1) Flash the NetGear device with the appropriate image:

  openwrt-ar71xx-wndr3700v2-jffs2-factory.img -> WNDR3700v2
  openwrt-ar71xx-wndr3800-jffs2-factory.img   -> WNDR3800

Configure a computer's ethernet port to: 192.168.1.2/24 (.1 is used by
the router) and execute the following procedure:

  http://wiki.openwrt.org/toh/netgear/wndr3800#recovery.flash.in.failsafe.mode

2) Execute the "First Login" procedure described in:

  http://wiki.openwrt.org/doc/howto/firstlogin

This will enable SSH for subsequent logins.

3) Login via SSH and perform the following procedure:

# From the OpenWRT repo:

# Note: some of the packages might already be installed

opkg update
opkg install bash
opkg install dnsmasq
opkg install firewall
opkg install ip
opkg install iptables
opkg install iptables-mod-conntrack
opkg install iptables-mod-nat
opkg install kmod-ip6-tunnel
opkg install kmod-ipt-conntrack
opkg install kmod-ipt-core
opkg install kmod-ipt-nat
opkg install kmod-ipt-nathelper
opkg install kmod-iptunnel6
opkg install kmod-ipv6
opkg install libpcap

# From the ISC repo: (note the 4 is the version of the distrib)

# dhcp4-client

opkg install http://bikeshed.isc.org/~fobispo/sdcpe/packages/ar71xx/packages/dhcp4-client_4.2.3-P2-sdcpe-2-1_ar71xx.ipk

# dhcp4-dhccra

opkg install http://bikeshed.isc.org/~fobispo/sdcpe/packages/ar71xx/packages/dhcp4-dhccra_4.2.3-P2-sdcpe-2-1_ar71xx.ipk

# dhcp4-server

opkg install http://bikeshed.isc.org/~fobispo/sdcpe/packages/ar71xx/packages/dhcp4-server_4.2.3-P2-sdcpe-2-1_ar71xx.ipk

# sdctld

opkg install http://bikeshed.isc.org/~fobispo/sdcpe/packages/ar71xx/packages/sdctld_rt28354-1_ar71xx.ipk

4) Config and scripts

Apply the step explained in README

5) Remove udhcpc (legacy DHCPv4 client) and dnsmasq DHCP support

rm /sbin/udhcpc
mv /usr/sbin/dnsmasq /usr/sbin/dnsmasq-
opkg remove dnsmasq
mv /usr/sbin/dnsmasq- /usr/sbin/dnsmasq

6) Enable the SDB4 bundle by editing: /etc/rc.local and adding:

  /etc/sdb4/rc start

before the "exit 0" command (cf sdb4/rc.local)

7) That's all... now look for the requests on the DHCP servers
   (DHCPv6, TSV) and add the appropriate DUIDs and MAC addresses so
   that the CPE can obtain addresses.
