If you specify v2-MD5, you must also specify a rip-receive-key. Keys are ASCII strings with a maximum
of 31 characters, and must match the other Gateway(s) keys for proper operation of MD5 suppor t.
Ethernet LAN Settings
set ip ethernet A option { on | off }
Enables or disables communications through the designated Ethernet por t in the Gateway. You must
enable TCP/IP functions for an Ethernet por t before you can configure its network settings.
set ip ethernet A address ip_address
Assigns an IP address to the Motorola Netopia® Gateway on the local area network. The IP address you
assign to the local Ethernet inter face must be unique on your network. By default, the Motorola Neto-
pia® Gateway uses 192.168.1.254 as its LAN IP address.
set ip ethernet A broadcast broadcast_address
Specifies the broadcast address for the local Ethernet inter face. IP hosts use the broadcast address to
send messages to ever y host on your network simultaneously.
The broadcast address for most networks is the network number followed by 255. For example, the
broadcast address for the 192.168.1.0 network would be 192.168.1.255.
set ip ethernet A netmask netmask
Specifies the subnet mask for the local Ethernet inter face. The subnet mask specifies which bits of the
32-bit binar y IP address represent network information. The default subnet mask for most networks is
255.255.255.0 (Class C subnet mask).
set ip ethernet A restrictions { none | admin-disabled }
Specifies whether an administrator can open a telnet connection to a Motorola Netopia® Gateway over
an Ethernet inter face (
A = the LAN) to monitor and configure the unit.
The admin-disabled argument prevents access to the device via telnet, web, and SNMP.
By default, administrative restrictions are none on the LAN, but admin-disabled is set on the WAN.
This means that, by default, an administrator can open, for example, a telnet connection from the LAN,
but not the WAN.
set ip ethernet A rip-send { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-
casts to adver tise its routing tables to other Gateways on your network. RIP Version 2 (RIP-2) is an
extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful infor-
mation in the RIP packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 suppor ts sev-
eral additional features, including inclusion of subnet masks in RIP packets and implementation of
multicasting instead of broadcasting (which reduces the load on hosts which do not suppor t routing
protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring
an authentication key when routes are adver tised.
