As a device on the Internet, a Motorola Netopia® Gateway requires an IP address in order 
to send or receive traffic.

The IP traffic sent or received have an associated application por t which is dependent on 
the nature of the connection request. In the IP protocol standard the following session 
types are common applications:

By receiving a response to a scan from a por t or series of por ts (which is the expected 
behavior according to the IP standard), hackers can identify an existing device and gain a 
potential opening for access to an internet-connected device.

To protect LAN users and their network from these types of attacks, BreakWater offers 
three levels of increasing protection. 

The following tables indicate the 

state of ports associated with session types, both on 

the WAN side and the LAN side of the Gateway.
