Netopia 2200 Set ip dsl vccn netmask netmask, Set ip dsl vccn restriction admin-disabled none

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 dsl vccn netmask netmask

Specifies the subnet mask for the TCP/IP network connected to the virtual circuit. The sub- net mask specifies which bits of the 32-bit binary IP address represents network informa- tion. The default subnet mask for most networks is 255.255.255.0 (Class C subnet mask).

set ip dsl vccn restriction { admin-disabled none }

Specifies restrictions on the types of traffic the Netopia Gateway accepts over the DSL vir- tual circuit. The admin-disabledargument means that access to the device via telnet, web, and SNMP is disabled. RIP and ICMP traffic is still accepted. The none argument means that all traffic is accepted.

set ip dsl vccn addr-mapping { on off }

Specifies whether you want the Netopia Gateway to use network address translation (NAT) when communicating with remote routers. Address mapping lets you conceal details of your network from remote routers. It also permits all LAN devices to share a single IP address. By default, address mapping is turned “On”.

set ip dsl vccn rip-send { off v1 v2 v1-compat v2-MD5 }

Specifies whether the Netopia Gateway should use Routing Information Protocol (RIP) broadcasts to advertise its routing tables to other routers. RIP Version 2 (RIP-2) is an extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algo- rithms, RIP-2 supports several 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 support routing protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.

Depending on your network needs, you can configure your Netopia Gateway to support RIP- 1, RIP-2, or RIP-2MD5.
