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.
The NetGuardian G5 unit with the integrated switch comes with two physical 10/100 Ethernet ports. The
standard G5 unit without the switch comes equipped with two physical Ethernet ports. The switch is internally
tied to NET2 and any one of its four ports can be used for uplink.
Build Option: NetGuardian G5 with GigE Fiber Top Board
If your NetGuardian G5 was ordered with the GigE Fiber top board, 1000Base SFP interface must be used. The
SFP ports are internally connected to the 4 port switch and NET 2.
