Where do you do such clamping? It depends, some VPN types have a setting for it. eg. GRE, also l2tp server profiles Otherwise you would do it in a mangle firewall rule. (You also get more control here) I have one like: /ip firewall mangle add action=change-mss chain=forward comment="clamp mss ...

It seems maybe a bit flaky.
Perhaps contact your Mikrotik distributor.

I would try tcp mss clamping matched to below whatever the underlying vpn mtu is.

My GUESS is that it is like L2TP, etc with psk.

A couple of thoughts. 1. Usually if you are given a static ip address by your ISP, you don't put it in manually.

You often need to src-nat the port from your ntp-client (So it looks like it's coming from a high port rather than port 123) As ISP's, ntp servers will often block ntp from port 123, (which Mikrotik's ntp client uses).

One thing I checked was:
You want the wireguard interface to be a member of the WAN list, (and very likely don't want it to be a member of the LAN list)

rplant

That seems like it should be running as a basic L2 switch, so should not be using much CPU at all
(given its default configuration usually contains very little)

Perhaps export and post its config.

Hi,
Given the routed configuration you have.

A possible option is:
You could create an ip vrf (eg. vrf5)
And attach to it the interfaces bridge5, wlan2 and ether5.

That might work.
Sorry I know little about vrfs.

rplant

You don't seem to have any masquerade/srcnat on ether3.

rplant

Based on the original question, You should have NO dhcp (server or client) or ip address on either bridgeWL1 or bridgeWL2. However this does make it difficult to manage. If these 2 bridges and attached interfaces are the ONLY connected interfaces on the router, you can probably add a dhcp client to ...

rplant

Hi,

You probably shouldn't have ip addresses on these 2 bridges/interfaces.
That should be handled by the modem, which would have a dhcp server on it.

You can possibly add a macvlan to the vlan, and then add your new PPPoE client to the macvlan (which has a different mac address).

Assuming near default config. A quick and dirty solution. I would create 2 additional bridges. bridgeWL1 and bridgeWL2 Both with protocol-mode=none (no rstp) Then in bridge ports add ether1 to bridgeWL1 and move WLAN1 to bridgeWL1 and also move ether5 and WLAN2 to bridgeWL2 Remove the ip dhcp-client...

Another possibility:
Some special handling may be required if you have multiple public ip addresses on the router.

Ignore this, mine seems to handle this fine.

rplant

One possibility. Seems unlikely, but you do have a wanIP as an address list. If you have multiple wan interfaces, and the packet is coming in from one interface, and leaving via another (the wan interface with the lowest metric). This could occur. You would need to mark your packets (or similar) so ...

rplant

One other thought, (Somewhat more like my original thought) You could perhaps make a new pcq type queue, based on pcq-upload-default, but with a 24 mask. (So everything from 10.0.1.x will be counted together) Then back to no marking, and fast track allowed. The low rate lans will be prioritised over...

Sorry, I should read things a bit more thoroughly. Unfortunately, the 3011 seems to not be great under v7. Perhaps what you have will be good. Though I do not understand why you have a limit of 100M on the backup traffic. You will likely need to add all the packet marks to the parent (WAN-Shaper) so...

It would be very functional to be able to add a description for each connection that you save and thus identify more quickly to which mikrotik equipment I want to connect I am assuming you a speaking of the managed tab in winbox.

rplant

As a start, I would be inclined to just put a single cake queue attached to the WAN interface, to see how well (or not) it works. (With no packet marking for shaping) Set it up for 500M, and a bucket size of 0.005-0.01, (or your settings) and see how it goes. You will need to create a new queue type...

Some possible options: If you make a custom interface list and add all the ports you want (but not the bridge) to this list, you can make ip discovery use this list and it will only target those ports.

2. Yes and no Since the device is now a (dumb) switch it has no way to filter anything. The input firewall chain still works.

Hi, My observations: Actually wireguard in mikrotik does attempt to use the IP address that the incoming packet was sent to. Looking at the packet on the output chain is too late.

Hi, My guess is that you need to run dhcp, so the ISP gets the MAC address of your router, so it can send packets to it. It may not use arp discovery, the dhcp mac address possibly gets recorded into the radius server, and that is where the routers packets get sent too. (I believe Mikrotik's do this...

Some thoughts. 1. Don't use L2TP at all, use wireguard, its easier/better. (L2TP is slowly being discouraged) Wireguard: You only need 1 port.

Another thought The arp table can get very big these days. There is an arp timeout value on interfaces and bridges.

My guess is that perhaps the end devices don't know how to (or don't want to) route back to the wireguard IP address range.

You could add a source nat rule that if the ip address is the wireguard range, it gets masqueraded and see if that works.

My thought is to disable the fasttrack rule and see if that helps.

Fast tracked traffic does not get packet/routing marks applied.

If it helps, you might be better off with routing rules.
As they should continue to work with/without fasttrack.

Rules look ok. Some guesses Does the mikrotik have the same internal ip address as the old router? Presumably .100 and .102 are set up with static ip configurations.

Have you disabled fasttrack for the affected/all traffic.
