 Mbit/s. That alone is bad enough, but on a DS-Lite connection, IPv4 is tunneled via IPv6, so even IPv4 throughput is limited by the lack of IPv6 fasttrack support. To test that this is indeed the cause of the low throughput, I disabled all IPv6 firewall rules. This allows the router to use fastpath acceleration even in absence of fasttrack support, and indeed then routing IPv6 at full gigabit speed is possible. But what good is that without any firewall capability?

Please add IPv6 fasttrack support, urgently.

+1 obviously in critical demand in the modern world. everything we deploy nowadays is ipv6 with some ipv4 workaround/nat solution.

It's 2019. Time to support IPv6 acceleration.

200 Mbit/s via IPv6-over-PPPoE on hAP ac..

I will support the notion that it's time to bring acceleration to IPv6. Please.

I was not aware that any Mikrotik Products supported DS-Lite, please explain how you support this.

It is my understanding that fastpath is currently only available for IPv4.

They don't support DS-Lite. But DS-Lite is just native IPv6 with an IPIPv6 tunnel to a CGNAT gateway for IPv4. Mikrotik routers can do the tunneling, but lack the automatic configuration and the necessary DHCPv6 features to script the setup. If you know the domain name of the CGNAT gateway (the "AFTR"), you can set up the tunnel manually. See RFC 6333 for details. Be warned though, the throughput will be limited due to the lack of IPv6 fast tracking support. The router can use fast path acceleration only if there are no IPv6 firewall rules.

According to MikroTik's own documentation there is currently no IPv6 fastpath support.

There is not NAT situation anymore with IPv6 (well.... mostly), but a boost in perf could be nice, with IPv6 being the futur and more and more used.

hAP ac2 (and all new IPQ401x based gear) happily can do up to 1Gbps.
i test this regularly with the on-board speedtest (tool speedtest) command.

but ipv6 fastrack is a must.

btw, instead of ds-lite i'd have a nat64 gw :-)
and xlat464 & dns64 resolver in the clients.

Can you explain it a little bit more?
nat64 gw / xlat464 & dns64 resolver in the clients.

Best case will be a config example to get my ISP Provider connection in a Mikrotik RB433 OS 6.44.6 configured.
My ISP provides a 56bit IPv6 Prefix Pool and a IPv6 address per DHCP.
IPv4 is connected thrue a DS-LITE-Tunnel with a AFTR Gateway.

Tested with a AVM Fritz Box everything fine!
But I'm not able to configure it at the mikrotik router
Especially the AFTR Gateway, Ive tried with the ipipv6 tunnel but it dosen't work

How can support in this case i guess I#m not the first one who needs the config in detail.

Would be nice if it atleast scaled right on cpus somehow.
With a simple test using fast.com with more than 2 parallel connections, on a hAP ac2, cpu3 goes up to 100% and the rest of them sit idle, tested with with ROS 7 Beta 2, same thing.
Bandwidth capped because of this under 400mbps out of ~900.
LE: Might be because of PPPoE as my ISP uses IPv6 PD over PPPoE.

I have issue with IPv6 in DHCP and PPPoE, Im not able to get gateway and DNS for clients.

May i Know how it will be come on PPPoE and DHCP.

Maybe in v7 ?

With a ccr1036, I hit approx 2gb/sec per connection, while I can hit more than 9gb/s with ipv4 and fastrack. Of course, if you multiply the connections, you can be at full speed overall, but, it's not ideal.
