Creating an IP interface for PPP
An IP interface is required to link a PPP connection to the IP context. The IP interface must apply a network
address port translation (NAPT) if the PPP service provider only offers a single IP address and not an IP sub-
net, or if the IP addresses on the LAN shall be private and hidden behind a public IP address (see 11,

net, or if the IP addresses on the LAN shall be private and hidden behind a public IP address (see 11,
on page 132 for more information about NAPT).

Only defines what route is entered into the IP
routing table:

no point-to-point: A route to the subnet
defined by IP address of the PPP interface
(assigned by the PPP peer) is entered into
the routing table. The class of the IP address
determines the size of the subset.
