When eMule is running it reports malicious traffic from my machine in it's IDS nearly all the time. This is no real problem, since I have unchecked the "enable auto-blocking" option, but it is REALLY annoying. One can get rid of it by adding the IP to the "trusted adresses" entry, but with a dial-up connection (as in my case) this helps only until next re-dial...
Hi,
On ISS BlackIce exists an option that accept all the connection by a rules. So, you must go to the Tools menu, Advanced Firewall Settings and on the opened new window, add two rules. One is for the TCP port ( 4662 ) and another for the UDP Port (whatever) adding both with the options: accept forever, mode accepted, and all IP adresses activated.
Also you must check Nervous Mode or less on Blackice setting because paranoid mode stop all the traffic (also p2p). You can then activate autoblocking, internet file sharing and netBios (if you need it for a lan) options.
Also in my case, I detected some problems with P4 HyperTreading CPU, if I select the option to "force" emule.exe to work on one of the two CPU it crashes everytime. There is only one CPU in my PC but P4 HT tech. emulate two CPUs, so I can select for exemple CPU0 for Windows programs (except svchost) and CPU1 for others programs as emule, kazaa or openoffice, etc.
There is a firewall freeware program called NetPeeker that can run fine with emule but, if I activate the option to balance my conection (or limit the speed of a program as emule) both of them crash.
Regards

It is worse When I use it for a LONG time, say emule is running 2-3 days in a row. But the situation starts getting bad after a couple hours of use.
This is waht happens : Imapp.exe (part of the norton firewall, that tracks connections starts using more and more CPCu cycles as it tries to monitor all incoming outgoing traffic. Net result : it ends up using 70-90 % of CPU making all other programs sluggish.
If I stop Emule it reverts to normal.. if I restart it it starts misbehaving again. Bleech.

I seen there is plenty of problems with firewalls and antivirus software.
Let me bring you my nearly 4 years use of p2p appz.
First of all : you need a machine wich can cope with what you ask it to do.
I mean running Emule on an old machine will not work, especially if you run FW and AV soft on side of it.
I split the explanation in two parts : connection and CPU wise.
Connection wise :
Looking back to history, most of OS'es/network softwares for the desktop users have been build to cope with about 10 concurent connections, wich was far enough for dial-up modems. (keep it in mind for later)
When Emule connects, it makes MAX CONNECTIONS at the same time. It consumes a lot of upload. Your upload becomes saturated as soon as you connect to a server. It's why you have slow connection then. You can't ask the website for all the content on the webpage. So you have a blank page for seconds.
The most important thing to know about ADSL technology is that download is reduced by 50-75% when upload is saturated. So reduce your MAX CONNECTIONS and reduce your UPLOAD LIMIT when you connect will helps.
Of course when you will have most of your sources you will be able to increase back the UPLOAD LIMIT to 80% of your theorical ASDL hardware limit.
Also the management of connections within Windows 9x/ME is very bad, so do not expect to have a nice network behaviour with these OS'es. A turnaround can be to tweak their registry to improve their capabilities a bit . Check http://www.speedguid...t/downloads.php for different patches but do not expect miracles.
On the side of this problem inherent to ADSL technology, there is the firewall management of these connections. Most of them can't handle 100+ concurent connections. Only a few can manage 600+. Also, Emule use dynamic ports, wich confuse most of them. I tried ALL of them, analysing for hours their behaviour(logs parsing, packet sniffing, cpu and RAM allocation measures). The conclusion is that only Sysgate Firewall works perfectly with Emule. Even the latest version of ZA or NortonPF drops packets or becomes instable after a while. I do not explain it further 'cause i don't want to make a 10 pages post, but I can discuss it more deeper. I want to precise I'm not involved in any way with Sygate company.
There is a free version of it on www.sygate.com, and the professional version works PERFECTLY with Windows ICS, wich means you can have a safe network, easy to use, and most of it Sygate do not consumes a lot of CPU. But I prefer to use a hardware firewall, it's far more safe but a lot more complicated to setup.
CPU side of the problem.
The CPU is not too much important on Emule on a powerfull system. But on low specs systems it can become problematic, especially with AV softwares and large files. NortonAV works very well with emule, with Windows W2k/XP indeed, and it might be the same with the others. If any AV is a problem on your system, remove the autoscan feature. It should save you a large amount of CPU.
Erf I'm tired I will continue this post later if you need more info or precisions.
Good luck.

At first I had some minor firewall problems, and I installed it to try to fix these.
But in the end, the firewall worked fine, but some component of ultrasniffer
(Called netpryer.sys) somehow made emule crash, even if I was not running ultrasniffer
I uninstalled it, and everything was fine

You should disable real-time scan of eMule temporary folder.

Yeah... right...
All my WIN98SE computers (have 4 of them) have worked with no problems for years, through many reformats. My WINME computer has too.

hello MichelSup
have you tried using emule with the outpost firewall pro 2.0? i just installed sygate personal firewall pro 5.5 and it works great, but i miss the flash/ad/popup blocker from norton internet security, and outpost has that feature.

eMule creates a lot of connections, this puts a heavy load on the networking subsystems and brings to light any problems/flaws that are inherent in the system. As a result a poorly made firewall/network stack will have any problems highlighted that may not show during ‘normal’ operation.
If your computer freezes and becomes unresponsive while running eMule it’s probably your firewall. This comes from a firewall that does not flush its connection table properly/at all, since most modern firewalls operate at a low level they will cause the operating system to halt while they inspect incoming packets and pass them on if they are ok. Normally this would happen very quickly and everything would be fine. But if the connection table becomes very large (like when eMule has been running for a while) and does not get flushed each packet that is inspected causes a pause on the system as the lookup time gets larger and larger.
A good firewall will flush TCP connections that have been closed and time out UTP 'connections'. This should result in a table that consists of only active connections. As a backup there should be a cleaner thread that goes through periodically invalidating and clearing entries that have not closed/timed out properly.
But alas, not all firewalls are created equal and as such most have problems dealing with eMule. Before you people who have ZA working fine harp up, be aware that the more connection that been created directly influences this behavior. So eMule may run fine if you have 2000 sources but may cause problems when you have 20,000, also factors such as max connections and connections per 5s can influence how many a created over a set period of time which determines the size of the connection table.
Also on another note, please be aware that some firewalls operate by use of virtual device driver, this results in the firewall client program to show no CPU usage, other like Norton have the main process doing the work and will show CPU usage.
PS: I’m a CompSci Major with a specialization in security so I sorta know what I’m talking about, but comments/criticism is most welcome.
