CONFIG Commands

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 binary IP address represent network information. The default sub-

net 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 Netopia Gateway

over the Ethernet inter face to monitor and conﬁgure the unit. The admin-disabled argu-

ment means that access to the device via telnet, web, and SNMP is disabled. On the WAN

port, you can enable or disable administrator access or specify that the WAN port can only

be used for administrative trafﬁc. By default, administrative restrictions are off on the LAN,

but Admin-Disabled is set for the WAN, meaning an administrator can open a telnet con-

nection.
