The Conductor uses a technique known as Network Address Translation
(NAT) to provides multiple wireless computers with simultaneous access to
the same Internet connection.
(NAT) to provides multiple wireless computers with simultaneous access to
the same Internet connection.
To implement NAT, the Conductor has two IP addresses: one that it uses to
communicate with the ISP’s network and one to communicate with the Sym-
phony wireless network. In addition, the Conductor acts as a DHCP
(Dynamic Host Configuration Protocol) server to automatically assign IP
addresses to its wireless clients.

Note:
If you intend to share a modem on your wireless network, you
must install a Symphony HomeRF adapter in the computer that
will share its attached modem first.

Wireless Network Communicating With An Ethernet Network
If you have an existing Ethernet card installed in one of the wireless comput-
ers, then you may configure this computer to act as a bridge between the wire-
less network and an Ethernet network, as depicted below:

Proxim provides the Symphony Conductor Modem Sharing Software which
allows a computer that has two network interface cards (NICs) installed to act
as an intermediary between two different networks. The Conductor software
transparently links the two networks so that to each node there appears to be
only one network. This function is known as “Transparent Bridging.”

For example, if one network computer has a Symphony HomeRF adapter and
an Ethernet card installed, then it can grant Ethernet access to the other wire-
less computers via the TCP/IP protocol. In this configuration, each computer,
an Ethernet card installed, then it can grant Ethernet access to the other wire-
less computers via the TCP/IP protocol. In this configuration, each computer,
