Revision as of 20:39, 6 July 2013

I believe the topic of Internet connection sharing from a Windows/Linux/Mac host to BeagleBone's USB virtual network connection could be elevated to its own page as I believe this is a common use-case. In the case of Mac, I've found http://apple.stackexchange.com/questions/73485/internet-sharing-from-wifi-to-ethernet-doesnt-work-in-mountain-lion, but haven't had time to try it.

This worked for me: https://discussions.apple.com/thread/5152615

Here's my whole script:

#!/bin/sh
BEAGLE_ADDR=192.168.7.2
HOST_ADDR=192.168.7.1

sudo sh -c <<SCRIPT
gwdev=en0
targetdev=en1
/sbin/ifconfig $targetdev down
/sbin/ifconfig bridge0 create
/sbin/ifconfig bridge0 up
/sbin/ifconfig bridge0 addm $gwdev
/sbin/ifconfig bridge0 $HOST_ADDR
/sbin/route add default -interface bridge0 -ifscope bridge0 -cloning
/usr/sbin/sysctl -w net.inet.ip.forwarding=1
/sbin/ipfw add 100 divert natd ip from any to any via $gwdev
/usr/sbin/natd -interface $gwdev -use_sockets -same_ports -unregistered_only -dynamic -clamp_mss -enable_natportmap -natportmap_interface $targetdev
SCRIPT

ssh-copy-id $BEAGLE_ADDR
scp /etc/resolv.conf root@$BEAGLE_ADDR:/tmp
ssh root@$BEAGLE_ADDR "cat /etc/resolv.conf >> /tmp/resolv.conf.orig"
ssh root@$BEAGLE_ADDR "cp /tmp/resolv.conf /etc/resolv.conf"
ssh root@$BEAGLE_ADDR "/sbin/route add default gw $HOST_ADDR"
