OMMAND EFERENCE
addresses that you configured by using this command. The RAS 1500
maintains a table of active IP addresses on the public network mapped to
user IP addresses on the private network for the connection. Once the
connection to the public network is closed, the information in the table is
dropped and this IP address is free for the next connection. Each time a
user connects to the public network, the next available address from the
contiguous range is assigned, and a new table of mapped addresses is
established by the RAS 1500.
Note: NAT can only be used when the ISP has provided more than one IP
address. The first and last in the contiguous range of ISP-assigned
addresses are "broadcast" addresses and are not available for NAT. The
second address in the contiguous range is reserved for the RAS 1500 and
also is not available for NAT."
Parameter Description
<user_ name> Unique name that you want to assign the connection that uses
Dynamic NAT to map ISP-assigned addresses to connections
on the private network. Limit: 32 ASCII characters.
count Total number of ISP-assigned addresses starting with the
public_pool_start address that is used by the RAS 1500 for
Dynamic NAT mapping.
public_pool_start The first of the contiguous range of IP addresses assigned by
Dynamic NAT mapping.
private_address <ip_address>
public_address <ip_address>
Configures, and associates a name to, a mapping between and IP address
on the private network to a specific ISP-assigned address on the public
network that uses Static NAT.
Example:
add nat static user nats private address 1.1.1.1 public
address 2.2.2.2
statically assigns the private address 1.1.1.1 to the ISP-assigned addresses
address "2.2.2.2" to for Static NAT and names this mapping that uses
Static NAT, "nats". In this case, 1.1.1.1 always connects to 2.2.2.2. In
this example, "nats" is the name given to the mapping between the IP
address on the private network and ISP-assigned address on the public
network configured for this Static NAT.
