Network Topology – Example
The user is connected to the internet via a router with public IP w.x.y.z.
His/her private IP subnet is 192.168.1.0/24. The router masquerades
private IPs to its public IP.
The user must authorize users connected to both HotSpots’ Ethernet
interface eth1 and wireless interfaces ath0. This is accomplished by
configuring NETKROM to act as a HotSpot and authenticate users
connected to those interfaces (HotSpot LAN Interfaces).
The authentication is assumed to be handled by the user’s local Radius
Server (IP 192.168.1.00).
NETKROM HotSpot’s WAN Interface in that case is eth0, the one
connected to the router (and Internet).
Hotspot users will be assigned with IPs in the subnet 192.168.0.0/24
To sum up, NETKROM HotSpot should be configured with:
•
WAN interface: eth0, with static IP 192.168.1.3/24
•
LAN Interfaces: eth1 and ath0
•
Gateway: 192.168.1.1 (router’s private IP)
•
DNS: say 65.173.1.1 (obtained from your internet connection)
•
Radius Server: 192.168.1.100 ( let radius secret be “radius_secret”)
•
Dynamic IPs assigned to users: 192.168.0.0/24
Applying this example, network topology will change to:
