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 which is a file which's contents 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 (eMule's PeerGuardian format, which is the most popular. The antip2p.txt format isn't yet supported).

Hard coded IP filter in aMule

aMule has a range of IPs which it filters by default following the RFC 3330 document. This 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 this range 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").
