Port-based VLAN is a group of ports on an Ethernet or Virtual Aps of Wired or
Wireless Gateway that forma logical LAN segment. Following is an example. In
SMB or a company, administrat or schemes out 4 segments, Lobby,
Lab&Servers, Office and VoIP&IPTV. In a Wireless Gateway, administrator can
configure Lobby segment with VLAN ID4. The VLAN group includes Port-4 and
VAP-8(SSID: Guest) with NAT mode and DHCP-3 server equipped. He also
configure Lab&Servers segment with VLAN ID3. The VLAN group includes
Port-3 with NAT mode and DHCP-2 server equipped. However, he configure
Office segment with VLAN ID 2. The VLAN group includes Port-2 and VAP-1
(SSID: Staff) with NAT mode and DHCP-1 server equipped. At last, administrator
also configure VoIP&IPTV segment with VLAN ID11. The VLAN group includes
Port-1 with bridge mode to WAN interface as shown at
following diagram.
Above is the general case for 4 Ethernet LAN ports in the gateway. But the
device has only one Ethernet LAN port. So, there is only one VLAN group in the
device. But it also supports two different kinds of application for the Port-based
VLAN tagging, NAT or Bridge.

Tag-based VLAN Tagging for Location-free Departments
Tag-based VLAN function can group Ethernet port, Port-1, and WiFi Virtual
Access Points, VAP-1 ~ VAP-8, together with different VLAN tags for deploying
department subnets in Intranet. All packet flows can carry with different VLAN
tags even at the same physical Ethernet port for Intranet. These flows can be
directed to different destination because they have differentiated tags. The
approach is very useful to group some hosts in different geographic location to
be a same department.
Tag-based VLAN is also called a VLAN Trunk. The VLAN Trunk collects all
packet flows with different VLAN IDs from Router device and delivers them in
the Intranet. VLAN membership in a tagged VLAN is determined by VLAN ID
information within the packet frames that are received on a port. Administrator
can further use a VLAN switch to separate the VLAN trunk to different groups
based on VLAN ID. Following is an example. In SMB or a company,
administrator schemes out 3 segments, Lobby&Restaurant, Lab & Meeting
Rooms and Office. In a Security VPN Gateway, administrator can configure
Lobby&Restaurant segment with VLAN ID12. The VLAN group is equipped with
DHCP-3 server to construct a 192.168.12.x subnet. He also configure
Lab&Meeting Rooms segment with VLAN ID 11. The VLAN group is equipped
with DHCP-2 server to construct a 192.168.11.x subnet for Intranet only. That is,
any client host in VLAN 11 group can’t access the Internet. However, he
configures Office segment with VLAN ID 10. The VLAN group is equipped with
DHCP-1 server to construct a 192.168.10.x subnet. In this example, VLAN 10
and 12 groups can access the Internet as following diagram.
