Chapter 3
Configuring PPP over Ethernet with NAT
Configuration Example
Configuration Example
The following configuration example shows a portion of the configuration file for the PPPoE scenario
described in this chapter.
The VLAN interface has an IP address of 192.168.1.1 with a subnet mask of 255.255.255.0. NAT is
configured for inside and outside.
Note
Since the VLAN interface is on LAN, we have used a private IP address.
Note
Commands marked by “
(default)
” are generated automatically when you run the
show running-config
command.
!
vpdn enable

Verifying Your Configuration
Use the
show ip nat statistics
command in privileged EXEC mode to verify the PPPoE with NAT
configuration. You should see verification output similar to the following example:
Router#
