In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the NBG334S.
Page 105: Figure 55 Any Ip Example
IP routing table is defined on IP Ethernet devices (the NBG334S) to decide which hop to use, to help forward data along to its specified destination. The following lists out the steps taken, when a computer tries to access the Internet for the first time through the NBG334S.

Page 119: 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 NBG334S to record Jane’s computer IP address. The NBG334S associates Jane's computer IP address with the "incoming" port range of 6970-7170.

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 NBG334S. 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.

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. NBG334S User’s Guide...
Page 224: 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. NBG334S User’s Guide...
