MikroTik User Meeting (MUM) in Australia?
by Mike Everest 25 Mar '24

25 Mar '24

Hello everyone! Since the last official MUM event to be scheduled (Prague, Czech Republic, March 2020) was cancelled in 2020 due to the arrival of COVID, MikroTik have stated that they have 'temporarily' ceased running MUM events in favour of concentrating on their YouTube channel production. So far, there continues to be no MUM event planning for the foreseeable future. Having attended all 4 MUM events in Australia to date, as well as several international MUM events, I've been greatly missing the opportunity to hear from our MikroTik peers around Australia and the world, and to mix with all my favourite MikroTik folks (you know who you are! ; ) and to meet new MikroTik converts, enthusiasts and pros. So I've been thinking about the concept of running our own MikroTik event sometime later this year or during first part of 2025, and interested to hear opinions from everyone out there in MikroTik-Land about whether such a thing is worth exploring further.. I've thrown together a quick survey aimed at getting a feel for whether there might be sufficient interest to run such an event, and (of course) how much it would cost us to run it! ; ) I'm hopeful that I could waylay about 5 minutes of your time to respond to these questions - EVEN IF you have zero interest in attending (that is just as useful information as any!) I'll happily report back here on a summary of responses :-} Here's the survey link: https://www.surveymonkey.com/r/TJ9LJCQ Thanks in advance, and hope we can get something up and running and see you all there! : ) Cheers, Mike.

MT as a "media converter" - wifi to wired
by Karl Auer 18 Mar '24

18 Mar '24

I'm trying to use a spare Mikrotik router - an old 951G-2hnD - as a sort of media converter. The idea is that it associates with a mobile phone hotspot, and provides wired access to it. However, I want LAN-side devices to get their IP addresses from the phone, not the Mikotik. To that end I first reset the router to the default configuration. Then I configured the wireless interface as "mode=station-bridge", and added the phone's SSID. In the relevant security profile I set authentication-mode to wpa-psk and wpa2-psk, and put the phone's key into wpa-pre-shared-key and wpa2-preshared-key. The wireless interface and all the LAN ports are already in a bridge. I split one off and moved the dhcp-server and IP address to it so I have a management interface. The bridge thus has no dhcp-server on it, and no IP address. I was sort of expecting that to work, but a client connecting to a LAN port does not get an IP address. The wireless interface does not enter "running" state. SSID and passphrase have been checked. The phone definitely supports wpa2. I can connect to the phone from a laptop. There are no firewall rules that would affect the bridge. What did I forget? Regards, K. PS: Context: Internode shut down our ADSL link with no warning. They say they emailed me, but they didn't. So I am trying to turn a mobile phone hotspot into a WAN connection :-) -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Karl Auer (kauer(a)nullarbor.com.au, he/him) work +61 2 64957435 http://www.nullarbor.com.au mobile +61 428 957160 Please feel free to deal with this email during your own working hours.

High CPU and latency spike on RB750Gr3 during downloads
by Chris Lee 04 Mar '24

04 Mar '24

Hi all, Am running RB750Gr3 firmware 7.13.5 with the out of box factory configuration for internet router. I have disabled RSTP on the bridge. On NBN FTTP 100/40 plan with NTD connected to eth1 on the RB750Gr3. Rest of my internal LAN is connected to eth2. When I max out a download or run a speed test at 100Mbps I find the CPU on the HEX is getting up to 30-35%, and on upload around 20-25%. At the same time I see in all my pings beyond my first hop ISP gateway that I get a big spike in latency which feels like the Mikrotik is struggling to process the traffic inbound. I thought the RB750Gr3 was good for up to Gigabit speeds, but even then I'm only asking for 100Mbps - is there anything I need to tweak further in the configuration to fix this or should I be looking at a newer router like the L009 series, will that provide smoother throughput ? Thanks, Chris

Mangle new routing mark from router traffic
by Steve at Digitronics 02 Mar '24

02 Mar '24

For a long time now I have been steering traffic from the LAN through the router using a <mangle : prerouting : new routing mark> and a routing rule sending that new routing mark out a specific interface. Easy and reliable. Now I want to do the same thing for traffic from the router itself, but it doesn't want to work. It seems the prerouting chain is only for traffic from interfaces, not the router itself, and I can't apply a new routing mark unless it is from the prerouting chain. Catch 22. Am I missing something? Using ROS 6.49.

OpenVPN implementation ROS 6.49
by Steve at Digitronics 01 Mar '24

01 Mar '24

Can anyone confirm for me that the OpenVPN implementation in 6.49 works with VPN providers' OpenVPN servers generally? There is chat that the OpenVPN implementation in ROS is not 'open' and I would rather be sure before I spend more time trying to get it to work with VPN service providers. -Steve

Performance on CCR2216-1G-12XS-2XQ
by Shane Clay 18 Feb '24

18 Feb '24

Hi All I've got my hands on a couple of CCR2216-1G-12XS-2XQ fitted with XQ+85MP01D 100G transceivers. Just doing some initial testing using the built in BTest Server & SpeedTest tools as a bit of initial benchmarking. So far I haven't been able to get up to 100G. The instantaneous throughput I see in the interface list is round 50G for TCP and 75G for UDP. There is absolutely no config on the devices (queues, firewall rules, etc). Interfaces are showing auto-negotiation at 100G full duplex. My guess is that this tool isn't up to the job of maxing out the link but iPerf would probably get it up there. Thoughts?

CCR2216-1G-12XS-2XQ compatible with 10G SFP+
by Shane Clay 29 Jan '24

Hi All My research is coming up short! Can anyone confirm (or not) if the SFP28 ports in CCR2216-1G-12XS-2XQ are backwards compatible with SFP+ 10G transceivers?

EP06-E dropouts
by Jason Hecker 26 Jan '24

26 Jan '24

I have an LHG with an EP06-E module fitted running to a tower about 10km away connected to Telstra. It's been OK for the most part but lately the 4G link has been flapping several times a day, sometime with long periods of silence. The logs show nothing awry apart from the LTE link going down and DHCP not happening. Has anyone else noticed robustness issue with this module? I have set system reboots at 5am to try and help but it keeps happening through the day.

/31 Deployments for Point-to-Point links
by Christopher Hawker 09 Jan '24

09 Jan '24

Hey all, Trying to stand-up a BGP session between a CCR2004-1G-12S+2XS and a CCR2004-16G-2S+ using a /31 for the link. I'm able to ping across the link no problem, however, the BGP session doesn't establish. I'm attempting to move an existing session from a /30 where it works in order to conserve IP space. Is there some skullduggery going on, or is 7.13 just not RFC3021-compliant? Thanks, Christopher Hawker

RBwAPG-5HacT2HnD losing 5GHz radio?
by Damien Gardner Jnr 22 Dec '23

22 Dec '23

HI all, Kinda pulling my hair out with this one.. Hoping someone has a suggestion. I have a RBwAPG-5HacT2HnD, love this thing. But yesterday morning we started getting weird outage alerts from monitoring at home, with some devices being offline. (The main kicker was the cubby lol) When I got home from work I went looking, and finally tracked it down to wlan2 being missing.. A reboot brought it back.. But 10 mins later it was gone again. Rebooted it a few more times, then added remote syslog, and went to bed. Got up this morning, and remote syslog really wasn't any use at all (I assume there's some specific prefix I should have been punting to remote syslog to catch the device going away), and now reboots aren't helping, it has to be a physical power removal and re-application.. Thankfully I have a spare (Got one on ebay at the start of the year, and had meant to set it up at the back of the house), so have just finished copying the config to it, but would love to get this one working properly again.. Was hoping it was just mini-PCIe cards or something, but alas no. Has anyone had the 5GHz radio go away on these? And fixed it? It's 4 1/2 years old, so I'm pretty sure it's out of warranty period 🤣 Thanks, DG -- Damien Gardner Jnr VK2TDG. Dip EE.
