How to share network connection from eth0 to wlan0 in AP mode?

[k3ll]

Hi,

I have some issues trying to configure my BBB as fully functional AP.

The BBB is connected on eth0 to my home router. eth0 is a DHCP client for my home LAN.

home router [DCHP server] --- ETH0 [DHCP client] --- BBB --- Wlan0 [AP & DHCP sever] --- My laptop [DHCP client]

I managed to enable AP mode on a wifi USB dongle.

From the BBB i can ping google.com.

I can successfully connect to the BBB from my laptop acting as a WiFi client.

I am not able to surf the web from my laptop.

some conf files:

cat /etc/network/interfaces

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet dhcp

# WiFi

auto wlan0

iface wlan0 inet static

address 192.168.10.1

network 192.168.10.0

netmask 255.255.255.0

broadcast 192.168.10.255

hostapd /etc/hostapd/hostapd.conf

_________

 cat /etc/hostapd/hostapd.conf

interface=wlan0

### Set your bridge name ###

#bridge=br0

#driver

#driver=8192cu

country_code=IT

ssid=bblack_iot

channel=7

hw_mode=g

# # Static WPA2 key configuration

# #1=wpa1, 2=wpa2, 3=both

wpa=2

wpa_passphrase=*********

## Key management algorithms ##

wpa_key_mgmt=WPA-PSK

#

## Set cipher suites (encryption algorithms) ##

## TKIP = Temporal Key Integrity Protocol

## CCMP = AES in Counter mode with CBC-MAC

wpa_pairwise=TKIP

#rsn_pairwise=CCMP

#

## Shared Key Authentication ##

auth_algs=1

## Accept all MAC address ###

macaddr_acl=0

#enables/disables broadcasting the ssid

ignore_broadcast_ssid=0

# Needed for Windows clients

eapol_key_index_workaround=0

I tried bridging wlan0 and eth0 but in that case I should assign static IP to br0, and I can't, I need the network interface connected to my home router to have a dynamic IP address..

Any idea on a possible configuration?

Thanks!

So, we actually have this setup in the default image's..

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Image_Testing_Snapshots

As long as eth0 is present, wlan0 get's setup as wifi ap, routing all
trafic upstream eth0..

Behind the scene's it's actually connman doing the work, remove wlan0
from your /etc/network/interfaces

and just run:

sudo connmanctl enable wifi
sudo connmanctl tether wifi on bblack_iot ${wifi_password}

Or just grab the IOT image on a 2nd microSD card:

bone-debian-*.img.xz

you can also manually edit

/var/lib/connman/settings

here's our defualt:

**************
[WiFi]
Enable=true
Tethering=true
Tethering.Identifier=BeagleBone
Tethering.Passphrase=BeagleBone
**************

and just:

sudo /etc/init.d/connman restart
