Configuring Static Address Translation
Static address translation creates a one-to-one mapping of an unregistered local
host address to a registered global address. Static address mappings can be used
to:
• Preserve a translation entry.
• Create a connection from a host on the global network to a host on the local
network.
A static address translation does not time out when there is no traffic on the
interface. The translation remains fixed until you disable or delete it.
You can assign static address mappings from the same global address allocation
pool used for dynamic address translations. The router will not use the reserved
address for a dynamic allocation. However, if you try to configure a static address
mapping using a global IP address that is currently being used for a dynamic
translation, you receive an error message.
Adding a Static Address Mapping
Use the BCC or Site Manager to add a static address mapping.
Using the BCC
To add a static address mapping, navigate to the global NAT prompt (for example,
box; ip; nat
) and enter:
static-map
<local_address>
/
<global_address>
local_address
is an unregistered local address of a host in your network. Enter the
local address in dotted-decimal notation.
global_address is the registered global address that you want to map to the local
address. Enter a valid global IP address in dotted-decimal notation.
