Re: Bondig WIFI links 60G and 5G

I wouldn't use LACP with links of different characteristics. It can be a nightmare.

It's better to configure them in an active/passive fashion with the 5G link acting as a backup and forwarding packets only if the 60G link fails.

Re: v6.44rc [testing] is released!

Using the stable releases (6.43.12 included) I can't establish a link. With 6.44 betas and rc it works, it just needs to set the interface to 1 Gbps
These fixes will be included in upcoming v6.44.

So far I'm checking all the betas and rcs to make sure it still works.

Re: 6.9 released!

I think there's some bug in the wireless subsystem, introduced in version 6.7. I have two Omnitiks used to establish a link across a street. Nothing fancy, it works solid with NV2, CCR between 80-100% depending on when I open a window (both units are indoors, placed close to the windows). Until I up...

Re: Reverse Path Filtering - Interface?

Unfortunately not, which makes the feature useless and even dangerous except for the most trivial settings.

Re: Feature request: BGP flowspec (RFC5575)

Right now not many transit providers support it. From the Mikrotik side, the priority would be to implement the BGP exchange, even if RouterOS doesn't have the mechanisms in place to actually apply the rules, but at least enabling the RouterOS to send BGP flowspec advertisements to the transit provi...

Feature request: BGP flowspec (RFC5575)

Are you planning to implement this? For unfamiliar readers, roughly speaking, it uses BGP to distribute filter specifications. It's very useful in DDoS attacks, allowing you to send "firewall rules" (matching on source and destination addresses, protocols, ports, etc) to your BGP peers/transits, so ...

Re: As we would like to evolve the wireless

You mean an attenuator on the 5Ghz frequency (the ones where you work normally) or attenuation larger or smaller 5Ghz frequency (or the specified range) I believe that an attenuator lowers the input power and also output when used on the range of operating frequencies... you give an example An atte...

Re: As we would like to evolve the wireless

A very important feature would be programmable hardware attenuation for the receiver part. That would improve the performance in high interference places. You would be able to use a higher transmission power, so that your signal would stay above the interference, at the same time avoiding the receiv...

Re: How to measure traffic to an ASN?

Hi,
I'm trying to get a peering agreement with a local Content provider, but I need to measure the traffic from my ASN to their ASN. What method or program do you use to measure ASN to ASN traffic?
For that purpose (and many others!) Netflow is your friend.

Try nfsen (nfsen.sourceforge.net).

Re: Unicast Reverse Path Forwarding

I've been trying it on 6.1 and I have found some problems: 1) If I enable it, it seems it isn't actually enforced until I reboot the router. 2) This is not the best way to implement it. It should be controlled for each interface, instead of being an all or nothing parameter. In a provider network yo...

Re: v6rc14 released

it's actually 'upload' of a 'target', i.e. traffic received on the interface :) does not feel clear nor simple. :( It is "Target upload" not "router upload". Therefore, these options are from perspective of the target. If you want to limit your users's upload capability, set "target upload". I'm st...

In case "target" is an interface, which direction is considered "upload" and which one is considered "download"? I would rather use...

There's a regression problem. On 5.25 I can add a simple queue and bind it to an interface. Example: [admin@OmniTik-casa] /queue simple> add name=queue-guest max-limit=512K/128K interface=ether2-master-local This doesn't work on 6.0rc14. I can't add the "interface" clause to a simple queue.

Regarding logging, I really miss a detailed logging of router advertisement/withdrawals for the routing protocols in debug mode. Not just state transitions.

Re: Wireless WDS setup, cannot see LAN network ..

I don't understand why you are using WDS. If they are connected to the same wired network, just set the same SSID and, of course, the same authentication parameters. The clients will connect to the strongest signal.

Hi :) I'm a newbie with this equipment, for now I am playing with a pair of Omnitiks. There's a useful feature I *really* miss: a receiver side attenuator. It can be very useful to battle high noise. It allows you to increase the output power of the transmitter to achieve a higher S/N ratio, while p...
