MikroTik

Does some P2P use http protocol? Is it covered by MT?

HTTP is a protocol that usually trasfers data over port 80. Other types of traffic can use port 80, also, and some P2P software can be set to use that port....

as far as I know Skype uses port 80

rastod - if you use mikrotik's P2P detection, it doesn't matter what port the software uses. RouterOS will filter it regardless of what port is set.

normis, have there been any changes in p2p detection since 2.8.27 ?

thnx!

not much that i know of.

I think he meant that some p2p can go over simple http protocol, not just over port 80, you can even use p2p through your http-proxy, would it be in this case recognized as p2p too?

As far as I know - yes, p2p blocking on MT works just fine for me

I can say the same, I still have a 2.8.23 and p2p filtering works fine for me.
Of course the client can change the port to 80 or another, but MK mangling is based on patterns and not just ports.

Hmm . . . not quite true. I reported several days ago that both Ares Lite and Regular versions 1.8.1 both get through MT when P2P set in drop mode.
I have MT 2.9rc7 running in bridge config with one firewall rule set for allp2p and action drop.

Waiting for an answer on this.

Thats right Ares and Kazza as i know can just jump the MT and they work fine, otherwise we have solved this problem by not stopping P2P but limiting overall bandwidth at 64/64 for all p2p and it works fine.

If Kazaa is unable to communicate on its standard ports, it will resort to using port 80. As of first version of Kazza Lite, this has been the case. There is no stopping it, you can only try to throttle it. which can also ne to the detriment of legitimate http users.

dont understand what you say. if you can mangle the kazaa traffic (recognise it) then dropping or limit it is the same work.

can you explain it better ?

> we have solved this problem by not stopping P2P but limiting overall bandwidth at 64/64 for all p2p and it works fine.

yes, I'd be interested in explaining this more. Did you try the newest Aries? Does your post mean that if you drop p2p totally, it still works unlimited but when you limit p2p to 64kbit, it is being catched and throttled down ?

thnx.

well pls can u post th ecoding for limiting the p2p softwares to 64k/64k
cause i am having this problem. also does each costumers has this limit or all of them combined toghetehr will have this limit.
thanks a lot for u guys
