PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct
Internet connection if you do not have a router. PPPoE is a dial-up connection. You
need a username and password from your Internet Service Provider (ISP) to set
up the connection.
6.2 The TCP/IP Screen
Use the TCP/IP screen to have the NSA use a dynamic or static IP address,
subnet mask, default gateway and DNS servers.
6.2.1 Jumbo Frames
To use jumbo frames, your LAN must support 1 Gbps transmissions (Gigabit
Ethernet). All of your network devices (computer Ethernet cards and switches,
hubs, or routers) must also support the same size of jumbo frames that you
specify in the NSA.
Note: If you enable jumbo frames on the NSA in a network that does not support
them, you will lose access to the NSA. If this occurs, you will have to restore the
factory default configuration. Push the RESET button on the NSA’s rear panel
and release it after you hear a beep.
In the following example, the NSA has jumbo frames enabled and set to 8KB
frames. This means the computer, notebook computer, and switch must also have
jumbo frames enabled and be capable of supporting 8KB frames.
