LAN Connection

For enhanced security, the NetGuardian-16S has two 10BaseT Ethernet ports. Each port has its own separate IP
address and subnet, so you can safely connect one port to your private company LAN and the other to the public
Internet.
Connect the Private Ethernet port to the company LAN.
Connect the Public Ethernet port to the Internet.
By default, outbound data traffic from the NetGuardian-16S will be sent over the Public Ethernet port. Only
outbound data that is specifically directed for the company LAN will be sent over the Private Ethernet port.
Both ports are standard RJ45 ports that take standard RJ45 Ethernet cables. If the IP connection is OK, the LNK
LED will light SOLID GREEN when the cable is connected.
The pinout for the Ethernet ports is shown in Figure 5.4.2, above.

Telco Connection

The rear panel telco jack (see Figure 5.5.1) connects the NetGuardian-16S internal modem to a standard phone
line for dial-up access and pager alarm notification.
