In 1.2.3 there is a limit that you are hitting.
This has been upped quite a lot in 2.0

you can use layer7 for this.
Just create a regex for facebook and map it to the queue pipe you want.
The only problem is you cannot filter on https and that's most of their traffic now days.

How to set the limited bandwidth for client ?
http://forum.pfsense.org/index.php/topic,33160.msg172696.html#msg172696

In firewall/traffic shaper /limiter section in ur web-guy create 2 pipe with the speed u need to limit. in mask field use "destination" for both pipe.

now in firewall/rules/lan section create a rule with following

action–------pass
interface ------lan
protocol-------any(to shape all kinds of traffic)
source-------------(single host or alias)  ip address u want to shape
destination----------any

now in advance features ------in/out tab click on "advance" & select 1 pipe for in field & other for out. dont use same pipe for both.

now save & apply change.

now in firewall/rules page put this rule to above the default rule. done for 1 ip.

you may confused about the mask of pipes as they are both destination. dont worry they will work.

@jimp:

Use the single WAN multi LAN wizard, and enter 1 for the number of LANs. That works.

Thanks for the advise, just tried and still no luck.

"You do not have 1 of local interfaces!"

The point of QoS is NOT to have the queues build up, not use all the bandwidth, so if you keep accepting packet at the maximum rate (and thus increasing latency for incoming packets), it's already to late to do shaping, the packets already arrive with a delay.

You can't control what packets are sent to you directly.

You can manage and control bandwidth through conference manager application. This will allow the minimum bandwidth required for video conferencing and will not make the whole system busy

So it reaches 100% CPU?  ???

If so, polling might help:

Thank you!  That makes complete sense to me now.

Maybe you want to change to PRIQ and put your game (and VoIP maybe?) in highest priority together with the ACKs?

Sorry to dig up an old thread…
In my case where I am running 1.2.3 and experiencing the same problem, I can get the up packets to go into the qvoipup if I remove the tos_audio=ef line in asterisk.  But I'm wondering if this is the proper way to resolve this particular qos issue?  Or are there any other suggestions short of going back to 1.2.2?

Thanks in advance

You might want to read the pfSense book then.  The traffic shaper works fine in 1.2.3 but you have to configure it correctly.

hi, again…
i just cant get this thing to work...
have managed WAN, LAN, WIFI (third NIC + wifi router)
works all great..
but i want to manage bandwith for WiFi and all i get are errors...
Is the error on my side ? doing someting wrong? or are there some bugs?
Sorry...im not an expert..but really love this PF Sense :P
Any help?

All the created rules are settled at "floating" rules.
What i did (maybe silly), was creating aliases for the specific ports and reduce the amount of rules here. Looks better and is easily to maintain.
