What are the steps to be taken to have Skype prioritized with the new ROSv3.0 running in my network?

I should use that new Layer7 Protocols option?

What is the "Regexp" string for Skype and do I need to have more settings set in the firewall?

I have now basically all P2P traffic blocked (standard Firewall filter rules) and have natting with masq on all client units.
AP-routers have all kind of filtering with Qos for normal VOIP traffic.

Who can give a nice setup that would then also qualify for the Wiki? (And you can have all the credits! )

Kijomabb,

As you could have read in my initial question that's not the manner I'm looking for. I will have loads of Skype users in my network and I'm not planning to explain them all how to set a port in the software.

Also, don't bother about the file P2P capabilities of the Skype network, speeds are kept very low by Skype itself It won't hurt a network with a bit of capacity and the file transfers are not in P2P modus.

We need to mark Skype traffic with the layer7 protocol and then use that marker to identify the traffic streams whereafter we can prioritise that traffic in
mangle or something like that.

Skype doesn't care about ports, it uses whatever ports it needs, and in some cases even pretends to be HTTPS traffic, so marking skype (for blocking or prioritising, doesn't matter) is extremely difficult. you can mark some of it with L7:

you can then make queues for skype and non-skype traffic and give them priorities

Skype doesn't care about ports, it uses whatever ports it needs, ...........

Normis; to be compleet, Skype client software does have the option to set a certain port. But that option is disabed per default. And if it is enabled and a port has been assigned while that port then is blocked somewhere else Skype will still use any other port.

But, in theory you CAN prioritise Skype by picking a certain port. (For each client another one to avoid problems in silmultanous use by clients) and then set the client to use that port. Actually you just help any traffic that uses that port.

In real life this would be too complicated and a waste on ports (how many do we need?)
In limited controlled networks this could be a way of doing it though...

Layer7 Protocol
name: SkypetoSkype
String: ^..\x02.............

Mangle
Layer7 Protocol: SkypetoSkype

I want to ask that if i can to make perioritize for sky & other live IM ???

How do you get the microphone to work on my bluetooth headset for Skype? I have a BlueAnt bluetooth wireless headset. I can get the earphones to work with Skype but not the microphone. I select the microphone for the headset in Skype but that doesn't work, so I have to use the micropone on my computer.

Sorry about that. But this forum is for MikroTik RouterOS and network related discussion.


Anyone succeeded in prioritizing Skype to Skype Voice UDP traffic ?

Anyone succeeded in prioritizing Skype to Skype Voice UDP traffic ?

I use L7 identifier and leave the protocol argument behind. Skype can use whatever it thinks it need so if you want to catch Skype you either need to make a L7 rule for tcp and udp or just one rule (lesser = better) for both.

I tested it and as far as I can see the Skype traffic is mangled sufficiently.

WirelessRudy, can you please share with us your L7 pattern for Skype-to-Skype traffic? it sounds crazy that it works =)

http://protocolinfo.org/wiki/Skype

Check these links out for Skype.
I have no proof it works 100% but without using these my Skype quality is poor. When L7 in use the quality is much better and much less connection cuts.
Skype to Skype works better though then Phone to Skype or Skype to phone.

I tested with client that was downloading, at the same time remote desktop and the communication between us was done with SkypeToSkype. Clear lines and sometimes connections for more then 20mins while network was busy too...

It is still happening at times that some connections in general (over all my users) are dropped but that is more because my network has only 2.2Mb upload capacity and with 100+ Skype clients, several P2P users and some remote desktop and VOIP users at times the ceiling is hit and some connections suffer.
After all, Skype and VOIP and Remote Desktop (SSL) traffic all get the same high priority which at times does not have enough capacity.
And sometimes when I have a Skype conversation with family in absolute slack time on my network connections still drop. This must be Skype or general internet performance related...

But using L7 improved things for me....

P.S.
Not to forget; have, and your users too, the latest version of Skype installed. It makes a difference! (Special against versions older then 6 months.)

I can never trust a Layer7 pattern. It will catch packets that do not belong to Skype. Doesn't skype have small size UDP packets? Can't we just prioritize them? Or lets say we use the L7 pattern. How can we make a very clever mangle setup that jumps around the second a packet is detected to be Skype to Skype, and matches the small UDP pattern, is jumped out of reach of the L7 rule, to save CPU, and the connection itself is already marked as priority.. I have done similar things... with mangle action jump....

Here are the best configurations. https://www.mansooryousaf.com/blogs/mik ... igurations
