We have a couple of thousand R11e-LTE6 out in the field and are evaluating the FG621-EA as replacement, but so far I'm not happy with the FG621-EA. In order for it to connect after changing APN or SIM provider, I had to set modem-init="AT+CGDCONT=0,\"IPV4V6\",\"\";AT+CGDCONT...

AFAIK, it's an acknowledged bug. I reported it back in June (SUP-118219) and was told by Sergejs B. : Thank you for the report, we are aware of the particular problem, hopefully it will be fixed shortly. Thanks a lot! I'll report it, too. EDIT: reported as SUP-131641. That being said, I recommend 2...

That's not the problem at all. Sorry, but that's wrong. Again: You don't know all constrains and that's okay. Please accept that. I've used these ULAs here to create a simple minimal example. Reality is more complex. All I want to know is why in the first case only one address survives the reboot w...

I know that article and I understand why you advocate using a larger net. For most applications that is definitely the way to go. But we have lots of other constrains that I didn't mention here, some of which we don't have control over. Mobile carriers limiting us to ::/64 per SIM card is only one e...

Using a single pool is not an option here. We have a few thousand devices and each has it's own fd10:x:y:z::/64 prefix. In certain environments, we need an additional network that we can advertise to hosts, and this can't be in the fd10::/16 range.

I'd like to have multiple IPv6 addresses using "from-pool" on the same interface. If the have the same "address=..." specified, only one of them survives a reboot. Minimal working example (tested in RouterOS 7.11.2, but I've seen this behaviour already in RouterOS 6): # before re...

Thanks! I already had a rule for LLDP in place, but I missed CDP. That was the solution.

Hi, I am trying to drop MNDP packets in a bridge. This is the setup: A <-> ether3 B ether1 <-> C "B" has a bridge with ether1 and ether3, because it needs to be transparent for most traffic. But I don't want to forward MNDP packets between A and C. So that's what I have on B: /interface br...

Well, the SIM supports (steered) roaming and can connect to all networks, even though by default it prefers its native provider. But scanning only shows its native network.

I know cellmapper.net and I agree it's useful. But I was hoping that I could scan all networks with the same SIM card. Using multiple cards is not feasible for my application (remote locations distributed all over the country, very restricted physical access).

I think I figured out what the difference between the two routers is: The SIM cards in those routers come from different service providers. It seems that cell-monitor only shows cells that belong to the service provider that issued the SIM card, even though the SIM card is configured to roam in all ...

I've got two routerboards with R11e-LTE modems. Both modems are at firmware MikroTik_CP_2.160.000_v013. One routerboards is at 6.45.3, the other one is at 6.46. With ROS 6.45.3 "/interface lte cell-monitor lte1" shows results, but the EARFCN column is empty. With ROS 6.46 I don't get any o...

This fixed it for me:

I'm running ovpn-client on my MT devices and the openvpn server on a Debian box. After upgrading from 43.x to 44.1 I get lots of "IP packet with unknown IP version=0 seen" in my server logs. I've solved this by downgrading to 43.13 now, but I hope this gets fixed in stable.

I downgraded to 6.43.13 now, and the log messages are gone. I hope this gets fixed in stable.

Hi! I'm using /interface ovpn-client to connect to an openvpn server running on a Debian box. After upgrading from 6.43.7 to 6.44 my server logs are flooded with messages like this: IP packet with unknown IP version=0 seen The server is running openvpn-2.4.0-6+deb9u3. The client config is: /interfac...

Hi! I've got a RB922UAGS-5HPacD which has one USB port, and I've got two devices with serial ports that I need to access remotely via the RB922. If I add a 2x RS-232 <-> USB adapter (FT2232) it appears in /port as one device with two channels. Is it possible to set the baud rate for each channel ind...

Shouldn't make a difference, /ip address add address=192.168.3.73/24 interface=ether1 /interface ethernet set [ find default-name=ether1 ] disabled=no /ip tftp add ip-addresses=192.168.3.0/24 allow-rollover=yes req-filename=some_file.scr real-filename=some_file.scr read-only=yes Should work too (et...

If I connect Orange Pi and RB922 with a straight ethernet cable, I can see the link coming up on the RB922 (100M-half), but u-boot can't ping the RB922 and tftp times out. That's the first thing I'll troubleshoot, why half duplex? try issuing some "ip link" commands or whatever appropiate...

Update: I've found a work-around, but I'd still like to know what's going on here. If I change the RB922 configuration from /ip address add address=192.168.3.73/24 interface=ether1 to /interface bridge add name=bridge-lan /interface bridge port add bridge=bridge-lan interface=ether1 /ip address add ...

Hi! (EDIT: For a work-around, see my answer below. Nevertheless, I still want to understand what's going on here, so if you have any clue, please let me know!) I've got some trouble with u-boot running on an ARM board connecting to a RB922UAGS-5HPacD, and I'm not sure where I should start digging. E...
