5.2 ETHERNET ACCESS
GARD 8000 is delivered with pre-set IP addresses. The front port IP address is fixed, and factory set to
192.168.1.1 with a subnet mask of 255.255.255.0. The rear port IP address is configurable.
The IP Address assigned to the front port is 192.168.1.1 for every GARD 8000 chassis. DO NOT plug
this port into a LAN. You cannot have more than one device with the same address on a network. The
front port is strictly for direct connection to a Laptop PC. The Laptop should have an IP Address on the
same subnet (192.168.1.x) as described below. The front port has no default gateway configured, so it
is not routable. This is done for security purposes.
