MODEL 195Es CONFIGURATION MODES
The Model 195Es can be configured for multiple
modes of operation without any changes to the
hardware:
Access Point Modes
1. Access Point Bridge Mode. When the
Model 195Es is configured as an Access
Point it will provide a wireless bridge
between hardwired Local Area Network
(LAN) networks or individual devices and
simultaneously create a wireless canopy for
the Model 195Es modems in client mode.
Multiple Access Point Bridge modems can be
physically connected to the same network
(LAN) or through a radio link using the
Access Point Repeater mode to provide
overlapping, seamless Ethernet
communication for mobile devices. The
ESTeem Model 195Es in Access Point Bridge mode will pass all network traffic between connected devices including global
network broadcasts. See Figure 1.
2. Access Point Router Mode. In this mode the ESTeem Model 195Es will function as a router between the wired Ethernet
network (connect to the 195Es’ Ethernet port) and the wireless network 195Es’ in repeater peer mode. As in all standard
router configurations, the wireless and wired Ethernet networks will need to be on separate subnets. To communicate from
the wired Ethernet network to devices on the wireless network, a separate router (in addition to the Model 195Es) is required.
The 195Es in Access Point Router mode will pass network traffic for connected devices but will block global network
broadcasts from the wired network. This mode of operation should be used instead of the Access Point Bridge mode when a
separation between networks is required or the ESTeem is connected to larger LAN Networks that will continuously send
global network broadcasts (Figure
2).
3. Access Point Masquerade Mode.
The Access Point Masquerade
mode is a special use of the Access
Point mode where the Model 195Es
will connect clients into a single
static IP address on a wired
network. Data requests from the
wireless network will be processed
through the Access Point
Masquerade 195Es, but any request
from the wired Ethernet network to
devices on the wireless network
will be rejected similar to the
operation of a “firewall”. The
195Es will hide all the IP addresses
connected on the wireless link.
You should use this mode of
