Setting up internet access on Raspberrypi4 #15

Open maryum375 opened 4 years ago

maryum375 commented 4 years ago

Hi, I encountered this project looking for a way to setup my raspberrypi 4 as a wireless router for my iot devices. I pulled and started the container using: $ sudo docker run -d -t -e INTERFACE=wlan0 -e CHANNEL=6 -e SSID=RanIOT1 -e AP_ADDR=192.168.4.1 -e SUBNET=192.168.4.0 -e WPA_PASSPHRASE=passw0rd --privileged --net host sdelrio/rpi-hostap:latest

And it seems to open the wireless hotspot. The thing is that this hotspot is not connected to the internet. what did I do wrong? This is the log of the container:

Thanks a lot for your help!

Doesn't seem you set OUTGOINGS env variables, look at README.md example and set up that. By thefault this set is disabled if you don't set

OUTGOINGS | false | Interfaces to external traffic

I run as readme file says but I'm haven't internet connection too sudo docker run -d -t -e INTERFACE=wlan0 -e CHANNEL=6 -e SSID=runssid -e AP_ADDR=192.168.254.1 -e SUBNET=192.168.254.0 -e WPA_PASSPHRASE=passw0rd -e OUTGOINGS=eth0 --privileged --net host sdelrio/rpi-hostap:latest also when I run it I get on my raspberry pi 4:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

sdelrio commented 1 year ago

The image is from +5 years ago, and docker probably added some extra check for the image which was not set before and was using amd64 by default even if it was arm image. Added build-multiarch: in the Makefile buildx for multiarch image and pushed a new tag 0.31 to the dockerhub. Now the image should be valid for:

linux/amd64 linux/arm/v7 linux/arm64

same, no internet connection

I had the same problem on a Pi4 with Raspian 6.1.0-rpi8-rpi-v8 and was able to fix it by enabling the flags net.ipv4.ip_forward=1 and net.ipv6.conf.all.forwarding=1 on the host /etc/sysctl.conf to allow forwarding.

sudo nano /etc/sysctl.conf #net.ipv4.ip_forward=1 -> net.ipv4.ip_forward=1 #net.ipv6.conf.all.forwarding=1 -> net.ipv6.conf.all.forwarding=1
