Page 105: Homeplug Av
HomePlug AV powerline adapters in your network communicate with each other by sending and receiving information over your home’s electrical wiring. The NBG-318S plugs into an ordinary outlet to create a new network which can extend to any other electrical outlet in any room of a house.
Page 106: Privacy And Powerline Adapters
The HomePlug AV standard uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline adapters. For the NBG-318S and powerline adapters to communicate with each other they all need to use the same Network Membership Key (NMK). Otherwise, they cannot unscramble the encrypted data sent in the powerline network.
Page 107: Setting Up Multiple Powerline Networks
You now have two private networks on your powerline circuit. Information is not shared between the two networks as only powerline adapters with the same password can communicate with each other. The following figure shows two private powerline networks on the same electrical circuit. NBG-318S User’s Guide...

TCP/IP configuration at start-up from a server. You can configure the NBG- 318S as a DHCP server or disable it. When configured as a server, the NBG-318S provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else the computer must be manually configured.
Page 112: Dhcp Server Advanced Screen
The NBG-318S passes a DNS (Domain Name System) server IP address (in the order you specify here) to the DHCP clients. The NBG-318S only passes this information to the LAN DHCP clients when you select the Enable DHCP Server check box. When you clear the Enable DHCP Server check box, DHCP service is disabled and you must have another DHCP sever on your LAN, or else the computers must have their DNS server addresses manually configured.

Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG-318S records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger"...
Page 121: Two Points To Remember About Trigger Ports
1 Jane requests a file from the Real Audio server (port 7070). 2 Port 7070 is a “trigger” port and causes the NBG-318S to record Jane’s computer IP address. The NBG-318S associates Jane's computer IP address with the "incoming" port range of 6970-7170.
Page 122: Figure 68 Network > Nat > Advanced
Each NAT session establishes a corresponding firewall session. Use this field to limit the number of NAT/firewall sessions each client computer can establish through the NBG-318S. If your network has a small number of clients using peer to peer applications, you can raise this number to ensure that their performance is not degraded by the number of NAT sessions they can establish.
Page 123 Incoming is a port (or a range of ports) that a server on the WAN uses when it sends out a particular service. The NBG-318S forwards the traffic with this port (or range of ports) to the client computer on the LAN that requested the service.

Each remote node specifies only the network to which the gateway is directly connected, and the NBG-318S has no knowledge of the networks beyond. For instance, the NBG-318S knows about network N2 in the following figure through remote node router R1. However, the NBG- 318S is unable to route a packet to network N3 because it doesn't know that there is a route through the same remote node router R1 (via gateway router R2).

Page 212 Internet, especially peer-to-peer applications. 2 Check the signal strength. If the signal strength is low, try moving the NBG-318S closer to the AP if possible, and look around to see if there are any devices that might be interfering with the wireless network (for example, microwaves, other wireless networks, and so on).
Page 213: Resetting The Nbg-318S To Its Factory Defaults
23.4 Resetting the NBG-318S to Its Factory Defaults If you reset the NBG-318S, you lose all of the changes you have made. The NBG-318S re- loads its default settings, and the password resets to 1234. You have to make all of your changes again.
Page 214: Homeplug Av Troubleshooting
3 Make sure that all your powerline adapters are HomePlug AV. Check the package it came in or ask your vendor. This NBG-318S can not detect earlier versions of HomePlug powerline adapters such as HomePlug 1.0 or 1.0.1. (Although they can coexist on the same electrical wiring without interfering with each other.)

Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal. The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. NBG-318S User’s Guide...
Page 232: Figure 131 Network Number And Host Id
Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes. NBG-318S User’s Guide...
Page 233: Table 99 Subnet Masks
For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations.
