Configure PPP mappings
ÉWeb
1. Go to Configuration >Network >Interfaces >Advanced >PPPMappings.
2. Associate functions with PPP interfaces. The PPP Mappings page contains two columns of as
many interfaces as are supported by the router (this varies between models). Each row in the
column contains a drop-down list box for selecting functions to associate with each PPP
instance. The PPP instance number is the left-most column. For example, to assign a W-WAN
interface to PPP instance 3, select Mobile SIM1 or SIM2 from the drop-down box to the right
of instance 3. If a W-WAN interface is fitted to the router, this is the default mapping.
