EST P/N AA107-Horizon
Router Modes (AP Router and AP Masquerade)
The ESTeem Horizon can be configured as a network router or network firewall between the Ethernet LAN connection
and the wireless network of remote locations. The router modes are used to limit the network traffic from a busy
Ethernet network connection to only those specific IP address used on the wireless network (see Figure 4). The
Ethernet router mode (AP Router) will allow bi-directional communication from the Ethernet LAN connection to the
wireless network. The Ethernet firewall mode (AP Masquerade) will allow Ethernet devices in the wireless network
to request information from the Ethernet LAN network and receive a response, but no traffic can be generated from
the Ethernet LAN side.
Example Applications
Wireless Ethernet networks connected to large company or plant Ethernet LAN networks (AP Router)
Wireless Ethernet networks with a requirement for network isolation from the plant or company network
(AP Router)
Shared Ethernet connection to direct Internet service (DSL, Cable, T1, etc.) (AP Masquerade)
Applications Where Ethernet Router Mode Not Used
Mobile applications (see Mobile Clients)
Simple network connections only using a single IP network subnet (see Ethernet Bridge modes)
