IPSec VPN

This allows you to establish a secure Virtual Private Network (VPN)

tunnel to connect with business partners and branch offices using data

encryption and the Internet without the expense of leased site-to-site

lines. The NBG420N VPN is based on the IPSec standard and is fully

interoperable with other IPSec-based VPN products.

Bandwidth Management

You can efficiently manage traffic on your network by reserving

bandwidth and giving priority to certain types of traffic and/or to particular

computers.

Wireless LAN Scheduler

You can schedule the times the Wireless LAN is enabled/disabled.

Time and Date

Get the current time and date from an external server when you turn on

your NBG420N. You can also set the time manually. These dates and

times are then used in logs.

Port Forwarding

If you have a server (mail or web server for example) on your network,

then use this feature to let people access it from the Internet.

DHCP (Dynamic Host

Configuration Protocol)

Use this feature to have the NBG420N assign IP addresses, an IP

default gateway and DNS servers to computers on your network.

Dynamic DNS Support

With Dynamic DNS (Domain Name System) support, you can use a

fixed URL, www.zyxel.com for example, with a dynamic IP address. You

must register for this service with a Dynamic DNS service provider.

IP Multicast

IP Multicast is used to send traffic to a specific group of computers. The

NBG420N supports versions 1 and 2 of IGMP (Internet Group

Management Protocol) used to join multicast groups (see RFC 2236).

IP Alias

IP Alias allows you to subdivide a physical network into logical networks

over the same Ethernet interface with the NBG420N itself as the

gateway for each subnet.

Logging and Tracing

Use packet tracing and logs for troubleshooting. You can send logs from

the NBG420N to an external syslog server.

PPPoE

PPPoE mimics a dial-up Internet access connection.

PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of

data through a Virtual Private Network (VPN). The NBG420N supports

one PPTP connection at a time.

Universal Plug and Play

(UPnP)

The NBG420N can communicate with other UPnP enabled devices in a

network.
