Appendix D IP Addresses a nd Subnetti ng P-2304R-P1 Series User’s Guide 252 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 c ompany network for security reasons.
Appendix D IP Addresses and Subnetting P-2304R-P 1 Series Us er’s Guide 253 Figure 152 Subnetting Example: Af ter 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).

P-2304R-P 1 Series Us er’s Guide 259 A PPENDIX F NA T NA T Overview NA T (Network Address Translation - NA T , RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outg oing packet, used within one network is changed to a different IP address known w ithin another network.
Appendix F NAT P-2304R-P1 Series User’s Guide 260 What NA T Does In the simplest form, NA T changes the sour ce IP address in a packet received from a subscriber (the inside local address) to anothe r (the inside global address) before forwarding the packet to the W AN side.
Appendix F NAT P-2304R-P 1 Series Us er’s Guide 261 NA T Application The following figure illustrates a possible NA T application, wher e three inside LANs (logical LANs using IP Alias) behind the ZyXEL Devi ce can communicate with three distinct W AN networks.
Appendix F NAT P-2304R-P1 Series User’s Guide 262 " Port numbers do not change for One-to -One and Many One-to-One NA T mapping types. The following table summarizes these types. NA T T ypes This section discusses the following NA T types th at may be implemented on a router in front of the ZyXEL Device.
Appendix F NAT P-2304R-P 1 Series Us er’s Guide 263 The following table summarizes how these NA T ty pes handle outgoing a nd incoming pack ets. Read the following sections fo r more details and examples. The exampl es in these NA T type sections describe NA T translatio n between internal (private) and external (public) IP addresses.
Appendix F NAT P-2304R-P1 Series User’s Guide 264 Restricted Cone NA T As in full cone NA T , a restricted cone NA T router maps all o utgoing packets from an in ternal IP address and port to a single IP address and port on the external network.
