Limit the maximum rates for sending ICMP packets whose type matches icmp-rate-mask to specific targets. Mask made of ICMP types for which rates are being limited. More info in linux man pages. Resets all configuration parameters to defaults according to RFC for routers. Disables enables source validation.

Each incoming packet is tested against the FIB and if the interface is not the best reverse path the packet check will fail. By default failed packets are discarded. Each incoming packet's source address is also tested against the FIB and if the source address is not reachable via any interface the packet check will fail.

If using asymmetric routing or other complicated routing or VRRP, then loose mode is recommended. Send out syncookies when the syn backlog queue of a socket overflows. This is to prevent against the common 'SYN flood attack'. SMTP relayingvisible not by you, but your clients and relays, contacting you.

Hotspot, apply different limits and different traffic priorities

Disable or enable Linux route cache. Note that by disabling route cache, it will also disable fast path.Burst is a feature that allows to satisfy queue requirement for additional bandwidth even if required rate is bigger that MIR max-limit for a limited period of time.

Burst can occur only if average-rate of the queue for the last burst-time seconds is smaller that burst-threshold. Burst will stop if average-rate of the queue for the last burst-time seconds is bigger or equal to burst-threshold. Burst mechanism is simple - if burst is allowed max-limit value is replaced by burst-limit value. When burst is disallowed max-limit value remains unchanged. Client will try to download two 4MB 32Mb blocks of data, first download will start at zero seconds, second download will start at 17th second.

Traffic was unused for last minute. As we can see as soon as client requested bandwidth it was able to get 4Mpbs burst for 6 seconds. As soon as burst runs out rest of the data will be downloaded with 2Mbps. This way block of data was downloaded in 9 seconds - without burst it would take 16 seconds. Burst have 7 seconds to recharge before next download will start.

Note that burst is still disallowed when download started and it kicks in only afterwards - in the middle of download.

So with this example we proved that burst may happen in the middle of download. If we decrease burst-time to 8 seconds - we are able to see that in this case bursts are only at the beginning of downloads. Jump to: navigationsearch.

Featured on Meta.The attributes received from RADIUS server override the ones set in the default profile, but if some parameters are not received they are taken from the respective default profile.

Note: The order of added items in this list is significant. Note: Make sure the specified certificate is trusted.


For this purpose DM Disconnect-Messages are used. Disconnect messages cause a user session to be terminated immediately. This dictionary is the minimal dictionary, which is enough to support all features of MikroTik RouterOS. Note: it may conflict with the default configuration files of RADIUS server, which have references to the Attributes, absent in this dictionary.

Manual:IP/DHCP Server

Please correct the configuration files, not the dictionary, as no other Attributes are supported by MikroTik RouterOS. Note: the received attributes override the default ones set in the default profilebut if an attribute is not received from RADIUS server, the default one is to be used. Rate-Limit takes precedence over all other ways to specify data rate for the client.

Ascend data rate attributes are considered second; and WISPr attributes takes the last precedence. Additionally to the accounting start request, the following messages will contain the following attributes:. Note that it is not possible to change IP address, pool or routes that way - for such changes a user must be disconnected first.

Note: FreeRadius already has these attributes predefined. If you are using other radius server then use table below to create dictionary file. Jump to: navigationsearch. Categories : Manual AAA.

This page was last edited on 3 Januaryat Explicitly stated realm user domainso the users do not have to provide proper ISP domain name in user name.HTB allows to create hierarchical queue structure and determine relations between queues.

In RouterOS, these hierarchical structures can be attached at two different places, packet flow diagram illustrate both Input and Postrouting chains. Rate limiting is used to control the rate of traffic flow sent or received on a network interface. Traffic which rate that is less than or equal to the specified rate is sent, whereas traffic that exceeds the rate is dropped or delayed. As you can see in the first case all traffic exceeds a specific rate and is dropped.

In another case, traffic exceeds a specific rate and is delayed in a queue and transmitted later when it is possible, but note that the packet can be delayed only until the queue is not full. If there is no more space in the queue buffer, packets are dropped. You can also use simple queues to build advanced QoS applications. They have useful integrated features:. Simple queues have a strict order - each packet must go through every queue until it reaches one queue which conditions fit packet parameters or until the end of the queues list is reached.

In case of queues, a packet for the last queue will need to proceed through queues before it will reach the destination. Assume we have network topology like Figure 8. Add a simple queue rule, which will limit the download traffic to kbps and upload to kbps for the network The max-limit parameter cuts down the maximum available bandwidth.

The target allows defining the source IP addresses to which the queue rule will be applied. Note: Since RouterOS v6 these settings are combined in the option target where you can specify either of the above. Target is to be viewed from perspective of the target.

If you want to limit your users' upload capability, set "target upload". Each of these two properties can be used to determine which direction is target upload and which is download.

Be careful to configure both of these options for the same queue - in case they will point to opposite directions queue will not work. If neither value of target nor of interface is specified, the queue will not be able to make the difference between upload and download and will limit all traffic twice. Queue tree creates only one directional queue in one of the HTBs. It is also the only way how to add queue on the separate interface.

This way it is possible to ease mangle configuration - you don't need separate marks for download and upload - only upload will get to Public interface and only download will get to Private interface. Read more about HTB and see configuration examples. This sub-menu lists by default created queue types and allow to add new user-specific ones. Note: Starting from v5. Usually at least packets can be queued for transmit in transmit descriptor ring buffer.

Transmit descriptor ring buffer size and the amount of packets that can be queued in it varies for different types of ethernet MACs. By having one software queue for each hardware queue there might be less time spent for synchronizing access to them.

Note: having possibility to set only-hardware-queue requires support in ethernet driver so it is available only for some ethernet interfaces mostly found on RBs. Queue kinds or Queuing scheduling algorithms describe which packet will be transmitted next in line. RouterOS supports several queuing algorithms:. Every packet that cannot be enqueued if the queue is fullis dropped. Large queue sizes can increase latency, but utilize channel better. This queue is beneficial on SMP systems with ethernet interfaces that have support for multiple transmit queues and have a linux driver support for multiple transmit queues.

Random Early Drop is a queuing mechanism which tries to avoid network congestion by controlling the average queue size. The average queue size is compared to two thresholds: a minimum min th and maximum max th threshold. If average queue size avg q is less than the minimum threshold, no packets are dropped.How to configure user group to apply user limitation was discussed in my previous article.

A user profile is nothing but a user who has no entry in radcheck and radreply table but is a member of one or more groups to hold reply attributes. Assigning group to a profile is done with radusergroup table.

User-Profile internal AVP is used to assign a profile to a user with radcheck table. So, a complete profile configuration is done by the following steps.

Cheetah ne apni beti ko nanga karke choda

As we will create three user profiles, we have to create three groups also. Our proposed groups name and its check and reply attributes are summarized with the following tables. The radgroupcheck table contains group check AVPs. The following steps will show how to insert check AVP in the radgroupcheck table. These entries ensure that group reply only applicable for the PPP request.

After inserting group checking, we will now insert group reply AVP in the radgroupreply table. The following steps will show how to insert reply AVPs in the radgroupreply table. Here, Mikrotik-Rate-Limit AVP indicates that k group user will get k upload and k download speed, 1M burst upload and 1M burst download, burst threshold upload k and download k and burst time is 40s for both upload and download.

Similarly, issue the following command to apply bandwidth limit for 1M group user. Group reply attributes are inserted successfully.

Now we will assign our desired user profile to group. After creating groups, it is time to assign group to user. The radusergroup table contains user to group mapping. So, we need to insert entry in radusergroup table to map our profile and group. The following steps will show how to map profile and group in radusergroup table.

After creating user profile, we can create as many users as we want and assign their profile with User-Profile control attribute for applying user limitation. The radcheck table contains user check attribute. So, to create users, we have to insert username and password as well as other user check attribute in radcheck table. In this article, we will create three users bob, alice and tom and assign their profile with radcheck table. The following steps will show how to insert user check attribute in radcheck table.

Now we will check these users login and reply attributes with radtest program. We will now test our user profile configuration with radtest program. So, issue the following command to login with bob user and check his reply attribute. If everything is OK, the radtest program will show the abobe output. Similarly, you can test alice and tom user with radtest program and can check user reply attributes.

I hope it will reduce your any confusion. However, if you face any confusion, feel free to discuss in comment or contact with me from Contact page. Your name can also be listed here.Note: In version 4, profiles are used for user limiting. User actions can be limited in several dimensions:. Time can be managed in two ways: user's uptime-limit field and credit 's time field.

Uptime limit is maximum time amount a user is allowed to be active to have active sessions. See the example below. Used-uptime for a user is sum of durations of all sessions this user has. Used-uptime can not exceed uptime-limit. Subscriber can define available credit vouchers. User can buy those vouchers, customers can assign available credits to users.

User credits are valid specific time. This means, when a credit is started, it must be used within a time specified. User has fields download-limit and upload-limit. To specify unlimited amount, leave blank the proper field. Limits are specified in bytes. User has field rate-limit. This field is available straight in the console, but is divided in several fields in web-interface, to ease the input process. Jump to: navigationsearch. Navigation menu Personal tools Log in.
