What Is Vlan - ZyXEL Communications P-793H v2 Support Notes

For forwarding the inbound IPSec ESP tunnel, A 'Default' server set is required.
You could configure it in Web Configurator, Advanced Setup, Network -> NAT
-> Port Forwarding -> Default Server Setup:
It is because SUA makes your LAN appear as a single machine to the outside
world. LAN users are invisible to outside users. So, to make an internal server
for outside access, we must specify the service port and the LAN IP of this
server in Web configurator. Thus SUA is able to forward the incoming packets to
the requested service behind SUA and the outside users access the server
using the P-793H v2's WAN IP address. So, we have to configure the internal
IPsec client as a default server (unspecified service port) when it acts a server
gateway.

22. What is VLAN?

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned
into multiple logical networks. Stations on a logical network belong to one group
called VLAN Group. A station can belong to more than one group.
The stations on the same VLAN group can communicate with each other. With
VLAN, a station cannot directly talk to or hear from stations that are not in the
same VLAN group(s); the traffic must first go through a router.
23. 802.1Q/1P
In order to resolve the limitation of port based VLAN, this framework of
802.1Q/1P feature is proposed. The key concepts are as below:
 One VLAN group is treated as "individual" device, just like there are many
virtual devices on one physical device.
 Each LAN port, and PVC is similar to a VLAN switch port. Each can be
grouped into any 802.1Q VLAN group and individually configured as tagged
or untagged.
 The PVID of Each LAN port, and PVC can be individually configured.
 In each VLAN group, it is allowed to have multiple bridge PVCs, route PVCs
or mixed PVCs.
