Appendix B.Routing under DHCP, Static IP, and PPPoE
The information in this appendix applies only to situations where the Peplink Balance operates a WAN
connection under DHCP, Static IP, or PPPoE.
B.1 RoutingViaNetworkAddressTranslation(NAT) 
When the Peplink Balance is operating under NAT mode, the source IP addresses of outgoing IP packets
are translated to the WAN IP address of the Peplink Balance. With NAT, all LAN devices share the same
WAN IP address to access the Internet (i.e., the WAN IP address of the Peplink Balance).
Operating the Peplink Balance in NAT mode requires only one WAN (Internet) IP address. In addition,
operating in NAT mode also has security advantages because LAN devices are hidden behind the Peplink
Balance. They are not directly accessible from the Internet and hence less vulnerable to attacks.
The following figure shows the packet flow in NAT mode:
