Interfaces to Change During Initial Configuration
The default IP address and subnet mask settings for NetScreen-ISG 2000 interfaces are
0.0.0.0 and 0.0.0.0, respectively. The exception is MGT, a special interface used only for
device management. The default IP address and subnet mask settings for the MGT
interface are 192.168.1.1 and 255.255.255.0, respectively.
• For all operational modes, it is advisable to change the IP address and subnet
mask for the MGT interface, and to use it exclusively for out of band
management.
• To access the vlan1 interface in Transparent mode, you must change the IP
address and subnet mask of vlan1 to match your current network.
• In Transparent mode, only the MGT and vlan1 interfaces may have a new IP
address and subnet mask. All others must keep their default IP address and
subnet mask settings (0.0.0.0 and 0.0.0.0, respectively).
• In Route mode (with or without NAT), at least two Ethernet interfaces must
have new IP addresses and subnet masks.

ETWORK
The NetScreen-ISG 2000 has four interface module bays, which can contain the following
types of modules:
• 10/100 Mbps interface module, for 10/100 Base-T connections (4 and 8 ports)
• Mini-GBIC interface module, for fiber-optic connections (2 ports)
The type of network used by your organization determines the kind of interface needed to
connect the NetScreen-ISG 2000. (For more information on interface modules, see
“Interface Modules” on page 6 .)
Note: For more information on setting IP addresses, see “Setting Port and Interface IP
Addresses” on page 31
Note: Because of the wide variety of available routers, hubs, and switches, the cabling
configuration presented here might not satisfy your network connection requirements. If
the cabling suggested in this chapter does not work, try other cable configurations until a
link light indicates an active link.
