Re: Script to verify incoming IP address and block it in firewall (add to address list)

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...

Re: CRS109-8G Crashes/reboots often

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'...

Script to verify incoming IP address and block it in firewall (add to address list)

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 ...

RB2011 PPTP Client cannot connect

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 ...

Re: CRS109-8G Crashes/reboots often

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...

Re: CRS109-8G Crashes/reboots often

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 (...

Re: CRS109-8G Crashes/reboots often

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...

Re: CRS109-8G Crashes/reboots often

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?

Re: CRS109-8G Crashes/reboots often

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

I definitly need to buy a replacement adapter.

Re: CRS109-8G Crashes/reboots often

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...

Re: CRS109-8G Crashes/reboots often

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...

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 ...

Re: CRS109-8G Crashes/reboots often

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 ...

Re: No response from subnet over PPTP

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 :D :D 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 :)

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.
