Internet access through PPPoE configuration examples

 

The following information provides Internet access through PPPoE examples.

 

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of PPPoE.

Network configuration

As shown in Figure 1, Device is deployed at the egress of the enterprise network. The enterprise applies for a PPPoE account with the username as pppoeuser1 and password as 123456 from the ISP. Configure PPPoE for users in the enterprise network to access the Web server with the address www.example.com in the Internet.

Software versions used

This configuration example was created and verified on F9345 of the F1060 device.

Restrictions and guidelines

When the device acts as a DHCP server, for the DHCP clients to obtain IP addresses, you must permit the traffic from the security zone where the DHCP-enabled interfaces reside to the local security zone. In this example, you must permit the traffic from security zone Trust to security zone Local.

Procedures

Configuring Device

1.     Configure PPPoE.

# On the top navigation bar, click System.

# From the navigation pane, select Configuration Wizard > Internet Access. The page as shown in Figure 2 opens.

Figure 2 Internet Access

 

# Select Routing mode, and click Configure. Configure the WAN interface parameters as shown in Figure 3.

Figure 3 WAN interface configuration

 

# Click Next. Configure the LAN interface parameters as shown in Figure 4.

Figure 4 LAN interface configuration

 

# Click Next. Do not make any DMZ interface, security, or WAN acceleration configuration on the page that opens, and click Next to configure flow control.

# Configure the expected bandwidth for the WAN interface according to the bandwidth allocated by the service provider, as shown in Figure 5.

Figure 5 Flow control

 

# Click Next. The Check configuration page as shown in Figure 6 opens.

Figure 6 Check configuration

 

# Verify that the configurations are correct, and click Finish. The PPPoE configuration information is as shown in Figure 7.

2.     Configure a security policy.

After PPPoE is configured, the system automatically creates a security policy named GuideSecPolicy.

# On the top navigation bar, click Policies.

# From the navigation pane, select Security Policies > Security Policies. The Security Policies page as shown in Figure 8 opens.

Figure 8 Security policy configuration page

 

# Select the security policy GuideSecPolicy, and click the icon in the Edit column. Add the source zone Local, and add the destination zones Trust and Local, as shown in Figure 9.

3.     Configure DHCP.

# On the top navigation bar, click Network.

# From the navigation pane, select DHCP > DHCP Address Pools.

# Click the Address Pool Options tab. Configure parameters as shown in Figure 10.

4.     Configure DNS proxy.

# On the top navigation bar, click Network.

# From the navigation pane, select DNS > Advanced Settings. On the page as shown in Figure 11, enable DNS proxy.

Configuring the hosts

# Configure the hosts to automatically obtain IP addresses.

Verifying the configuration

1.     View the address information that a host obtains.
