Tsunami MP-8100 Installation and Management Guide 125
1. Static NAT: Static mapping is used to provide inbound access. The SU maps the public IP address and its transport
identifiers to the private IP address (local host address) in the local network. 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
100 entries are supported in the static port bind table.
2. Dynamic NAT: 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.
NOTE:
• When NAT is enabled, the network on the wireless side of the device is considered Public and the network on the
Ethernet side are considered Private.
• When NAT functionality is enabled, the DHCP Relay and RIP features are not supported. The DHCP Relay Agent
and RIP must be disabled before enabling NAT.
To set the NAT parameters,
1. Click ADVANCED CONFIGURATION > Network > NAT. The NAT screen appears as shown below.
