IPFilter

English | Deutsch

Description

The IP Filter blocks traffic from/to IPs and ranges of IPs with our client. This means that those IPs which get blocked will not be able neither to upload to us nor to download from us.

This filter is read from ~/.aMule/ipfilter.dat and ~/.aMule/ipfilter_static.dat. The content of these files describes the valid and blocked IP ranges.

ipfilter.dat file

The information and details about the ipfilter.dat file can be found here.

Using the IP Filter in aMule

The Access level of the IP filter is selected in aMule through "Preferences" -> "Security" -> "IP Filtering" -> "Filtering level" (in aMule versions up to 2.0.0-rc8 it is under "Server", instead of "Security").

NOTE: aMule's ipfilter.dat file is 100% compatible with eMule's.

Using an external ipfilter.dat file

aMule by default uses ~/.aMule/ipfilter.dat for IP filtering. If you enable 'Use system-wide ipfilter.dat if available', it will look for a /usr/share/amule/ipfilter.dat file if loading the local ipfilter.dat fails.

The above paths assume a linux-like system.

This option is located through "Preferences" -> "Security" and is disabled by default in the latest stable 2.2.2 build.

IP Filter sources

IP Filter - URLs for Auto-update at startup

Insert the URL under "Preferences" -> "Security" -> "IP filtering" -> "URL:"

http://emulepawcio.sourceforge.net/ipfilter.dat (updated monthly) Unfortunately the header lines of this .dat file confuse aMule 2.2.3 (the newest aMule as I write this) so the header lines (starting with #) need to be removed before aMule will successfully load this file. To accomplish this let aMule download the file as normal, check the aMule log to see where aMule stored the file (it seems to stored it in ~/Library/Application Support/aMule/ipfilter.dat on a Mac), then open this file with a text editor and remove all the header lines starting with #'s, then press the 'Reload List' button in the aMule Security Preferences to get aMule to reload the file.

IP Filter sites

You can insert the lists from these sites either manually or with a script. Or you can use seperate IP-blocking software like Protowall from Bluetack, PeerGuardian from Phoenixlabs or moblock.

The lists from Phoenixlabs (formerly known as Methlabs) are still under development. They use the lists from Bluetack instead.

Hard coded IP filter in aMule

aMule has some ranges of IPs which it filters by default following the RFC 3330 document. These ranges are:

        Address Block             Present Use                       Reference
        ----------------------------------------------------------------------
        "0.0.0.0/8",       // "This" Network                 [RFC1700, page 4]
        "10.0.0.0/8",      // Private-Use Networks                   [RFC1918]
        "14.0.0.0/8",      // Public-Data Networks         [RFC1700, page 181]
        "24.0.0.0/8",      // Cable Television Networks                    --
        "39.0.0.0/8",      // Reserved but subject
                           //    to allocation                       [RFC1797]
        "127.0.0.0/8",     // Loopback                       [RFC1700, page 5]
        "128.0.0.0/16",    // Reserved but subject
                           //    to allocation                             --
        "169.254.0.0/16",  // Link Local                                   --
        "172.16.0.0/12",   // Private-Use Networks                   [RFC1918]
        "191.255.0.0/16",  // Reserved but subject
                           //    to allocation                             --
        "192.0.0.0/24",    // Reserved but subject
                           //    to allocation                             --
        "192.0.2.0/24",    // Test-Net
        "192.88.99.0/24",  // 6to4 Relay Anycast                     [RFC3068]
        "192.168.0.0/16",  // Private-Use Networks                   [RFC1918]
        "198.18.0.0/15",   // Network Interconnect
                           //    Device Benchmark Testing            [RFC2544]
        "223.255.255.0/24",// Reserved but subject
                           //    to allocation                             --
        "224.0.0.0/4",     // Multicast                              [RFC3171]
        "240.0.0.0/4"      // Reserved for Future Use        [RFC1700, page 4]

However, you can un-filter these ranges of IPs by unchecking "Preferences"->"Security"->"IP-filtering"->"Always filter bad IPs" (on aMule versions up to 2.0.0-rc8, this option can be found in "Preferences"->"Server"->"Always filter bad IPs").
