With /64 you are limited to a single slaac subnet which should correspond to a single vlan.
Ask your ISP for at least /56.

As long as your datapath bridges your WiFi interfaces to a layer 2 domain with dhcp server it doesn't matter where the dhcp server is running. With local forwarding this bridging has to happen on the CAP, without local forwarding it has to take place on the manager.

And when I do go IPv6, I am convinced that will only be as far as my public IP and the rest of my internal lan will still be IPv4 based so not to worried.

That's not how IPv6 works.

Currently, the switch have 3 bridges and each bridge have it own subnet. That sounds like you are doing a lot of switching in software on the slow cpu instead of using the device's powerful switch chip.

The cAP ac has separate antennas for 2 and 5 GHz, so it might have a slightly better signal than hAP ac2 with its shared antennas. But either way, if you want a good signal you shouldn't hide your APs behind drywall

If you configure it correctly it will work. I didn't check your whole config, but I don't see a bridge defined in /interface wireless cap.

Local forwarding attaches the wifi interface to a bridge on the CAP itself, not on the manager (the traffic stays local on the cap). The bridge to use is defined on the CAP in the same place where you tell it to use capsman.

So, your are complaining that nobody wants to connect to your ap?

If you are using only IPv4 with fasttrack, hap ac2 will do the job. If you need fasttrack disabled and/or good IPv6 performance, rb4011 is the way to go.

RB450Gx4 is probably for some rare in between usecases, when hap ac2 cpu is fast enough but you need more RAM.

Is this because CAPsMAN automatically manages the connectivity and handoffs between my two cAPs at each end of the house when I move from one end of the house to the other?

No, CAPsMAN doesn't do any of this. Your client devices decide when and where to roam on their own.

I think that's only possible without capsman.

You can only achieve that by setting password and vlan id per client MAC address. As you probably won't know all your guest's devices, you would have to set up an access rule for each of your private devices. I wouldn't recommend it, a second SSID is most likely the better solution.

2.4Ghz b/g/n, dual chain. See https://fccid.io/TV7PL64112ND

There's as slight bug in switch chip in IPQ4xxx which bit me and MT doesn't have a solution (yet).

What is the bug? Could you share some information?

whatever

One can argue about "router on a stick" SFP+ setup to lift possible limit to 15Gbps total, but i think those will not be numbers anyone is looking for.

Why not? That 15Gbps is exactly the number I'd expected to see as achievable benchmark limit for this block diagram.

https://forum.mikrotik.com/download/file.php?id=33451 Anybody else wondering why RB4011 CPU-throughput appears to be capped to 10Gbit/s? Assuming both Realtek GbE switchgroups are connected at 2.5Gbit/s each to the CPU (like RB1100AHx4), this leaves only 5Gbit/s possible thoughput for the 10GbE SFP...

1. Use physical security on your ports.
2. You cannot prevent anyone from using "your" SSID, but using WPA2+Radius authentification should prevent MITM.

whatever

Oh boy, it does look ugly with those rack-mount ears attached.

It's a pretty clever way of combining rack-mount capability and desktop case into the same product. Not exactly pretty, but very funktional; I like it.

whatever

No sensor.

whatever

It's the same as with every other 16 MB routeros device: The update is stored in RAM until installed. Just try it.

whatever

What happens if you try to upgrade?

whatever

You shouldn't use local passwords at all for this kind of deployment. Look into asymmetric crypto (ssh public keys) and/or centralized authentication (radius, etc).

whatever

Use system->resources->CPU and tools->profile to monitor CPU usage while running the speed test. Is any of the cores maxed out? If yes: find out what process causes the high cpu usage, try fasttrack, etc. If not: Check cables and interface speed. Are all the involved interfaces running at gigabit sp...

This has already been discussed here two weeks ago. The corresponding topics have been deleted/hidden, so it's probably not meant to be public yet.

whatever

Please stop calling ethernet over fibre "fibre channel", these are two different things.

whatever

It's rather a fcked up design than a bug, this is even documented in the wiki. Documentation suggests allowing "all" and forbidding every unwanted interface. This could easily be fixed by introducing an "allow local" setting. Link: https://wiki.mikrotik.com/wiki/Manual:Simple_CAP...

But if I'm forced to connect a "real" switch anyway I can get all the ports i need from the switch. Want to connect three ISPs? Configure three ports on your switch on separate vlans and pass them through a "WAN" trunk to your router. Want multiple local networks? Separate them o...

whatever

Thank you for the confirmation. While I get that a router is expected to provide only limited switching features and has the necessary CPU power to perform certain things in software, I'm still confused by this decision. Why would I need 10+ ports on a router if it can't do proper vlan switching in ...

I'm looking for a way to do reverse path filtering for IPv6 in RouterOS. I request a dynamic pool via DHCPv6-PD on my WAN interface and use it to deploy separate /64 prefixes on local vlan interfaces. As far as I can tell, the only way to implement something like rp_filter for IPv6 would be a script...

You should really use the firewall to protect your management ports. Yes, there is a _very_ bad bug in old routeros versions, but it's only exploitable if you f*cked up your firewall rules. Only port accessible from the outside is the Winbox port and SSH custom port. But why are these accessible fr...

Imho you shouldn't be using telnet at all, not even in LAN. You shouldn't just firewall it but also disable the corresponding service.

whatever

According to https://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features the Realtek switch chip used by RB1100AHx4 (and possibly also *future* RBs ;)) lacks a vlan table. Does that result in no way of doing vlan filtering in hardware on these devices? The idea, that a lot of the cheap low-end device...

whatever

Wouldn't it be much easier to delay the dhcp client execution on the rpi?

whatever

Try to disable hw-offload on your bridge ports. If the packets can be forwarded in hardware by the switch chip, they will never reach the cpu for filtering.

whatever

https://wiki.mikrotik.com/wiki/Manual:C ... figuration
Your datapath does not include local-forwarding=yes, therefore all your wifi traffic will be tunneled through capsman.

whatever

Edit: why no local forwarding?
I can easily max out 150 Mbit/s downstream with hap ac2 (no capsman) and iPhone 7.

whatever

Sounds like this: viewtopic.php?t=134538

Challenge-Response requires the device to have your password available in plain text, which is the reason why the latest winbox bug was able to leak your passwords, no matter how strong they were. The new login mechanisms allows the device to save only password hashes, even if an attacker manages to...

whatever

Did you disable fastpath/fasttrack? You should.

whatever

The Wiki (https://wiki.mikrotik.com/wiki/Manual:S ... in_CAPsMAN) suggests using

If you take a look at Google's IPv6 data , you will realize that IPv6 adoption in Latvia is negligible. Guess that's one of the reasons for its current state in RouterOS. On the other Hand, there are countries where Dual Stack (or DS-Lite) has become the default for most ISPs. Belguim is already at ...

Don't expose the mgmt interface to the internet? If you have to: use additional security features like port knocking and vpn.

whatever

Wow, thank you for the extensive reply and sorry for my late response. whatever - 1) Bridge VLAN filtering is not so easy to implement on these switch chips. ok, noted. 2) Which examples are missing vlan-header values? If you are talking about the hybrid port setup, then by default it is set to &quo...

Why don't you use a stateful firewall with connection tracking? The first packet of a TCP connection will always be "new", no need to reinvent the wheel by checking flags manually.

Current channel is beta only. If you don't like to participate in beta testing programme, stay in bugfix channel. My hAP ac² came preloaded with 6.41.3; am I really expected to downgrade to 6.40.8 if I wish to run non-beta software? I was under the impression, that "current" means stable,...

1. Switch Menu in Winbox is missing (hAP AC2 - 6.42.4).. Would be nice if someone else can confirm. 2. Configuring it via CLI works and HW offload is working Both confirmed. 3. New Bridge implementation is incomplete (at best) as documented in Wiki. As someone who just got a hAP ac² as his first Ro...
