Hello i have encountering months now i problem with all my bittorrent
clients.
When iam downloading torrents with cleiant like Azureus, ABC etc after
10-15 minutes or so my connection is dropped/stops responding.

With p2p apps like emule/Limewire same thing doesn nto happen.

I cant explain it, can you?

I saw that MTU is Maximum Transfer Unit but still i dont know what its
about.
Can you please enlight me?
And also i looked at my web interface panel a http://10.0.0.138 to conf
MTU but didnt see an entry for that. From where ic an change this?!

Cable and dsl uses fixed numbers of MTUs?
The numbers are refering to bytes?

The MTU concept suprises me that it can vary because i thought that
every ip packet had a fixed size and it wasnt variable.

Why if it breaks it decreses perfomance?

And is there an option on XP that will allow me to change this MTU
value?

Set your MTU setting to 1430 or 1400 and see if that fixes the problem.

Hi.

Looks like bandwidth congestion, try using netlimiter to limit
bandwidth for each application accessing the net.

MTU is the size of the packet it can send before it has to break it into
many packets - if you set it for 1500 (cable modem) and you are using
DSL (1400) then it will have to break every packet into two parts to
send - which decreases your performance.

No, call your ISP.

Are you connected via a DSL or Cable Router NAT box or are you directly
connected to the Internet?

Cable uses a larger number because it mostly is faster and more like a
LAN than DSL.

DSL is mostly slower and more like ISDN (older method) and most times
ISP's run 1400 or 1430 for their size - I don't question it, just check
it and set it.

It's not broke, it's just not always detected and set to the Optimal
value - if you have a NAT box they often permit you to manually set the
MTU size - if you are using Windows XP connected directly to the
Internet, well you have a lot more problems than MTU size.

So, are you direct connect or do you have a router/NAT?

The maximum length of an IP packet depends on the link layer protocol,
and on the medium, and on any extensions supported end-to-end.
"IP" is a generalized protocol that in theory has quite large maximum
packets, but it is usually used over media such as twisted pair ethernet
that have much lower limits (for various reasons.)

Consumer broadband cable and DSL usually use MTU that are the same as
consumer ethernet, but the key to this puzzle is that there may be
additional protocol layers in use on the cable or DSL line that "use up"
some of the available bytes. DSL in particular often uses a format
known as PPPoE, which uses up 8 bytes per packet, leaving 1492 available.
Some DSL vendors use internal protocols that may use up a fair number
of other bytes.

One notable layer that uses roughly 150 bytes, is "IPSec", a
standardized protocol used to create Virtual Private Networks (VPNs).
Cable or DSL providers might have an IPSec layer active in order to
ensure the privacy of your communications -- but if they do then
the maximum packet size you might have left might go down to about 1340.
The end result is still 1500 bytes on the wire, but you only have
access to a portion of those with the rest going for overhead.

MTU is the maximum packet size an IP packet can have on a route; for
getting detailled information on this topic, you could read RFC 1191:

------------------------------ snip --------------------------------
When one IP host has a large amount of data to send to another host,
the data is transmitted as a series of IP datagrams. It is usually
preferable that these datagrams be of the largest size that does not
require fragmentation anywhere along the path from the source to the
destination. (For the case against fragmentation, see [5].) This
datagram size is referred to as the Path MTU (PMTU), and it is equal
to the minimum of the MTUs of each hop in the path.
------------------------------ snap --------------------------------

To configure maximum packages sizes being used by your device, have a
look into the documentation of this device.

Yours,
VB.

Sorry but I still dont understand how upload could help!
What i understanded so far is to set the MTU to 1430 or 1400 value
which is what iam trying at rhe moment to do through Tune-Up Utilities
app, since with xp i dont know from where i can change this value and
also routers web panl dont have an indication for that!

Thank you very much for the explanation of why an ip packet doesnt have
a fixed size but it varies cause of the layers encapsulate each part of
the information and the medium too.

you need to allow an amount of upload capacity to allow communication with
downloading sources or there will be a slowdown
As someone suggested, netlimiter could control that.

Well my setup is INTERNET >> ISP ADSL Modem/Router(1 device) >>
COMPUTER

Also in web panel i see no option to change MU so i change it through
an app called tun-up to 1430

Did i do well?

Archived from groups: comp.security.firewalls (More info?)

Still the problem persists although i have changed MTU to 1430.

Also what is bridged mode?

I cant afford now another router also

My router/modem is a SpeedTouch 530

ok.
When iam downloading torrents with client like Azureus, ABC etc. after
10-15 minutes or so my connection is dropped/stops responding.
Although some thing doesnt happen with eMule and Limewaire or kazaa
only with torrents.


I dont know why though. maybe its the mtu thats was set to 1500 and now
imatrying both 1400 and 1430 to see whats best.

Unfortunatelt my web panel doenst hae an option to set mtu of my
router.
So how would i know if its 1400 or 1430?

Although it might be the MTU i dont understand yet why it causes
problem.
Can you please explain to me in asimple detailed way?

Thanks in advance.

Ok, so don't adjust the MTU of your computer, you don't need to adjust
it. Only adjust the MTU setting of the NAT modem/router.

Just to make sure that I understand:

INTERNET >> ISP HARDWARE >> DSL ROUTER >> COMPUTER

If you are setup like above, you set the DSL ROUTER MTU, not the
computer MTU.

If you are setup like this (below):

INTERNET >> ISP DSL MODEM >> COMPUTER

Then you've got a lot of issues, the DSL MODEM should be in Bridge Mode,
then you install a DSL ROUTER (like in the top drawing), and you set the
MTU to 1430 for it.

Possibly, but, since I don't know the particular device your ISP is
providing, I can't say for sure.

Some DSL providers give their customers a fixed public IP, some only
give a NAT IP, but forward ALL ports through, others give NAT, but
forward nothing inbound.

If you can, ask your ISP to put the router in Bridge Mode and then get
yourself a Cable/DSL Router (like the BEFSR41) then you can change
settings at will.

Please describe the actual problem again - with as much detail as you
can.

> Also what is bridged mode?

Bridge mode set your route to provide a PUBLIC IP instead of a NAT
(private) IP, but it also means that you are fully exposed to the PUBLIC
and they can see your full computer - until you get some other form of
protection.

Have you considered the following:

Sorry for getting you off-track, MTU would impact most things, including
your other P2P apps.

I tried changing MTU to all those values. still the problem persists
but only with torrent cleiants.

Can i ty something else or we are sort of ideas?
