MODEL 195Ed CONFIGURATION MODES
The Model 195Ed 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 195Ed is configured as an Access
Point it will provide a wireless bridge from a
hardwired Local Area Network (LAN) to
other Model 195Ed modems in client modes.
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 195Ed 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 195Ed will function as a router between the wired Ethernet
network, connect to the 195Ed’s Ethernet port, and the wireless network of other 195Ed’s 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 (or the Model 195Ed configured as a
router) is required. The 195Ed 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 195Ed will connect
multiple 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 195Ed, 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 195Ed
will hide all the IP addresses
connected on the wireless link. You
should use this mode of operation if
Model 195Ed is connected directly to
the Internet with a static IP address
