Chapter 10 Network Address Tran slation NBG-416N User’s Guide 11 2 Note: Y ou must create a firewall rule in additio n to sett ing up NA T , to allow traf fic from the W AN to be forwarded thro ugh the NBG-416N. 10.2 What Y ou Can Do •U s e t h e General screen to enable NA T and set a default server ( Section 10.
Chapter 10 Network Addre ss Translation NBG-416N User’s Guide 11 3 Note: NA T never changes the IP address (eit her local or globa l) of an outside host.
Chapter 10 Network Address Tran slation NBG-416N User’s Guide 11 4 so incoming reply packets can have their original v alues restored. The f ollowing figure illustr ates this. Figure 73 How NA T Works 10.3 General NA T Screen Use this screen to enable NA T and set a default server .

Appendix A IP Addresses and Subnetting NBG-416N User’s Guide 163 Subnet masks are expressed in dotted decimal nota tion just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.
Appendix A I P Addresses and Subnetting NBG-416N User’s Guide 164 Subnetting Y ou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.
Appendix A IP Addresses and Subnetting NBG-416N User’s Guide 165 Figure 1 10 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits , so each sub-network has a maximum of 2 7 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’ s address itself , all ones is the subnet’ s broadcast address).
Appendix A I P Addresses and Subnetting NBG-416N User’s Guide 166 Example: Eight Subnet s Similarly , use a 27-bit mask to create eight subn ets (000, 001, 010, 011, 100, 101, 110 and 11 1). The following table shows IP address last octet values for each subnet.
