This means that you don’t get any benefit by starting multiple streams for downloading files as all datagrams (and thus TCP/IP connections) will use the same gateway.
How does your theory explain the fact I get 852 KB/s on the load balanced 543 KB/s DSL lines?
Oh, come on! I can’t believe no one uses proxy on Zeroshell! 🙄
It looks like there is no way to set up working QoS for VOIP phone, at least not using Linksys PAP2T adapter.
Correct me if I am wrong, but SIP travels over UDP ports specified per line, i.e. 5060 and 5061 in my case. I can QoS those.
But actual voice traffic travels over RTP protocol using port range specified per device, which would make it impossible to QoS that port range, as we don’t know which SIP port the RTP ports correspond to.
Basically with the way PAP2T handles VOIP, there is no way to direct one VOIP line’s traffic over one DSL connection, and other VOIP line’s to another.
Hoping I am making sense.
I have tried L7 sip pattern and it didn’t work for me..
Try by specifying ports.. Sip is UDP 5060
That works in a sense that port-based classification identifies VoIP traffic in statistics. Don’t know yet if it helps to improve voice quality though.
After looking at L7 manager, I have a question: are there actual protocol pattern definitions in Zeroshell? There seems to be only bunch of comments.
# SIP - Session Initiation Protocol - Internet telephony - RFC 3261, 3265, etc.
# Pattern attributes: good fast fast
# Protocol groups: voip ietf_proposed_standard

# Thanks to Ankit Desai for this pattern. Updated by tehseen sagar.
# SIP typically uses port 5060.
# This pattern is based on SIP request format as per RFC 3261. I'm not

# I have allowed version ranging from 0.x to 2.x.
#Request-Line = Method SP Request-URI SP SIP-Version CRLF
Not to hijack the thread, but once we are on QOS topic, is there any way to prioritize VPN traffic? I work from home using company laptop, which has Aventail VPN software installed. It uses a hard token for authentication. How can I set up a rule to prioritize its traffic 2nd to VoIP and give the rest lower priority?
Hoping someone can point me in the right direction about configuring QOS for the Linksys PAP2T adapter I am using.
I’ve added a VOIP class, classified it for SIP protocol, attached VOIP class to PPPOE interface and saved/activated everything. However there are no VOIP class packets in the Statistics window even as I am talking over the phone attached to the PAP2T.
My class definition is as follows:
1 * * MARK all opt — in * out * 0.0.0.0/0 -> 0.0.0.0/0 LAYER7 l7proto sip MARK set 0xd
PPPOE interface reads this status:
QoS Status:Enabled Max:5Mbit/s Guaranteed:5Mbit/s (Assigned:2%)
Tried to move VOIP class to ETH1 to which PPP is attached, to no avail.
What am I doing wrong?
