at the other end of the connection conver ts the analog signal back to a digi-
tal signal.
MRU. Maximum Receive Unit. The maximum packet size, in bytes, that a
network inter face will accept.
MSSID. Multiple Service Set IDentifier. Unique identifiers of data sent over a
wireless connection that act as passwords when wireless devices tr y to join
wireless networks. An SSID differentiates one wireless network from
another, so all access points and all devices attempting to connect to a spe-
cific network must use the same SSID. Netopia Gateways suppor t up to four
SSIDs.
SSIDs are also sometimes referred to as Network Names because they are
names that identify wireless networks.
MTU. Maximum Transmission Unit. The maximum packet size, in bytes, that
can be sent over a network inter face.
MULTI-LAYER. The Open System Interconnection (OSI) model divides net-
work traffic into seven distinct levels, from the Physical (hardware) layer to
the Application (software) layer. Those in between are the Presentation, Ses-
sion, Transpor t, Network, and Data Link layers. Simple first and second gen-
eration firewall technologies
inspect between 1 and 3 layers of the 7 layer
model, while our SMLI engine inspects layers 2 through 7.

NAK. Negative acknowledgment. See ACK.
Name. The Name parameter refers to the name of the configured tunnel.
This is mainly used as an identifier for the administrator. The Name parame-
ter is an ASCII and is limited to 31 characters. The tunnel name is the only
IPSec parameter that does not need to match the peer gateway.
NCP. Network Control Protocol.
Negotiation Method. This parameter refers to the method used during the
Phase I key exchange, or IKE process. SafeHarbour suppor ts Main or
