Have you disabled fasttrack for the affected/all traffic.

Simplest though blunt option is to disable the default fasttrack forward rule.
CPU usage will increase a lot.

Also, having limit-at on just one queue is probably bad. (Means it is guaranteed 50M, the others are Guaranteed nothing)

rplant

I think this might be basically doable, so long as the ISP router can be configured with static routes on it. ie. 10.0.0.x/24 via 192.168.1.2 (the IP address I have assigned to the CRS) If a device on the main ISP LAN wants to connect to a device on your new LAN, it will send the packet to the ISP r...

You could perhaps try you iperf (I assume iperf3) With the -V and -M options.

Using custom/reduced MSS settings to see if it is perhaps something to do with reduced MTU at one end due to pppoe.
And add an appropriate mss adjustment rule if it helps

If the mesh router has the option to disable it's dhcp server, you could do that.

Hi,
License wise:
Not sure there is a limit for raw ipsec.
There is a 500 user one for l2tp.

I would recommend you experiment with wireguard.

You could possibly add a src-nat rule something like

Move it up above any masquerade rules already there.

For generic case, perhaps not. (maybe a container?)

But for a single source ip sending data, you could probably use a dst-nat and src-nat pair of rules, to send the traffic back.

You can run your eoip or other tunnel inside wireguard. Though I would perhaps attempt to set up ipv6 and associated routing on the Mikrotik manually, using one of the /64's.

The S+RJ10 plugs into a 10G sfp+ interface.
The L009 has a 2.5G sfp interface.

That feels like a bug.

I think the Mikrotik radio should likely have its own multicast subscriber list and send it to only its subscribed stations.

I gain the impression that the S+RJ10 still runs quite warm, as its backend has to be run at approx 10.3G
(whether connected on the RJ45 side at 1G, 2.5G, or 10G)

While an actual 2.5G unit's backend runs at 2.5G (* 10/8).

You could also try turning off bridge fastpath in bridge setting

Yeah, that makes sense.

You can put your outbound queue on ether1, and your inbound queue on bridge.

The brass fold down tab is likely to lock the rj10 device into the sfp slot.

Hi,

One option is to have multiple wireguard interfaces with one peer each.

Not sure,

1. Add the pppoe Interface to the WAN interface list.
2. Disable/remove dhcp client on ether1 if it is still present.

Incorrect public key at one or both ends seems to be more common than it should be.
