Hello All! I didn't want to create a new topic, as my problem is almost identical as the OP's, however - the difference is that the modem will never re-register itself after deregistering. The issue existed on ROS 6.48 with LTE firmware 028 and it still exists now on ROS 7.2.1 + LTE 033. What I've n...

albercik

That's not weird. The srcnat and dstnat chains of the firewall only handle the initial packet of each connection, and the verdict of these chains is stored in the context of the connection in the connection tracking module of the firewall. So you're saying that each time I change src-nat rules on m...

Got an update. Because I need my services up and running asap - I've decided to set up a web proxy on RPi and i've disabled all my IP's except of one (.50). That did the trick (almost): everything is working fine from the outside, there are no pings lost and all of my services are working fine. The ...

Hello All, I have a problem which I can't handle. My ISP gave me 5 IP addresses. Let's say it's 1.1.1.50/29, 1.1.1.51/29, 1.1.1.52/29, 1.1.1.53/29 and 1.1.1.54/29. My gateway is 1.1.1.49 and my network is 1.1.1.48. Now, all of the addresses are assigned to ETH1 of my RB2011. I also have two subnets ...

Hi All! I've upgraded my LHG LTE6 (and SXT LTE kit v2, but it doesn't have this issue) from ROS 6.48.2 to 6.48.3 and I can see that there's some problem with a LTE connection. After reboot/startup - everything works fine, it connects to my network, registers and the link is up. Great. But, after few...

albercik

post your configs, otherwise have no idea what you have done LOL. I have no idea also, but my configuration wasn't as perfect, as I previously thought... After two hours - my RB750 became really hot and fried... It was the oldest RB750 I've had (three electrolytic capacitors on board). So I've repl...

albercik

No, this is really cool and different so interested LOL. Can you add the config of each LTE /export hide-senstive file=anynameyouwish I am still thinking only one bridge is needed. On the trunk port between the LTE and the router there are two vlans, ONe goes to DHCP client on the router, the other...

albercik

@anav, I feel your point, but let me repeat once again: my ISP gave me only SIM cards . The modems are two Mikrotiks (one SXT and one LHG) working in LTE passthrough mode with two VLAN's configured: one VLAN is for traffic, and the second one is for management. The bridge is only because the TWO of ...

albercik

Hi and thank you for the reply. You only have two vlans defined or I should state only two with DHCP serving capacity on the router. 200 and 201?????? Only two with DHCP (the are networks for my work and fun). Where should we assume vlans 10, 20, 100 are coming from??? VLANs 10 and 20 are from LTE m...

albercik

Hi, Thank you for the reply. I've changed the Internet VLAN IDs to vlan10_sxt and vlan20_lhg. Unfortunately - it gave me nothing. Here's my config: # apr/26/2021 17:25:04 by RouterOS 6.48.2 # software id = IDVH-06WR # # model = 750 # serial number = 2198018B1434 /interface bridge add arp=proxy-arp n...

albercik

Hello All, I've read almost every topic I've found here (and somewhere else too) that could by close to my set-up, but unfortunately - nothing gave me the answer. Also, all of my tries went to nowhere. Here's my setup: 1 x RBSXTR with LTE passthrough to VLAN "vlan1_sxt" and second VLAN &qu...

albercik

Thank you @mkx for the clarification. I do use a standard car battery (I will buy the touristic accu next month - first I want to test the solution) and yes, it's 12V. Power supply is 24V. It's good to know there's this simple logic - it will be useful in my work also :) Thank you in advance and bes...

albercik

Unfortunately - my device is not under warranty anymore so RMA is not an option for me. As I stated before - I've moved the card to slot 2, so we'll see if it helps. As @angriukas wrote - even reboot didn't help. We'll see if there will be any problem with the sim in second slot and if the usb power...

albercik

Hi, Thank you all for the replies. I've turned on lte logging to disk and swapped the sim card to another slot. I've also written a script that checks the status of a simcard (if it's present) and if not - it performs usb power reset. If the simcard won't be avalable after 1 minute - then it perform...

albercik

Hello All! I'm not sure if it's hardware- or software-related question... The case is that I use three Mikrotik's in my summer house: - SXT LTE v2 - RB751 - cAP The SXT is powered over PoE from the solar panel and battery. The RB751 is powered by the AC/DC adapter and passes current over fifth port ...

albercik

Hello Everyone, I have a problem with SXT LTE kit v2. In general, the device works flawlessly, the connection is stable and fast, but... from time to time the Internet goes down, and the interface status says "no sim card inserted". I can reboot it etc, but it won't help. I have to take a ...

albercik

Most Telco providers can assign static IPs for SIM cards (for an extra cost) This is the way I am allowing SIP access for some mobile clients. In an era of reducing costs to the absolute minimum - none of my Customers will agree to that :D At this moment - I have automated the process by updating a...

albercik

Thank you for the reply, and sorry for the delay - I'm overworked recently. Unfortunately I can't allow only specific IP addresses as it's a connection to SIP server and my Customer's employees are using sip-phone app on their phones, so it's quite unpredictable what will be the user's IP subnet nex...

albercik

Okay, I think I've figured it out. I wanted to test my CRS109 if it will work with LTE USB dongle. But it couldn't find it. So I've removed a device's cover and it turned out that somebody was trying to repair a USB port on RB. It has traces of ironing and whole usb connector is broken. Also, there'...

Hello, I'm preety new to MT and I'm totally new to ROS scripting... Recently, I notice a large number of unsuccessfull attepmts to log in into my VoIP server at home (actually it's just a Raspberry PI with debian and FreePBX+Asterisk). Each time I check - the IP address is from China, so I wan't to ...

albercik

Hello All! I've finally managed to move to RB2011 from CRS10, but one issue still remained. I have PPTP VPN server on my MT, so I can access my office and datacenter remotely. Basically - in my DC there's good old RB750 which has a site-to-site PPTP tunnel configured to my RB2011 and I also connect ...

albercik

Strange, Before I even had a chance to move my config from old HW to new one - the CRS started to reboot again. I suppose it's a hardware malfunction :( Is there any place I can find a schematics/diagram of routerboard for this model? I'd like to perform some checks as I think that it's a faulty cap...

albercik

It's because the connector is slightly different than it should be. MT uses a standard DC jack 5.5/2.5 mm and the adapter uses 5.5/2.1 mm and it doesn't stay tight. Even a smaller move causes shutdown and reboot. However.... I now have a brand new RB2011UiAS (without WiFi radio) and new RBcAPL-2nD (...

albercik

Okay. So I've made some reserach. As I didn't wanted to waste my money on a DC adapter in case it wasn't an issue - I've used an 19V, 3.8A DC adapter coming from some old ASUS notebook. MT is working flawlessly without any restarts or crashes with WiFi radio turned on. I've tranasferred almost 200GB...

albercik

Ok, I've been looking for some DC adapter. And I'm confused a little bit.

Basically, there two types of adapters: impulse and transforming. Which one should I choose for my MT?

albercik

So far, so good. Since disabling a wifi interfaces - no reboots, no crashes, works as desired.

I definitly need to buy a replacement adapter.

albercik

BTW - I've heard that CRS109 can be powered on ETH0 using PoE. Is that a thruth? I have some PoE power supply in my basement... According to specifications that's true. But ... it's not standard PoE (is in 802.3af/at), it's passive. So it's quite possible your PoE power supply wouldn't do it (there...

albercik

Yes, the wireless radios draw quit a bit of power. It sounds as if the CRS109 meets your requirements, if that is the case, and it was me, I will buy the correct power supply, add a virtual WLan and voila, you have 2 x SSIDs Yes indeed - CRS109 fits my need perfectly :) I've made a lot of customiza...

albercik

But the device comes standard with a 24V 0.8A adapter??? https://mikrotik.com/product/CRS109-8G-1S-2HnD-IN yes, I'm aware of that, but I'd bought this MT second-hand as I had low on-start-budget and I didn't know if it will fit my needs (turned out MT rocks ;) ). It came with 12V DC adapter and it ...

albercik

... But... Before making this upgrade I've made another observation: when my phones are turned off and my laptop is docked (networ connection via ethernet port) - everything works seamlessly. I've transferred over 10GB of data and nothing happened. As soon as I've turned on my phone and played some...

albercik

Okay. I've made upgrades following your guidelines. Now I'm running RouterOS 6.42.11. None of the settings were lost nor needed to be updated :) Let me say - this was the easiest upgrade I've ever made on any electronic device :) But... Before making this upgrade I've made another observation: when ...

albercik

Thank you for the reply. Please, forget I've ever asked for remote upgrade ;) but upgrade from 6.40 to 6.41 will change the way ethernet ports are handled (previously there was master-port, now it's all off a bridge). If old configuration is not quite straight-forward, then upgrade magic might mess ...

albercik

Hello All! I have a CRS109-8G-1S-2HnD router at my office. A router was working fine until few months ago it became to crash/restart itself. It happend once per few days so I didn't gave it much attention, as I'm quite busy man ;) But now - it's a horror. The router reboots itself from few times a d...

albercik

Hmm, that sound easy

At this point I have all the traffic coming to 0.0.0.0/0 routed to the tunnel, except of my MT1's address for the vpn to work

It's messy, but it's effective at the moment.

I'll give a try to Your suggestion during the weekend and I'll report back if it's working

albercik

The response comes out of the server to MT2 (10.0.2.1), then is SRC-NATted to 10.0.1.1 (I've tried every possible IP here) ... I don't understand this part. Are you trying to srcnat packets from server on Mikrotik2? Why? Also, srcnat on Mikrotik2 can't do anything to reply packets that belong to fo...

albercik

Hello All! I have a little problem with my routers configuration over PPTP. What was till few days ago: My router (MikroTik1) standing at my desk, with five public ip addresses assigned and VPN server enabled. Also I had my servers standing under my desk connected to the mikrotik. Ports where forwar...

albercik

It depends on country and operator, but even if you do get a public IP on the mobile device, if it is changing Here, in Poland every mobile Internet client has private, dynamic IP. If you want public IP - you have to pay. If you want static - you have to pay even more... But don't worry - as I said...

albercik

your wife will find a better purpose for them than a public address? Oh no - I will have a public, static address at the destination in DC. But only one. At this moment - I work daily at some company, and - in a meantime - I try to run my own business. And more than one public IP address will be wa...

albercik

Hmm, I'm confused a little bit... :D But OK, I'll try to set this up as you said - on my kitchen table, where I'll connect my "remote" router VIA mobile Internet (so it will be completely separated from my home ISP) and I'll test it for a while (probably it will be a very short 'while', be...

albercik

Thank you Sindy for the reply. It look way more difficult than I thought till now... I'll try to set this up thanks to your post. Just to clarify: yes - I use DHCP at my home router (company-bridge) as there are DHCP-assigned devices running (printer with WSD, my laptop, another desktop etc..). At t...

albercik

Thank you for the information. I'm not a advanced user of MikroTik, so I need a little more explanation :) Hope you don't mind. What I understand is that I need to set-up a L2TP server on my home router and L2TP on my remote router. I don't need a dhcp for this connection, as both devices will have ...

albercik

Hello All! I have a little problem with (planning as for now) site-to-site VPN between two mikrotik devices. But short story first: I'm running a small company that produces small CRM-like apps. To be honest the first one is actually getting developed and I have no customers yet ;) At the very begin...
