Traffic shaper changes [90% completed, please send money to complete bounty]

matremblay

Hello, I have gone over this thread quickly and would like to know more about the shaper itself.. I'll explain my needs first

I have been using pfsense for a while but the results are not what I expect .. yet

I manage two buildings, student housing, which means alot of p2p and well the service suffers alot from it, it's been very difficult to keep people happy for a few years now, either we restrict too much or we get bad performance.

Here's the setup:

building one, 250 users, 10mbit fiber over ethernet connection, pfsense gateway/server/router , no other shaping than pfsense
building two, 170 users, 10mbit fiber over ethernet connection, windows server gateway/router + linux server, quota per month/throttling down system (over 10gb users are put in a queue for the remainder of the month)

building one has actually better performance (ironically) than building two, because building two has a bunch of computer tech students that do more damage than the fashion design majority in building one.

I need something to manage bandwidth, in both buildings, we can't upgrade to better service it's expensive enough already. I have tried to make something myself under freebsd with dummynet last year but I lack the experience and mostly the time, network and computer stuff is like 5% of my job.

If this project (and please be honest about it) can really help my situation I would be willing to contribute 500$ per building ( I would introduce the system in building one first)

I am looking at traffic of roughly 1TB/week from these 10mbit links
There is no voip, no captive portal, no domain accounts, just plug and play free internet sharing from the wall in each room. Each time we restrict ports etc it complains, and let's face it p2p apps use ANY port. Sometimes when there is too much traffic some users can't even have internet at all and complain. If I can't find a solution with software like this I'm going to have to buy hardware for it, which means even more money with unknown results.

We want to allow fast reliable access to Web, email, IM and that's about it. The rest they can have, but I wish it would be so slow they would not care using it

So let me know if you think it would work

Thanks in advance

Can you try a snapshot of 2.0 and use the limiter?
Actually it is dummynet just used with pf.
You might want just a simple layer of dummynet, 2 limiters(pipe) or queues(childs) in dummynet with appropriate src/dst mask which will share the bandiwdth according to online users and you can use ALTQ to prioritize types of traffic like HTTP ACKs better than normal HTTP traffic etc….

We are getting there on protocols shaping(l7 detection) but not finished.

If it is satisfies you in 2.0 i can merge it back on the 1.2.1 build, based on your contribution, i will make available after the 1.2.1 release of pfSense.

I did not notice it was possible to download a 2.0. I will try to install it, since its not a full release I must first check to see if the network is functional with it for a little while, I really can't afford alot of downtime. I will take a look at it and if it seems to help then I can contribute to get help configuring it properly since I'm not that much of an expert

But just to be sure, you are confident the type of network I have can be handled by this? If so this piece of software is worth alot of money to us and will be rewarded accordingly.. I mean they sell machines that do this for like 3k. This is sort of ip-based traffic shaping right?

I'll post back after I upgrade to 2.0 snapshot

thank you for your reply so quickly

Sorry, my first post might have seemed out of context, I now read the entire thread, realized it spanned over a year and understood that you are pretty much done with this and it's included in pfsense2. however, pfsense2 is described as not recommended, I really REALLY want to try it but my 250 users might not like it if it fails, is it stable enough? or am i gonna have to go over there at 2 am next sunday because it crashes?

If you want to use it just for shaping and basic firewalling it should be safe to try.

Can you post your requirments so i can give you a suggestion on how-to?

matremblay

Like I said in my first post, it is a very simple network. I am not good with diagrams but I will try my best

Internet –-> Fiber-to-Ethernet Box ----> pfsense server --------> multiple unmanaged 10/100 switches -----> 250 end users
Point-to-point 10mbit/10mbit P4 computer some with gigabit uplinks wireless APs will most
Fixed Ip eth0 wan most of the network is wired likely be added next
to Telco eth1 lan (80%) for 10mbit, rest is 5e summer

About the server:

Right now it is doing everything

DHCP, DNS, NAT, Firewall, Traffic Shaper
Should these functions be divided in two computers to have the stable release sharing the internet, and another one shaping the traffic so that there is added redundancy or it is sufficient?

Server is 10.0.10.1 subnet is 10.0.10.xxx to 10.0.11.254

Objective is to offer fast reliable service for basic internet features for students : web, mail, IM, games, web phones/cams. and restrict p2p and other traffic that is clogging the network to a crawl

Recently the wiring was redone, so each floor (1 to 5) has a feeder coming from the first switch to its switch room, then two additionnal switches are connected to each other per floor.

I'm trying to include as much information but I think thats pretty much it

On a side note, the last pfsense I installed was from the "live cd" release. I noticed the 2.0 snapshots only say "alpha alpha". Is the install procedure still similar? Just to know what to expect.

Thank you in advance. Again if this is successful I'd be more than willing to pay you for your trouble and research if you supply me with a "custom" build and some support for setting it up (which is pretty much what you are doing now)

Thank you so much for everything so far!! I feel, and hope this might be the solution of many of my troubles of the past few months

Tomorrow morning I will go and install 2.0 over there

if you can post a few tips about the installation and configuration of the new features

i.e "limiter", and "http ack queue"

thanks ermal

matremblay

i installed 2.0 snapshot today, seems to be working well. However I would like help to configure the shaper and limiter for my needs if you dont mind

thanks in advance

Howdy,

It's been some time since I've played with pfsense, but right now I've got a hard drive with the "click of death" so I have to reinstall. For now, I'm trying 1.2.1-RC2, but since I'm now somewhere with a 30/5 and a 6.0/768 connection, I'd really like to try the new filter. I have not received any updates from Ermal regarding new builds for quite some time. Is there anything new forthcoming? Would a basic config from 1.2.1-RC2 work with the older snapshot?

Thanks

@sporkme
it is coming as i always said after 1.2.1 is released.

@matermblay
Run a traffic shaper wizard with pfSense for your needs that will take care of the prioritizing of ACK and protocols.
You may look at the rules generated to see if it actually what you expected.
For the limiter you need to decide if you want to divide equally the traffic to each user or youwant to assign more weight to http traffic and than less weight to other traffic.
Give me more details about what policy you need and i will recommend what changes you need to do to filter rules generated by the wizard to integrate the limiter in there.

As i said per protocol shaping/filtering is coming real soon but you can start with this one.

@ermal

thank you for your reply, I ran the shaping wizard but it stopped all traffic, then I saw another post that said it was looking at the "queue status" page that did this, so i will try running it again without looking at the queues monday, which wizard do you suggest i run based on my setup?

also in previous posts you told me i could increase http performance by making a http ack queue, could you teach me how please?

As for the limiter i tried setting the pipes but it did not do anything i must be doing it wrong. I would like to prioritize http but if it doesnt work i will split bandwidth to everyone equally.. something alongthe lines of 800kbitdownload/400kbit upload for all

thank you for your help

The ACK queue is created by the wizard and you can take a look at the rules generated the use that queue.
It will become clear when you see it configured.

For the limiter yes you created it but you have to apply it in the rules on the 'In/Out' section.
Depending on the needs.

matremblay

sorry i dont know if i am stupid or something but i really dont get the limiter. where is this in/out section?

I added the queues, checked the "enable" box, saved, and clicked apply settings
nothing, i can still download at 1000KB

In the rules! Firewall->Rules

Never got the PM about the traffic shaper to try out. ???

Thanks
