#1 Phase 3: WLAN Routing Support

[Mark Wallis (aka serialmonkey)]

Phase 2 of the project will be focused on incorporating routing
functionality into the device. This will allow the WLAN interface to be
setup as a WAN connection with appropriate NAT and firewall
configuration available.

Phase 2 will incorporate all features from Phase 1 plus the following
* Routing mode with WLAN interface as WAN connection
* Firewall and NAT configuration
* DHCP Client and PPTP Client for WAN connection

This feature request will be expanded out into multiple task-specific
RFE's once this feature is fully scoped using community input.

Dynamic routing protocols such as OSPF, RIP, etc will also be
investigated as part of this phase.

This would be good for people that have a WISP type of
Internet connection, the same configuration would also allow
setting up the opposite, vis: Wired connection to internet
with wireless only clients, kind of like a Internet router
with zero wired ports.

Routing: appropriate Kernel configuration
Firewall & NAT: iptables rules to set up WAN & LAN using
environemnt variables for the interfaces, would allow either
configuration ( wireless WAN & Wired LAN or Wired WAN &
wireless LAN ) by flipping two variables.
DHCP client: can be built as part of busybox now.

May also want to use DNSMASQ to do the DHCP Server and DNS
proxy in one hit.

We will look at this after the OpenWRT migration.
