Hi all! We have some certification classes coming up in Brisbane during May 2022 and, as usual, we like to offer one or more 'sponsored' places at one or more of those training events to support tech communities, education and charity type organisations. Applicable classes are MTCRE (Routing) and MTCINE (Internetworking) - eligible candidates must be MTCNA certified, or significant and demonstrable background experience with MikroTik products, and should have some association with one of the mentioned organisation types above, or particular personal circumstances that may warrant sponsorship. Anyone interested in exploring these opportunities further, please get in touch with us direct via training(a)duxtel.com <mailto:training@duxtel.com> , or just reply direct to myself : ) Cheers! Mike Everest. ------------------------------------------------------------------------------------ Why Choose DuxTel for all your MikroTik needs? 10 good reasons: http://duxtel.com/why_duxtel ------------------------------------------------------------------------------------ Follow our tweets for news and updates: http://twitter.com/duxtel

Isolated VLAN for Android 6.0 device
by Ben Williams 11 Apr '22

11 Apr '22

Hi folks, I've had a new air conditioning controller installed, an Airtouch 4. Turns out it's just a little tablet running Android 6.0 - truly an example of the old phrase, "the S in IOT stands for Security" :D It connects to wifi and offers remote control (both on the local network and over the internet). So I'm thinking what I want to do is isolate it on its own vlan that has no outgoing access to the rest of my network, but still has external internet access and inbound access from the LAN so the phone apps still work to control it. I've got a Mikrotik 951G-2HnD running RouterOS 6.49.2, with LAN (NBN HFC) hanging off port 1, a single Unifi wireless AP hanging off port 2 (the 951G's wireless is turned off), and other stuff off ports 3, 4, & 5 (other switches, a NAS, etc). It's all on a single network; the 951G runs DHCP for 10.1.1.0/24 on the bridge interface, there's a basic firewall configured, and IPv6 is enabled and running. So I assume what I need to do is some kind of vlan config to separate traffic, and some routing and firewall config, but I really am not sure how to achieve it. Maybe something like: - Create 2 new vlans, one for the unrestricted devices and one that I'll use for isolated devices - Add both vlans to all ports? The Unifi AP can do vlan tagging by the looks, so I could create a seperate wireless network for the restricted vlan as well. (Or maybe the easier way would be to turn the 951G's wireless back on purely for this restricted access, take the Unifi AP out of the picture) - Create a new DHCP range for the restricted vlan (can I decide which dhcp range will respond based on the vlan tag?) - Create a new firewall config to prevent the restricted vlan from communicating to the unrestricted vlan? - Routing config of some kind? I'm not much of a networker, so any help would be much appreciated. - Ben

Odd IMAP failures, seems to be network
by Karl Auer 09 Apr '22

09 Apr '22

I run a Mikrotik router as my home router, have done for years. I personally have never had an issue with it. The current one is an hAP ac^3 running 6.47.10 with plenty of free RAM and disk space and virtually zero CPU usage. However one of my "users", running Thunderbird on Windows, has an ongoing problem using IMAP. When she sends an email, the email is not saved to the (IMAP) "Sent" folder. If she saves a draft, it fails to save to the (IMAP) "Drafts" folder. In both cases the failure comes after a long wait, indicating IMHO a network problem. This does not happen all the time, but often enough (well more than half the time) to be extremely frustrating. We can discern no commonality between the affected messages - large, small, addressees, attachments etc. Sometimes if she disconnects from the network and then reconnects, the message will work the second time around, but IMHO this is just blind luck. The thing is, this does NOT happen when she is using the same computer outside our home - on a public network, her phone's hotspot or whatever. Only at home. I have excluded wifi as the problem; she gets the same issue on a wired connection. I have set up my own IMAP connection (though not as yet with Thunderbird) and cannot replicate the problem. She and I use the same local network, the same email provider and the same connectivity provider (ADSL from iiNet). The link is slow (about 14/0.4), but has been dependable and as I say, I do not have any problem other than with speed. This has been going on for probably about two years now, getting steadily worse, to the point where she now leaves the house to work (which is a big deal, as it's a 40-minute round trip to a suitable location). I'm at a bit of a loss as to what it might be, and am asking here to see if anyone has a router-related clue. Or any ideas as to how I might go about troubleshooting this.
