This section provides an example for configuring a firewall as a DHCP client that applies to a DHCP server (carrier device) for an IPv4 address to access the Internet.
For details about how to access the Internet through IPv4 PPPoE on the web UI, see Example 2: Accessing the Internet Using PPPoE in the quick configuration guide. Click here to obtain the latest quick configuration guide.
This section provides an example for the device, working as a PPPoE client, to obtain an IP address by dialing up to the carrier's server through PPPoE for Internet access.
In the networking, users belong to different VLANs. To implement the communication between devices in different VLANs, you can assign IP addresses to VLANIF interfaces.
This section provides an example for configuring VLANs on Layer-3 subinterfaces to allow the VLANs to communicate. As the number of physical interfaces is limited, you can configure multiple subinterfaces on a physical interface. Each subinterface belongs to a specific VLAN. VLANs can communicate with each other on a single physical interface.
This section provides an example for configuring VLAN trunk interfaces when VLANs are deployed across devices. Data of a specific VLAN is identified by an 802.1q tag and is transmitted over trunk links formed by connected trunk interfaces.
