NTERFACES

Each NetScreen-200 device provides ethernet interfaces for access and connectivity. In 
addition, there are logical (non-physical) interfaces that perform special Layer-2 or 
management functions.

The configurable interfaces available on a NetScreen-200 Series device are as follows:

ethernetn specifies a physical ethernet interface, denoted by a physical port 
(n) on the module. Although each interface is bound to a security zone by 
default, you can bind it to another zone as required.

• ethernet1 Bound to the Trust security zone by default. Connect this 

interface using a twisted pair cable with RJ-45 connectors. 

• ethernet2 Bound to the DMZ security zone by default. Connect this 

interface using a twisted pair cable with RJ-45 connectors.

• ethernet3 Bound to the Untrust security zone by default. Connect this 

interface using a twisted pair cable with RJ-45 connectors.

• ethernet4 On NetScreen-204, bound to HA zone by default. On NetScreen-

208, bound to the Null zone by default.

• ethernet5 through ethernet7 Bound to Null zone by default.

• ethernet8 Bound to the HA zone by default.

vlan1 specifies a logical interface used for management and for VPN traffic 
termination while the NetScreen device is in Transparent mode.

tunnel.n specifies a logical tunnel interface. This interface is for VPN traffic.
