9.5 Using PAT over PPP with a minimum of official IP addresses
This is another example of a local network that only uses private addresses.
A PPP link connects your site to the Internet Service Provider. At your site a Telindus 1031 Router is
installed. You only received 1 official IP address from the ISP. To reduce the number of official IP
addresses, the ISP also uses private IP addresses on the PPP link. The central router its routing table
has a host route to its PAT address per customer.
The configuration of the Telindus 1031 Router in CLI format is as follows:
