to send messages to ever y host on your network simulta-
neously.

The broadcast address for most networks is the network num-
ber followed by 255. For example, the broadcast address for 
the 192.168.1.0 network would be 192.168.1.255.

Specifies the subnet mask for the TCP/IP network connected to 
the vir tual circuit. The subnet mask specifies which bits of the 
32-bit binar y IP address represents network information. 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 Cayman Gate-
way accepts over the DSL vir tual circuit. The 

abled argument means that router traffic is accepted but that 
administrative commands are ignored. The 

none argument 

means that all traffic is accepted. RIP and ICMP traffic is still 
accepted. 

Specifies whether you want the Cayman Gateway to use net-
work 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”.
