Not Ubuntu but NetworkManager in general. As said on the wiki page, one
needs to nail down the MAC address for NM to dish out the same IP.

I use the following on many boxes, so the version numbers can be off a


create /usr/local/sbin/
create /etc/udev/rules.d/80-freerunner.rules
cd /etc/udev/rules.d/
chcon --reference=40-multipath.rules 80-freerunner.rules
chmod 744
udevcontrol --reload_rules

Depending on how your firewall is set up, you may or may not have to
issue the following

iptables -A POSTROUTING -t nat -j MASQUERADE -s
iptables -I FORWARD 1 -s -j ACCEPT
iptables -I INPUT 1 -s -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
