Prioritizing Bandwidth to IP Range

a_thiha · Mar 5, 2016, 10:18 AM

Hello.

Could you guys please give me some advice on how to configure prioritize limitation by using limiter or other QoS tool.

For instance, I want a range of IP to have 8mbps guaranteed speed all the time on my 10mbps Internet. If this IP range is not using any bandwidth, the rest may consume all the bandwidth. But this specific IP range will always have the exact amount of bandwidth no matter what. It is simple as that. ;)

I would be very appreciated if you could suggest me or lead me to a way to work this out.
Thanks

You could use aliases to create a list of hosts, then create a queue to prioritize 8Mbit to them. One queue for upload, another for download.

Check out the wiki for details. https://doc.pfsense.org/index.php/Traffic_Shaping_Guide

First off, thanks a lot for your quick reply. I will try it out for sure. The most confusing thing is that which part of the steps really did for prioritizing or giving a guaranteed speed for my special IP range. I hope I am not asking too much here. :)

Thanks again.

Hi again.. I tried as you suggested and it is not working as I expected. Maybe it is because of my ignorance. Please check out my settings below.

1. I created an aliases for my Special IP range.
2. Then went to Firewall > Traffic Shaper > Limiter to create a 8MB/s Download pipe and queue.
3. Went to Firewall > Rules > Lan to create a rule to allow access to my Special IP range. Then in advance, In/Out - Admin_UP_Queue / Admin_DL_Queue.

Then I tested my download and it seemed the rest of the IP still affecting my 8mbps guaranteed speed. I don't know why.. :/

for the info: this is my download pipe and queue in Limiter..

Name : Admin_DL
Bandwidth : 8 Mbit/s
Schedule : none
Mask : none

I added a new queue

Name : Admin_DL_Queue
Mask : Destination addresses

The same settings go to UPLOAD pipe but different speed.

that's what I have done…
Please light me up if I am missing something here.

Thanks.....

Using both queues & limiters implies you have not done your research. You only need one of the two.

We are willing to help, but you need to show that you have put some effort into learning how to solve the problem yourself.

Limiters don't guarantee bandwidth, they limit bandwidth. If you create a limiter that limits your special subnet's bandwidth to 8Mb/s, that doesn't mean they'll always get 8Mb/s, just that they can never exceed it. You also need to place limits on the complement of that subnet.

I personally prefer to use HFSC, which defaults to specifying minimums instead of maximums, although you can also do maximums.

I'll admit that I have a limited knowledge when it comes to dealing with this part of Pfsense. Still it doesn't mean I am the best in other parts.. ;D

I will surely do my research since I got the right way to achieve it and thanks to you guys. I just didn't want myself going on wrong way. ;D

Now it seems like HFSC is the best practice to meet my needs. I am sorry if I made my problems yours. :-[

Thanks for the suggestion Mr.Harvy66. Really appreciate it. I will work on HFSC now. 8)
