Hi All, I have spent a couple of hours on trying to setup an OpenVPN server on my Mirktoik CCR1036 (Hoping to replicate this for end users) I have tried multiple different guides and each time I come back to the same error message. I will forward my config for the OpenVPN server as well as my Windows client config.

Hi Vaughan, I dont have a setup that I can send a config for handy. But i think i was using 1500. The modem was directly connected to the router. The apn and all 4G services and nat are controlled in the stick nkt the mikrotik as they are a router and basically present an ethernet connection over the usb port.

Huawei E8372
by Vaughan Wickham 29 Mar '18

Hello, I've made some progress in troubleshooting my issue. Turns out that the performance issue is not the dongle at all. Am yet to fully resolve (and thus understand) the issue but can advise that the issue may be a routing issue or some sort of network configuration issue. The scenario that I have is as follows: User PC's Main router (main link down) 2nd router (use backup link) 4G dongle I need two routers, because the main router doesn't have a USB port, and I want to add a backup link without discarding the existing equipment. What I have just tried is connecting a PC directly to the 2nd router and testing the 4G dongle from there. When I do that the performance is the same as when the dongle is connected to a PC. So the issue has to do with the routing between the Mikrotiks - or something like that anyway. The issue is not the 4G dongle itself. Appreciate the feedback from those who responded. Thanks Regards, Vaughan

Huawei E8372

29 Mar '18

Hello, I've been testing an E8372 USB 4G dongle with an RB951Ui-2HnD router According to https://wiki.mikrotik.com/wiki/Manual:Peripherals the E8372 works My experience has been that it "works" to some degree. Connecting to some Web sites (e.g. www.smh.com.au ) works consistently, yet connecting to other Web sites (e.g. any speedtest site does not work at all). In contrast, when the dongle is connected to a USB3 port on a Windows PC, the performance of the dongle is perfect. Also accessing the Web portal of the dongle seems quicker when the dongle is attached to the Windows computer versus the Mikrotik. I'm pursuing a couple of avenues regarding troubleshooting - The Mikrotik has a standard USB2 port and this may not be supplying the required power for the dongle o I have ordered a USB2 hub with an external power adapter which will supply the power requirements of the E8372 (5V and 750mA). So will test this soon. - I've not been able to configure the APN for the 4G service provider in the LTE properties. There is no error, but the APN is not saved. I am able to save the APN in the 4G dongle's own firmware/web portal, but I'm not sure whether this is used when the traffic is traversing the LTE link of the Mikrotik So the questions that I have are: 1. Is anyone else using an E8372 with a Mikrotik? a. If so, what is your config? b. Are you using a powered hub c. Did you need to save the APN in the LTE properties? 2. Is anyone using some other 4G USB hub with a Mikrotik? Thank you Regards, Vaughan

Telstra Frontier Modem/Router with Failover into MK Router
by Matt Hall 27 Mar '18

27 Mar '18

Hi Everyone, The new Frontier router/modem (Technicolour DJN2130) from Telstra has 4G failover built in but if you bridge it failover doesn’t work. I’ve tested this by unplugging the WAN port from the accompanying cable modem (Netgear CM450-TLAUS) and also by unscrewing the fibre cable. 4G won’t kick in. If you do the same with the factory settings config, 4G kicks in. I’d like to route and run Wireless from my MK router but am unsure about a few things. Basically I’d like the Frontier to do as little as possible. So far I would do this on the Frontier: Under WAN Services 1. Turn off NAT-PNP 2. Turn of UpnP? 3. Turn off secure mode? (not sure what that is). 4. Turn off Wi-Fi 5. Turn of DHCP Server 6. How should I setup the Firewall? I can’t turn it off completely it seems. Firewall settings are: Low mode, the firewall will allow all outbound connections. It will reject unknown incoming connections but acknowledge the presence of the gateway. Normal mode, the firewall will allow all outbount connections. It will silently drop unknown incoming connections. High mode, the firewall will allow outgoing connections to the following services: HTTP, HTTPS, SMTP, POP3, IMAP, SSH. It will silently drop unknown incoming connections. User mode, you can configure each individual rule of the firewall as well as the default behaviour. User defined options are: Answer Internet ping On/off Outgoing default policy: ACCEPT/DROP/REJECT The outgoing policy defines what is done with packets coming from the LAN devices toward the internet. Setting it to REJECT or DROP will forbid any internet traffic from the LAN unless explicitely allowed by a firewall rule. Incoming default policy: DROP/REJECT The incoming policy defines what is done with packets destined to the gateway. They can be either REJECTED (the gateway will notify the sender they were rejected) or DROPPED (the gateway will silently discard those packets). Then to manually add a new rule options are: 1. Action: ACCEPT/DROP/REJECT 2. Protocol: TCP, UPD, TCP/UDP, UDP Lite, ICMP, ESP, AH, SCTP, all 3. Src IP 4. Src port 5. Dst IP 6. Dst port Then firewall rules for IPv6 follows the same protocol. Thankyou, Matt Hall Sydney

As an aside, have you seen your non-Apple clients maxing out at 54Mbit TX rate on 2.4GHz as per this thread? https://forum.mikrotik.com/viewtopic.php?f=7&t=102908 At my place Apple devices are fine but anything Android - including out late model Samsung phones refuse to go above 54Mbit TX. I am surprised this isn't resolved and seems to be in the Too Hard basket for Mikrotik! This is a problem anywhere you put in loads of Mikrotik devices.

Mikrotik - Wireless Issue on hAP and hAP ac lite
by Ben Farmer 06 Mar '18

06 Mar '18

Hi guys, Hoping any of you can help. We're seeing weird issues with our Mikrotik client routers in deployment, specifically with the 2.4GHz wireless on the hAP and hAP ac lites. This issue we're seeing seems to affect the 2.4GHz wireless card (Atheros AR9300 in both models) but does not affect the 5GHz card in the ac lite. Customers are reporting to us the inability to connect to wireless at times, such as invalid security key or failure to connect messages (depending on the customer device). The wireless interface itself will show as running, but with no clients connected. No error messages are indicated in the log about exchange key timeouts or anything similar, like you'd expect. Doing anything that performs a soft-reset like operation on the wireless interface will allow the customer to connect again for a period of time. This can include: - Doing a wireless scan. - Doing a frequency usage scan. - Changing channel. - Changing SSID. Basically any option you can change will fix it, even rebooting the router. We've tried all different types of software from 6.39 through 6.41, even the latest rc (6.42rc35). We've seen this issue for at least three months now, if not longer. It's not isolated to a particular site either, as we receive reports daily from other customer locations with the same issue. Initially we thought it was interference, but even then we have customers with very low utilisation and still seeing this issue. We have reported a case with Mikrotik, but their most recent suggestion was to post in the forums to see if anyone else was experiencing this issue (which surprised me, generally they direct you to support if you write this sort of stuff in the forums). Below I've included a brief output from the router showing the way this interface is currently set up. Have any of you seen this type of issue on either this wireless card or others? /interface wireless security-profiles add authentication-types=wpa2-psk eap-methods="" mode=dynamic-keys name=wlan1 supplicant-identity=room-403 /interface wireless set [ find default-name=wlan1 ] adaptive-noise-immunity=ap-and-client-mode band=2ghz-b/g/n country=australia disabled=no distance=indoors frequency=2462 mode=ap-bridge security-profile=wlan1 ssid="Room 403" wireless-protocol=802.11 Regards, Ben

Bulk net-installing
by Thomas Jackson 05 Mar '18

05 Mar '18

As someone with a large pile of hAP devices that need to be netinstalled (both to run a config script, and to get them onto the right version of ROS), my options appear to be a) spend all day laboriously processing one device at a time, b) try and find someone else to push the job onto, or c) figure out a way that I can run the process in bulk. Before I spend more time reverse engineering the netinstall process to try and replicate it en-masse, how do others typically approach this? My other thought is to use flashfig with a line in the script to pull down the right ROS version as part of the process, the downside there is that (if my understanding is right) our config is not "burned into" the device so if they are reset in the field they'll go back to the factory-default Mikrotik configuration which isn't ideal in this environment.

queue noob
by Karl Auer 05 Feb '18

05 Feb '18

I bought an HAP ac lite, intending to use it as a throttle between a bunch of evil leeching wifi users and a client's tender defenseless Internet router. I have had a test unit (an older 951 unit) in there and used the bandwidth command on the relevant ethernet port. That worked a treat. Turns out none of the interfaces on the HPA ac line support the set bandwidth command :-( So I have turned to queues. I cannot figure them out. This command should IMHO limit the total bandwidth coming IN to ether1 to 1 megabit, and the total bandwidth for traffic LEAVING ether1 to 500 kilobits: /queue simple add target=ether1 queue=ethernet-default/ethernet-default max-limit=500K/1M But when I do that, nothing moves over ether1 (which is the link between the HAP and the Internet router). So I deleted that queue and tried this (192.168.100.0/24 is the network containing the leeches - wlan1, wlan2, ether2/3/4 bridged): /queue simple add target=192.168.100.0/24 queue=ethernet-default/ethernet-default max-limit=500K/1M Traffic flows over ether1, but this in no way limits the bandwidth to anything like those values. If I use 10K/10K instead and then download a file in Firefox, I see the transfer rate start at 12KB/s (kilobytes per second) and creep steadily up to around 100KB/s by the time the whole 50MB file has been downloaded. That's in stark contrast to the 1 or 2 megabytes per second I get without the queue, so *something* is happening, it just doesn't seem very predictable. Ideas would be very welcome...
