Computers can connect to the ZyXEL Device’s LAN ports (or wirelessly).
Figure 1
ZyXEL Device’s Internet Access Application
You can also configure firewall on the ZyXEL Device for secure Internet access.
When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network. This means that probes from the
outside to your network are not allowed, but you can safely browse the Internet
and download files.
Use egress queuing and policy routing to efficiently manage traffic on your
network by giving priority to certain types of services, traffic and/or to particular
computers. For example, you could make sure that the ZyXEL Device gives voice
over Internet calls high priority, and/or limit bandwidth devoted to excessive file
downloading.
1.2.2
VoIP Features
You can register up to 2 SIP (Session Initiation Protocol) accounts and use the
ZyXEL Device to make and receive VoIP telephone calls:
