Some providers are throttling eMule traffic (decreasing the allowed bandwidth). They do this by detecting the eMule protocol and allowing a very limited amount of the total bandwidth to be used by eMule. Obfuscation makes it harder to identify the eMule protocol.

Some providers are throttling eMule traffic (decreasing the allowed bandwidth). They do this by detecting the eMule protocol and allowing a very limited amount of the total bandwidth to be used by eMule. The best reaction against this is to change ISP.
  
== Settings ==
+
* Before you are changing your ISP, please verify on the eMule under Options-> Security-> Protocol Obfuscation, that Enable Protocol Obfusaction is checked, otherwise you are unable to work with the Protocol Obfusaction on eMule.

However, by encrypting the eMule protocol, the provider cannot detect eMule easy and might allow more bandwidth to be used by encrypted traffic.
  
*Enable Protocol Obfuscation: Ask other clients to use obfuscated communications.
+
* Encryption (obfuscation) is only possible if both sides use encryption.
*Allow obfuscated connections only: If the other client doesn't understand obfuscation, any communication with it gets canceled. Use this setting only in extreme situations!
+
* It only protects (limited) against man-in-the-middle attacks.
*Disable support for obfuscated connections: The client behaves like it would be an older version which doesn't understand obfuscation.
+
* It does not increase your privacy since your data is still visible to other eMule clients that use the same encryption.
  
== Limitations ==

* Obfuscation only works if both sides of the transfer support it. If one side doesn't support it, the communication is done the "old" way, unless this is disabled (see ''Settings'' section).

* Obfuscation is not perfect, it is still possible to detect the eMule protocol.
+
* Obfuscation does not increase anonymity or hide which files are shared.
+
* If the provider doesn't try to detect the eMule protocol but rather blocks/limits every user which uses lots of bandwidth, obfuscation can't help at all.

== Earlier version ==
+
Neomule supported a different kind of obfuscation before official supported obfuscation. THis has become mostly obsolete since official emule supportes it.
