----------------------------------------------------

Managed Internet Gatewaying:
In this mode there are two different types of nodes, Gateway Nodes and Client
Nodes. A Gateway node requires two interfaces, one which hooked up to the normal
network and another which will connect to the AODV network. The Client is
simply a regular AODV node which has been configured with the correct setting to
communicate on the network which the Gateway node is attached to. This means
that a client node should have the same DNS settings as a Gateway node. These
setting can usaully be accessed through the netconf program.

The Gateway node will generate a Route Reply to all Route Request which are
not in the AODV subnet. IPTABLES is used to do NAT, allowing AODV nodes to
access the external network. IPTABLES should be installed on the Gateway
node.

After a Client nodes network settings have been correctly configured it is
started using './start.sh'.

Before a Gateway node can be started, its startup script must first be edited.
Edit start_gateway.sh to reflect your current network configuration. Once that
is done you should be ready to go!


 For example:
     Node A - the gatewaying nodes
	  eth0- connected to internet
		IP= 129.6.53.50
	  eth1- WLAN connected to other AODV nodes
		IP= 129.6.230.5


     Node B - AODV node
	  eth0- connected to other AODV nodes
		IP=129.6.230.4

     The AODV subnet in this example would be 129.6.230

Notes:
	The IP addresses for all the interfaces connected to the AODV network must be
in the same subnet.

	Also make sure /proc/sys/net/route/min_delay is set to zero. This is the time
that changes to the routing table are cached before being written. If it is not
zero, crazy things happen... crazy things...
