Create custom Bridges and Vlan interfaces
ref.769301 allows setup of custom bridges and VLAN interfaces. The following features are supported:
• VLAN creation over Coax, wireless and Ethernet interfaces.
• Bridge connection (Bridges) between physical interfaces (Ethernet, Coaxial or Wifi) and VLAN
interfaces
• PPPoE with VLAN: Support for packet routing through a PPPoE link over VLAN interface
• DHCP Client with VLAN: Support for packet routing through a VLAN interface configured with a
DHCP client.
System Interfaces description
Ref.769301 has four interfaces:
• Coaxial interface eth0: This interface is connected to the coaxial network. Internally this interface
is called eth0 and is the interface connected to the CoaxData master device.
• Ethernet LAN Interface eth1: This interface represents the device's Ethernet LAN ports. This
interface is connected internally to an internal switch that provides access to the three Ethernet
ports on the device.
• Wireless interface ath0: This interface represents the device's wireless access point. There is
typically a single VAP CoaxData-DoC-Wifi (ath0) in AP mode. The device would accept the
configuration of more VAPs, that internally would be named ath0, ath1, etc.
• Default Bridge br0: This bridge is created in the device between the Ethernet (eth1) and Wireless
(ath0) interfaces to provide ethernet bridge between the Ethernet and Wireless. The IP
configuration of the LAN (172.16.0.1) and the DHCP server operates on this interface.
Operation Modes
ref.769301 has two modes of operation
Router Mode
In this mode there are two networks.
WAN (eth0) network is connected to
the Coaxial network and LAN (br0)
network is connected to the Wireless
(ath0) and Ethernet (eth1) interfaces.
In this mode the device acts as a
router, routing packets from the
internal network (LAN) to the external
WAN.
AP Mode or Bridge Mode: In this
mode there is no WAN interface and
all interfaces (Coaxial: eth0, Wifi: ath0
and Ethernet eth1) are interconnected
to the LAN (br0), allowing a layer 2
communication between all interfaces.
In this mode the device works as a
transparent switch, relaying packets
between the different interfaces.
