For enhanced security, the NetGuardian G5 has two 10/100 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.
There is no routing between Net 1 and Net 2, this ensures that both connections are independent of
each other. By default, outbound data traffic from the NetGuardian 832A will be sent over Net 2. Only
outbound data that is specifically directed to Net 1, usually the Company's LAN, will be sent to Net 1. To
use both network interfaces, be sure Net1 and Net2 are on separate Subnet Masks.
To use only one of the network interfaces, set either Net1 or Net2 to IP address being used and set the
unused network IP subnet and gateway to 255.255.255.0. If your NetGuardian has the 4-port hub build
option, use Net2, which is connected to the Hub. 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.
