1. LocatetheresetbuttononthePeplinkBalanceunit.
2. Withapaperclip,pressandkeeptheresetbuttonpressedforatleast10


ImportantNote
Allusersettingswillbelostafterrestoringthefactorydefaultsettings.Regularbackupofconfiguration

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:
