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.
Since the VLAN interface is on LAN, we have used a private IP address.

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# show ip nat statistics
