USB networking with Ubuntu 9.04

[Sander van Grieken]

Why use a script that you need to run manually each time?

It can be done automatically just by putting the right stuff in /etc/network/interfaces:

auto eth2
iface eth2 inet static
  address 192.168.0.200
  netmask 255.255.255.0
  post-up iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE
  post-up echo 1 > /proc/sys/net/ipv4/ip_forward
  post-up route add -host 192.168.0.202 dev eth2
  post-up dnsmasq
  pre-down echo 0 > /proc/sys/net/ipv4/ip_forward
  pre-down iptables -t nat -D POSTROUTING -s 192.168.0.0/24 -j MASQUERADE
  pre-down killall dnsmasq


when you plug in the FR, eth2 will activate automatically..
