MikroTik Hairpin NAT With Dynamic WAN IP Tutorial Update

I’ve had my YouTube video out there for a while now (link) and whilst it does get a fair amount of traffic I have always wanted to follow it up with something written as well.

I’ve now just added in a full written tutorial of how to achieve this by using my easy to use drag and drop .rsc file. Head over to the MikroTik section to see more or for a direct link go here

MikroTik WAP60G Wireless Wire – The Best You’ll Never Use!

wirelesswire

OK so maybe I was a little harsh in the title, but to be honest. It’s quite true for the UK right now.

MikroTiks wireless wire truly is a groundbreaking product, Gigabit full duplex link over wireless at a total retail cost of less than £200 but if something sounds to good to be true, it usually is. The form factor of these units following the WAP build is great, small, versatile and outdoor grade, they feel so well made with a good weight to them. The box comes presented well and they have a nearly premium feel when you are opening the package (something which normally eludes even the expensive MikroTik products). Out of the box they follow MikroTiks normal IP convention of being on 192.168.88.0/24 space and are addressed and fully secured from the off, you can literally connect them and start passing traffic over them. So I did.

Performance was just as good as expected, with the units in very close proximity (probably a little too close) they were quite capable of maintaining a +800Mb speed test although that was using the built in bandwidth tester which is quite notorious for not being as efficient as it could be. Single duplex tests were slightly better as expected and when the connection was limited to “only” 500Mb either direction latency was measured at <1ms. At full tilt the latency did get a little wobbly but again I’m more along the lines of thinking this was the CPU’s in the devices that the actual link limitations.

So why won’t we be using this?

Unfortunately for our country whilst the use of the 60Ghz frequencies mentioned is license exempt, there are stipulations you need to adhere to, this one falls over in that whilst MikroTik haven’t officially released the specs, it is speculated the antenna gain in them is around 13dB which falls short of OFCOMs guideline stating that you need to use a minimum of 30dB to legally use the 60Ghz spectrum outdoors (page 2 if you’re interested). For the time being this means that this amazing wireless wire product is indoor use only.

There is a company though in Poland who are currently developing some larger antenna for them http://siec.multimediahd.pl/

So whilst the Gigabit full duplex low latency low price link is something we certainly want to see more of, you won’t be seeing one mounted externally anywhere near you any time soon (well not legally anyway).

Exciting news for CHR in RouterOS 6.42RC

CHR has been the best way to deploy a virtual version of MikroTik’s RouterOS for a long time now. The dedicated virtual version includes some additional drivers and whatnot to make sure that it plays nicely with the popular virtualisation programs out there, Xen and VMWare being the 2 big ones everybody tends to go for.

Whilst some instances of CHR can now be found even on Amazon AWS there was still this niggle for those running Xen and VMWare that bugged them, traditionally on a “normal” VM you install it and then run the relevant “additional tools” installation so that the host cna pull out some information from the guest and also certainly in VMWare’s case, soft shut down or reboot the machine rather than a hard power off (we all know how RouterOS likes to log that as a fault!)

With 6.42RC things have changed though! Both xen-tools and open-vm-tools can now be found within the package and to ensure this wasn’t a joke I quickly span up a machine from the supplied OVA file and there it was feeding it’s name back to me as well as being able to soft reboot it. Good times!

A word of caution though, I personally would never recommend anyone use an RC for anything other than testing. New features introduce new bugs that need to be ironed out, whilst the wait for 6.41 to go to bugfix had started, now the wait is on for 6.42 to go to current!

you can download the latest version and see all the change logs openly on the Mikrotik website just here.

MikroTik Router OS 6.41

MikroTik have released their version 6.41 of the current build. Whilst there are some new features the most obvious one now is the removal of the master-slave relationship ability to allow hardware switching. MikroTik have done this in a bid to simplify the configuration meaning that now you can use the bridge functionality.

Previously bridging was all done through the CPU so switching on lower end hardware meant that you may not always get full speeds and often ended up with a 100% CPU utilization for a simple file transfer.

MikroTik have now made it so that you can add single, multiple or all ports into a bridge with a check box available to take advantage of the “hardware offload” function. Again, whilst not technically a new feature for the series, it is a redesigned way of achieving hardware switching. The result is a brilliantly clean implementation which resulted in the following from my testing on an older gigabit router.
