if you are using RJ-45 Interfaces, or sfp copper dac cables, consider the posibility of some electrical problem at the site Cat 5e cables in RJ-45 interfaces. Never had any issue like this before, having CCR, CRS, CSS and a lot of other devices in this rack. I will test it out of the rack anyway. a...

We just ordered a brand new CCR2116-12G-4S+ to replace a CCR1016 but when getting it up in the rack yesterday I came across with all ports from ether1 to ether12 flapping after I connect more than 1 cable to it. When there is only 1 cable connected this doesn't happen. Initially tought it was someth...

Is the simple action=same rule you've mentioned above the only one in chain srcnat of /ip firewall nat ? Are there any rules in /ip firewall raw ? NAT is a functionality of connection tracking, so packets matching an action=notrack rule in /ip firewall raw cannot be NATed at all. Also the "sim...

My understanding is as follow: Netmap - Maps IPs 1:1, so must be 1000 IPs to 1000IPs, i.e. a /22 to a /22 Same - You might have 1000 IPs mapping to 255 IPs, so the NAT will try and use the same NAT IP map per src/dst address pair, if src and or dst is different, it might use another IP to map/NAT t...

tsouzar

Have you tried reading the Mikrotik wiki to understand how Same and Netmap works and what the difference is? Sure. same - gives a particular client the same source/destination IP address from supplied range for each connection. This is most frequently used for services that expect the same client a...

Hello, I know firewall NAT action NETMAP is an 1:1 address mapping based on to-addresses netmask, I expected action SAME would be more flexible, but seems like it doesn't or I am facing a bug or issue here. I want to NAT an address list with ~1k addresses to a /22 public IP subnet for just outgoing ...

Hello. I got CHR running fine on a Proxmox host except I can't get it to recognize a second disk I pretend to use for The Dude storage. I did install it from OVA file (extracted it then imported OVF) and Proxmox's storage is a ZFS pool, if that makes any difference. I tried both VirtIO SCSI and Virt...

WebFig is slow to load informations, doesn't have same multi-window behavior as Winbox, is full of validation bugs, is ugly, is boring with session timeout limit and isn't responsive to mobile devices. MikroTik should replace it with a basic web GUI for newbies, just like TP-Link or D-Link ones, bec...

tsouzar

Posted in another thread, figured I would copy paste. The issue isn't with Mikrotik's programming capabilities. Unfortunately they are choosing to be tight lipped as to why this feature is absent. Qualcomm realized how important this feature was and started limiting it's support in their chipsets t...

Just stop calling other people idiots and do not create new threads for topics that are already discussed elsewhere. I thought you might understand my message. :wink: I got a reply from MikroTik in a ticket I open regarding this question. They said are working to improve performance of 802.11ac rad...

tsouzar

People who make the best devices you can buy (and you do that) are idiots while you are not an idiot when you are paying them...

Are you X because you buy things from somebody that is X, being X an attribute? Not a good logic.
Let's keep the topic within original subject.

tsouzar

So you are not an idiot because you are smarter and not buying their products at all,right? If so, why do you care? If not so, don't you mind to give your money to such idiots? I would. Yes, I mind to give money to these idiots, and that is the reason why I think they should at least give some atte...

tsouzar

I do not believe that they don't care and for sure not because you call them idiots. Please, think before you name someone like this. The truth is that official statement to this topic is still missing. Yes, they (or the person that made the choice to launch 802.11ac radios without first getting Ro...

tsouzar

It really is. If you want to urge mikrotik, create a ticket at them by sending email to support. This is user forum only. So, what is the purpose of this subforum? It says in description: "BETA Testing and Feature Suggestions for the next RouterOS release (ROS v7)" Anyway, even through I ...

tsouzar

Come on, MikroTik, this is URGENT! Stop wasting time adding new non-important features and fix Spectral Scan now! Your 802.11ac devices are useless in heavy noise environments until this is solved. 3 years and nothing yet... Or maybe you should send your engineers to spend some hours picking clean c...

tsouzar

This was said many times here and there is also a dedicated thread for this. Cool. I saw that topic once, but forgot about it. Anyway, looks like MikroTik does not care. They continue wasting time with less important things. I created this topic to remind MikroTik that this is URGENT, not just a co...

tsouzar

I think MikroTik can't see the urgency of fixing Spectral History and Spectral Scan (The Dude) in 802.11ac devices. I'll make it clear: your 802.11ac radios are USELESS without it! It's stupid to imagine MikroTik think somebody can use their 802.11ac devices without the ability to analyse the RF spe...

Why are the power supplies without fans? This is the reason most power supplies die in CCR series...

Great question. Waiting for Mikrotik reply on this.

Dear, I have a RB750GL in one of our POPs and it routes and authenticates about to 40 clients using Hotspot. We are experiencing a big delay when accessing and browsing through the web management interface of our Rocket M5 that acts as PTMP AP at that location. This happens since we replaced previou...

One full bgp table require 500MB. So, 2GB are sufficient. Yep, that was just an example of what I know to be huge RAM consumer in RouterOS. I'm more interested in knowing which are other RouterOS' features that may spend much RAM so justify 2GB on a router. Or maybe MikroTik was only looking at BGP...

tsouzar

This seems to be a problem of your downstream client, not yours. It needs to do proper traffic engineering in order to traffic be rightly balanced over two upstreams (you and the other). 2nd option from @zagziggy's answer is easier way to achieve incoming traffic balancing. I would just add that usu...

tsouzar

Guys, I was asking myself if CCRs need that big amount RAM they come with for anything more than full BGP feeds. Do they? Is there anything else that would take so much RAM? I've heard about queues being a big RAM consumer (maybe for buffers). Is that right? And what about conntrack, does it need mu...

tsouzar

I made a mistake (and Wiki is wrong). It's on /system resource irq rps.
There's no need for installing extra package. You must configure it from terminal, it's not available on Winbox.

tsouzar

Microsoft makes use of own protocol named BITS, that is based on HTTP. The whole traffic is encrypted (SSL/TLS) and used ports vary a lot.

Summary: it works like torrent and thus is impossible to be detected by firewall and blocked/limited.

tsouzar

We experienced the similar issues while testing simple queues. This was resolved by turning on rps on the Ethernet interface to allow it to use the multiple cpu's. This may be the bottleneck you are experiencing. Hi Aron, could u please point me right to turning on the rps, where exactly this optio...

I had this problem on my home's RB951Ui after changing network netmask on interface and DHCP server. I could't solve it until when rebooted my RB and everything came to work properly. What a crappy bug, MikroTik!

tsouzar

Dears, I currently have one RB/CCR in each of my access networks (PoPs) and they work as DHCP Relay of a central CCR that runs DHCP Server. Now I need to run a script each time DHCP leases or releases an IP address. It would be easy if I didn't have the need for use DHCP relay's IP address within th...

+1

That would be great.

tsouzar

Thanks everybody for your answers. Can't you use a RB 2011 with more powerful external antennas ? Granted this knocks the cost up quite a bit . No. RB2011 is so much expensive and waste of resources for most of ISP's customers. Why? because sensitivity is the "real thing", and compared to ...

tsouzar

People, since RB751, MikroTik haven't launched any new SOHO RB with external antenna connector. Why? Those 2.5dBi internal antennas that comes with RB951, hAP, mAP are very poor and not sufficient for all scenarios (I guess MikroTik engineers doesn't know most of houses' internal walls around the wo...

Feature request for the next v6 release Feature: Instead of giving current options of IP packet fields combinations, add 4 individual options: src-port, src-address, dst-port, dst-address, like some other routing systems do. This would allow us to have more custom and efficient load balancing rules...

Winbox v3.0rc2 connected to RB133 running RouterOS 5.26 has the following bug on viewing any wireless interface: http://i.imgur.com/KzcWQFV.jpg The problem doesn't occur with RouterOS 6.25. Other bug I found is with routing filters. Winbox 2 shows them rightly, but v3.0rc2 is buggy: http://i.imgur.c...

Hello. I have a /40 IPv6 address block at some MikroTik router (R1). I need to assign a /48 to another MikroTik router (R2) that is not directly connected and only way to do it is using tunnels. My question is: what is the difference of making a 6to4 tunnel between R1 and R2 and making an EoIP/IPIP/...

tsouzar

I wonder why Mikrotik wastes time for making such unuseful things instead taking care of correcting the bugs in ROS. Can't they work on more than one thing at once? I enjoyed new forum look. Only problems is lack of contrast, color sheme which doesn't look like MikroTik.com (where is red and green?...

tsouzar

Thank you all.

I was thinking only on CPU model and forgot amount of RAM.
So, it's safe to upgrade archaic RB133 to v6.

tsouzar

Hello. As title says, my question is: why is RB133 supported by RouterOS v6 while RB133C isn't? They have same hardware, except RB133C have somethings missing. mikrotik.com/download says: "RB111, RB112, RB133C, RB150 devices are not supported in v6, please use v5.". Is this right? Can I up...

Oh? That's different from what I've seen in projects that "start off" as C++ projects. But if you can pull off what you say there, that's great :D . #ifdef __cplusplus //C++ way of doing something, e.g.: int* allocate_integer(int* value, int bytes) { //do it using smart pointers (C++ only...

tsouzar

Better than nothing I guess, but that would still require the user to have a C++ compiler alongside their C one :? . Not right. It will require just a C compiler. In other words, same code can be compiled as C or C++. C compiler will read only the code I put in #if statements that match C language....

tsouzar

If you want to make a RouterOS API client useful beyond C++, I'd suggest you make a new C client, and wrap the C++ code around that . C way of doing things is hard to accomplish and obsolete. C++ does better memory spaces and pointers managing, etc. Maybe I use #if's to add C compatible implementat...

tsouzar

Thanks for your answer. Yes. It will work as specified, i.e. normally. Is there any need to allocate a memory space with encoded length size, to send a message with exact byte amount? This question comes from the use of chr() in example code to send 1 byte messages, instead of 4 bytes with 3 of them...

tsouzar

Hello folks. I'm developing my own C++ client for MikroTik RouterOS API which I will use in some projects. (I don't liked that existing one) I've a question: Example client provided by MikroTik on Wiki page sends each byte of encoded length at a time to the router. Is this really need? Can't I send ...

Hello. I really liked when RB951G-2HnD and RB951Ui-2HnD had been launched. They're powerful and great cost RBs, with a such amazing CPU and 128MB RAM, wow, wonderful. However, for having wireless, they came to be a bit expensive to be used in place of RB750 series. RB750 and its variations are very ...

Wow, really. I forgot this detail, rextended. You can call me dumb.
Thank you rexended and Rudios.

So, the wrong src address problem was due this general masquerade... problem resolved. Thanks!

the problem is simple: you masquerade all... all the traffic passing trougth the router appear from 203.0.113.x the masquerade MUST be used only from one pool of not public IP address as src-address to out on one wan interface.
