Igmpproxy настройка на шлюзе Linux Debian

• Установка на системе Debian 10 и настройка igmpproxy поэтапно:

• Скачиваем igmpproxy:

wget -c https://github.com/pali/igmpproxy/archive/refs/heads/master.zip

или

git clone https://github.com/pali/igmpproxy.git

• Сборка пакета:

cd igmpproxy
./autogen.sh
./configure --prefix=/ --sbindir=/usr/sbin/ --sysconfdir=/etc/
make -j2
sudo checkinstall -D -y --pkgname=igmpproxy --pkgversion=0.3 --install=no

• Установка:

sudo dpkg -i igmpproxy_0.3-1_amd64.deb

• Настройка:

Так как к сожалению нет в исходниках готовой поддержки deb, скрипт запуска делаем сами:

touch /etc/init.d/igmpproxy
mcedit /etc/init.d/igmpproxy

Вставляем:

# Short-Description: IGMP multicast routing daemon
# Description:       IGMPproxy is a simple dynamic Multicast Routing Daemon
#                    using only IGMP signalling. It's intended for simple
#                    forwarding of Multicast traffic between networks.

:

и сохраняем.

присваиваем права на запуск:

chmod 0755 /etc/init.d/igmpproxy
chown root:root /etc/init.d/igmpproxy

устанавливаем автозапуск:

update-rc.d igmpproxy defaults

• Пояснение: эти настройки для init.d для systemd требуется иное.

теперь пример конфига:

#
#   Example configuration file for the IgmpProxy
#   --------------------------------------------
#
#   The configuration file must define one upstream
#   interface, and one or more downstream interfaces.
#
#   If multicast traffic originates outside the
#   upstream subnet, the "altnet" option can be
#   used in order to define legal multicast sources.
#   (Se example...)
#
#   The "quickleave" should be used to avoid saturation
#   of the upstream link. The option should only
#   be used if it's absolutely nessecary to
#   accurately imitate just one Client.
#

для того, чтобы понять какой порт у вас работает используйте nmap, пример:

nmap -sU 192.168.0.1 -p U:100-1000

Должен показать порт UDP:

..
123 UDP

• На IPTv плеера укажите ваш UDPROXY: 192.168.0.1:123
