Each NetScreen-50 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-50 device are as follows:
Interface Type Description
Ethernet interfaces 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 zone by default. Connect this interface using
a twisted pair cable with RJ-45 connectors.
• ethernet2 Bound to the DMZ zone by default. Connect this interface using
a twisted pair cable with RJ-45 connectors.
• ethernet3 Bound to the Untrust zone by default. Connect this interface
using a twisted pair cable with RJ-45 connectors.
• ethernet4 Bound to HA zone by default.
Layer-2 interfaces vlan1 specifies a logical interface used for management and VPN traffic
termination while the NetScreen device is in Transparent mode.
Tunnel interfaces tunnel.n specifies a logical tunnel interface. This interface is for VPN traffic.
