UDPXY (RPi) WITH 2 NETWORK INTERFACES

Udpxy is UDP-to-HTTP translator for IGMP streams.
Forked from agrrh/docker-udpxy

In this version, i will guide you how to config UDPXY to proxy multicast stream into HTTP, using Raspberry Pi with 2 network interfaces, one for getting multicast stream from IPTV Provider (ISP), and other is for internet connection/your LAN network.

This has been tested to work perfectly with ARM, ARM64, x86-64, Raspberry Pi 4 (2GB).

Config

• First, we need to make sure that our 2 network interfaces are all up and running normally. To do that, we type this command in terminal. If not, you will have to check it by yourself :-)

pi@raspberrypi:~ $ ifconfig
...

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.0.155  netmask 255.255.255.0  broadcast 172.16.0.255
        inet6 fe80::107d:9fde:4188:c9db  prefixlen 64  scopeid 0x20<link>

        inet 10.11.xx.xx  netmask 255.255.254.0  broadcast 10.11.xx.xx
        inet6 fe80::d195:ae9c:edc6:3906  prefixlen 64  scopeid 0x20<link>

...

• As we can see here in my case, eth0 is the interface that will connect to the internet, as well as my local LAN network. And eth1 is the interface that connect directly to the IPTV Provider.

• Our mission here is to proxy multicast stream from eth1 to eth0. Let's begin!

Dockerfile Config

FROM buildpack-deps as builder

ARG UDPXY_SRC_URL
ENV UDPXY_SRC_URL=${UDPXY_SRC_URL:-"http://www.udpxy.com/download/udpxy/udpxy-src.tar.gz"}

WORKDIR /tmp
RUN wget -O udpxy-src.tar.gz ${UDPXY_SRC_URL}
RUN tar -xzvf udpxy-src.tar.gz
RUN cd udpxy-* && make && make install

FROM debian:stable

COPY --from=builder /usr/local/bin/udpxy /usr/local/bin/udpxy
COPY --from=builder /usr/local/bin/udpxrec /usr/local/bin/udpxrec

# service will run at port 4022
# receive multicast stream through eth1 interface
# serve max 50 CCU
# Renew subscription each 180 secs (i.e. 3 mins)
ENTRYPOINT ["/usr/local/bin/udpxy"]
CMD ["-m", "eth1", "-v", "-T", "-p", "4022", "-S", "-M", "180", "-c", "50"]

• In the Dockerfile, replace eth1 with your current multicast-enabled interface in config step.
• You can also change the service port 4022 with your desire port.

Build docker

• After each time you change the Dockerfile, you have to build/re-build the docker image in order to apply those new changes.
• To build docker image, simply just run:

docker build . \
  --build-arg UDPXY_SRC_URL=http://www.udpxy.com/download/udpxy/udpxy-src.tar.gz \
  -t khaidq/udpxy

Usage

• Hit this command into your terminal

# Run container as daemon

docker run -d --name udpxy \
  --network host \
  --restart unless-stopped \
  khaidq/udpxy \

• Example of opening a multicast link in VLC:
