Cisco Systems 520 series manual Configuration Example, Router# show ip nat statistics

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-configcommand.

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:
