We did some performance Tests with Wireguard and man it is faster than any other VPN with much less CPU load! And for Android Phones the battery is not used more than without VPN, which is not true for all other VPNs - It makes a VPN almost transparent performance wise. Please implement!!

@sid5632: thx, changed it to your version

no, the CHR is on our own ESX in our datacenter.

robertpenz

I'm seeing on our firewalls that our test CHR is trying to connect to IP 169.254.169.254 with HTTP every few seconds (= over 250.000 connections attempts in 12h) . Google showed some old posts from 2015 where it was described as bug that will be fixed. As we're running 6.41.4, so it seems not. I did...

What about Meta-Router feature? And Spectre is not Intel only, also ARM. https://security.googleblog.com/2018/01/todays-cpu-vulnerability-what-you-need.html These vulnerabilities affect many CPUs, including those from AMD, ARM, and Intel, as well as the devices and operating systems running on them.

Hi! Is RouterOS (and if yes which versions) affected by the CVE-2017-14491, CVE-2017-14492, CVE-2017-14493, CVE-2017-14494, CVE-2017-14495, CVE-2017-14496, CVE-2017-13704 which where released by Google? https://security.googleblog.com/2017/10/behind-masq-yet-more-dns-and-dhcp.html I'm asking as I fo...

I've reported that problem in ticket 2017020822000589, and Sergejs has acknowledged a bug with handling tagged packets and they will fix it.

robertpenz

I see the same problem with 6.37.4. It seems to be a problem on interfaces which have tagged vlans. As I see the same problem on multiple routers which are not on the same subnet it can't be a damaged NIC or wrong configured client. We've also activated reverse path filtering so its not possible tha...

Hi!

What is the purpose of the mode button/switch next to the USB port as seen on this image. Could not find an answer searching.

robertpenz

With userspace I meant that there is no kernel patching needed as the mikrotik kernel is heavily modified so that would be tricky to apply. A user space program with only a few dependencies should be much easier to integrate.

Hi! I don't understand why Mikrotik keeps DSA, its insecure (yes, also the 2048bit version), and does not support RSA. Anyway yesterday OpenSSH 7.0 has been released and DSA is not longer supported. So please move to RSA and ECC now - Thx! see also: http://it.slashdot.org/story/15/08/11/2340247/open...

robertpenz

RSA would be great for yubi keys to have two factor authentication (ssh key on the yubi key)

robertpenz

Please make it possible to push certain clients from 2,4 to 5ghz if the same SSID is configured (which should the default mode on shipping). Some devices stay on 2,4 even if they support 5, and the air time in the 2,4 space is valuable.

Answer is per router: * how many peers; 10 * how many routes in routing table; /ip route print count-only 1978010 /ipv6 route print count-only 43565 * is there also OSPF,MPLS, VPLS, RIP etc running on the router; OSPF * what are the hardware specs; CCR1036-8G-2S+ * are there routing filters; yes * a...

Hi, We've implemented an OSFP ECMP setup with 5.x and for each tcp connection / flow it has been decided which route it takes. For us it seams that this has been changed with 6.x that the same dst-address (of the flow) of multiple clients stay on the same interface. Is this correct? and how can we c...

Following text http://wiki.mikrotik.com/index.php?title=Manual:License&curid=1634&diff=26596&oldid=26595 RouterOS upgrade capabilities are not limited by time, but by version, and this depends on the RouterOS license level. For example if you are running RouterOS v5, your license could r...

Is it possible that this are aggregated AS?

robertpenz

I've found AS paths with { } entries ... does someone know what that means? Here a screenshot

robertpenz

I replaced 2 Vyatta Routers with Mikrotik ones, the setup is the basis for this blog post: http://robert.penz.name/779/howto-setup ... k-routers/

robertpenz

What I want to know is, if only the administration (HTTPS, Winbox) is vulnerable, which would be not big problem as we're using dedicated management networks, or production service also external user can reach.

robertpenz

ok only 6.x gets an security update. so switch services are vulnerable? I need this to compare the the security impact against the time and money the update from 5.x costs.

robertpenz

With my routers running 6.x thats easy. But we've many 5.x still and a upgrade to 6.14 is not that fast done. So I would like to know which services/protocols are affected. If I don't use them I don't need to upgrade. Or will there be a 5.x security release.

robertpenz

Which services / protocols on the RouterOS are vulnerable?

robertpenz

Because I post in my blog not only Mikrotik stuff (in reality it is only a small part) and I want one central place for all my stuff.

robertpenz

I've written a howto on combining Suricata and RouterOs (/tool sniffer) for a SOHO setup as IDS (Intrusion detection system).

Is nobody running a Layer 3 hotspot network?

robertpenz

For authenticating users to login via ssh access onto the router or something like this you're correct. But for authentication devices for network access via 802.1x RADIUS is the only game in town. And the encryption of data is not so important there as EAP-TLS is mostly used (If security is a conce...

robertpenz

I have following setup in my lab to reproduce the problem: The Mikrotik has the Internet connection and is running a DHCP Server and Hotspot Server. A layer 3 switch which connects the clients and also provides a DHCP Relay. e.g.: Internet -- Hotspot Mikrotik - (10.0.0.0/24)- Layer3 Switch - (10.0.1...

robertpenz

What has TACACS (Terminal Access Controller Access-Control System) to do with authenticating network devices? As far as I know TACACS is only used for authenticating users that want to access the router (= the admins) .. it has nothing to do with network security or I'm mistaken?

robertpenz

Zorro: I believe you misunderstood my feature request. If you use the DHCP Server on the Mikrotik it is possible to add the MAC address of the client which got the lease to the ARP table of the router. If you now disabled ARP learning only Clients with DHCP can talk over the router and ARP spoofing ...

Does this mean 6.x have the vulnerability and 5.x don't?

+1 for the post from SwissWISP ... that and a paid support subscription are the only parts holding us back in using Mikrotiks more and in more critical areas.

robertpenz

It would be nice to buy the CCR with 2 PSUs in the first place. With the CCR you're moving into the data centers where this is standard.

robertpenz

Yeah, I would also use only one area for this small setup. Remove the complexity!! >500 routers in one area is no problem today ... Use areas to separate devices with bad ospf implementations from the rest. E.g. loadbalancers or mainframes Or for security reasons ( you want all traffic over some spe...

Why not make 2 ipip tunnels and run ospf over it? I'm running ipsec encrypted ipip tunnels with ospf for a long time without problems .

Mode is very similar to LACP except that it...

robertpenz

I believe the x2 is a dual core machine, which does not support metarouter.

robertpenz

But often you need something on such a "big device" the mikrotik os does not have, like a real radius server (freeradius) and than a openwrt would be nice. If 60mb more flash would make it 5-10 euro more expensive I believe nobody would mind and it would really open some use cases.

robertpenz

but the new 1100AH has also only 40mb and there it is supported (which is good btw as multiple routing instances is state of the art for better switches/routers)

robertpenz

but a router with virtualisation support, which can't be really used with 40mb

robertpenz

I formated it and than I got the status "ready" otherwise it would be not ready. I also did a check-drive. But I'll try an other microsd card, maybe it is incompatible.

Hi!

I've connected the 1100AH to the normal power (230V) and connected Eth13 to a POE injector. If I removed one of the two power connections the Mikrotik kept running. Has this setup any bad side effects?

Is there a possibility to monitor if one of the 2 "power supplies" goes down?

robertpenz

We've the same problem, just bought four 1100AH with the explicit purpose to use them with MetaRouter, as MetaRouter is not stable on e.g 450G. We really need a fast feedback/solution as otherwise we'll send them back as not working, which we can't do if we keep it longer than for a few days. We bou...
