12) SU Access to the Public Network (NAT)
The NAT (Network Address Translation) feature lets hosts on the Ethernet side of the SU transparently access
the public network through the Base Station. All hosts in the private network can have simultaneous access to the
public network.
Note: The NAT tab is available for SUs in Routing mode only. The SU supports NAPT (Network Address Port
Translation) where all private IP addresses are mapped to a single public IP address, and does not
support Basic NAT (where private IP addresses are mapped to a pool of public IP addresses).
Both dynamic mapping (allowing private hosts to access hosts in the public network) and static mapping
(allowing public hosts to access hosts in the private network) are supported.
• In dynamic mapping, the SU maps the private IP addresses and its transport identifiers to transport
identifiers of a single Public IP address as they originate sessions to the public network. This is used only
for outbound access.
• Static mapping is used to provide inbound access. The SU maps a private IP address and its local port to
a fixed public port of the global IP address. This is used to provide inbound access to a local server for
hosts in the public network. Static port mapping allows only one server of a particular type. Up to 1000
ports (500 UDP and 500 TCP) are supported.
