Appendix A. Restoration of Factory Defaults
To restore the factory default settings on a Peplink Balance unit, perform the following:
For Balance models with a reset button:
1. Locate the reset button on the Peplink Balance unit.
2. With a paperclip, press and keep the reset button pressed.
Note: There is a dual function to the reset button.
Hold for 5-10 seconds for admin password reset (green status light starts blinking)
Hold for more than 10 seconds for a factory reset ( until all WAN/LAN port lights start blinking).
For Balance/MediaFast models with an LCD menu:
Use the buttons on front panel to control the LCD menu to go to Maintenance>Factory Defaults,
and then choose Yes to confirm.
Afterwards, the factory default settings will be restored.
Important Note
All user settings will be lost after restoring the factory default settings. Regular backup of configuration
parameters is strongly recommended.
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:
