ZyWALL 2 Plus User’s Guide
Chapter 2 Introducing the Web Configurator 57
Routing Protocol This shows the routing protocol - IP for which the ZyWALL is configured. This field
is not configurable.
Device Mode This displays whether the ZyWALL is functioning as a router or a bridge.
Firewall This displays whether or not the ZyWALL’s firewall is activated.
System Time This field displays your ZyWALL’s present date and time along with the difference
from the Greenwich Mean Time (GMT) zone. The difference from GMT is based
on the time zone. It is also adjusted for Daylight Saving Time if you set the
ZyWALL to use it.
Memory The first number shows how many kilobytes of the heap memory the ZyWALL is
using. Heap memory refers to the memory that is not used by ZyNOS (ZyXEL
Network Operating System) and is thus available for running processes like NAT,
VPN and the firewall.
The second number shows the ZyWALL's total heap memory (in kilobytes).
The bar displays what percent of the ZyWALL's heap memory is in use. The bar
turns from green to red when the maximum is being approached.
Sessions The first number shows how many sessions are currently open on the ZyWALL.
This includes all sessions that are currently:
• Traversing the ZyWALL
• Terminating at the ZyWALL
• Initiated from the ZyWALL
The second number is the maximum number of sessions that can be open at one
time.
The bar displays what percent of the maximum number of sessions is in use. The
bar turns from green to red when the maximum is being approached.
Network Status
Interface This is the port type. Click "+" to expand or "-" to collapse the LAN drop-down lists.
Status For the LAN ports, this displays the port speed and duplex setting. Ethernet port
connections can be in half-duplex or full-duplex mode. Full-duplex refers to a
device's ability to send and receive simultaneously, while half-duplex indicates
that traffic can flow in only one direction at a time. The Ethernet port must use the
same speed or duplex mode setting as the peer Ethernet port in order to connect.
For the WAN and dial backup ports, it displays the port speed and duplex setting if
you’re using Ethernet encapsulation and Down (line is down or not connected),
Idle (line (ppp) idle), Dial (starting to trigger a call) or Drop (dropping a call) if
you’re using PPPoE encapsulation.
IP Address This shows the port’s IP address.
Subnet Mask This shows the port’s subnet mask.
IP Assignment For the WAN, DHCP client displays if the ZyWALL gets it’s IP address
automatically.
Static displays if the ZyWALL was a manually entered static
(fixed) IP address.
For the LAN, DHCP server displays when the ZyWALL is set to automatically give
IP address information to the computers connected to the LAN. DHCP relay
displays when the ZyWALL is set to forward IP address assignment requests to
another DHCP server. Static displays if the LAN port is using a manually entered
static (fixed) IP address. In this case, you must have another DHCP server on
your LAN, or else the computers must be manually configured.
This shows N/A for the dial backup port.
