Networks take some time in order to plan and implement correctly.

There are many ways to configure your network. You may want to take

some time to determine the best network set-up for your needs.

Introduction to Virtual Private Networking

Virtual Private Networking (VPN) uses a publicly wired network (the

Internet) to securely connect two different networks as if they were the same

network. For example, an employee can access the corporate network from

home using VPN, allowing the employee to access files and printers. Here

are several different implementations of VPN that can be used.

Point-to-Point Tunneling Protocol (PPTP)

PPTP uses proprietary means of connecting two private networks over the

Internet. PPTP is a way of securing the information that is communicated

between networks. PPTP secures information by encrypting the data inside

of a packet

IP Security (IPSec)

IPSec provides a more secure network-to-network connection across the

Internet or a Wide Area Network (WAN). IPSec encrypts all communication

between the client and server whereas PPTP only encrypts the data packets.

Both of these VPN implementations are used because there is not a

standard for VPN server software. Because of this, each ISP or business

can implement its own VPN network making interoperability a challenge.

LEDS

M1&M2 System status indicators, Orange. M1 is flashed once per

second to indicate an active system. When the system is busy, M2 lights up.

WAN & LAN Ethernet port indicators, Green. The LED flickers when the

LAN or WAN port is sending or receiving data.

Link/Act. Link status indicators, Green. The LED flickers when the

corresponding port is sending or receiving data

10/100 10/100 status indicators, Green. The LED flickers when the

corresponding port is transmitting or receiving data in 10 or 100Mbps.
