hi
how we can guarantee bandwidth for some users or ip range.
we reserved in configuration but when other users use more bandwidth the system automatically decrease bandwidth of reserved users.
i mean we want to dedicate some bandwidth to some users but system only do it if there is some free bandwidth.
best regards

Reservation rules *should* be an "on-demand" feature. Meaning, that the reservation rule should not take away bandwidth from other traffic UNLESS there is traffic detected that matches the rule.

It sounds like you are describing almost the opposite situation. Bandwidth is being reserved and then when NON-MATCHING traffic is detected, it's cutting into the bandwidth that *should* be reserved. Am I understanding correctly?

When you observe real-time traffic for hosts (Status-->Active Hosts-->[hostname]-->Connections), are you observing expected results in the "Bandwidth Management Rule" column? Are there, perhaps, other hosts transmitting that ALSO match the reservation rule? Is it possible that, as a group, the reservation rule is applied appropriately, but when looking at an individual host you're only seeing a fraction of bandwidth specified in the reservation rule?

we have one internet interface in kerio and only NAT all hosts to it. Then we set a rule and for 2 IP host we reserved half of all bandwidth. but when other hosts are using internet those 2 reserved host only can use minimum available bandwidth not full of bandwidth that we reserved for them.
we want to dedicate half of our internet bandwidth to some host that when they want to use it take away that reserved bandwidth from other host.
is it possible in kerio control and how?
best regards

If I'm understanding correctly, I'd urge you to try something like I've done in the attached screen-shot.

Create your priority IP address group. Build a traffic rule to allow this traffic (it's probably already allowed, but you need a traffic rule to be able to capture/isolate the traffic from only those two hosts). Then build your Bandwidth reservation rule using your new Traffic Rule as the "traffic" type.

See screenshot(s). ./fa/3945/0/

i did exactly like u did. but this configuration do not guarantee bandwidth to that traffic and when other hosts use most of total bandwidth, Bdwidth of this rule goes down. and system only gives reserved bandwidth to this rule only if the other users do not use it.
it means the kerio control only reseve available bandwidth and do not guarantee and dedicate bandwidth to some rule.
ok?

To be clear, it's not a 24x7 guarantee. If 50% has been reserved for you, but your only activity at the time is retrieval of a text email, then you do not need 50% of the bandwidth and Kerio Control will not take it away from other traffic. This is what is meant by "on demand" in my initial response to you.

You need to be generating traffic. The traffic you're generating needs to be large enough that it meets or exceeds what you've defined in the rule.

If you really want to keep 50% for yourself and 50% for everyone else, you may want to add a bandwidth limitation rule just below your reservation rule and apply the limitation rule to all other users. I don't see what additional value this would add to you and it would only (unnecessarily) restrict everyone else.
