Table 19-5 Protocol/ Port Report
LABEL DESCRIPTION
Protocol/Port This column lists the protocols or service ports for which the most traffic has gone
through the ZyWALL. The protocols or service ports are listed in descending order
with the most used protocol or service port listed first.
Direction This field displays Incoming to denote traffic that is coming in from the WAN to the
LAN. This field displays Outgoing to denote traffic that is going out from the LAN to
the WAN.
Amount This column lists how much traffic has been sent and/or received for each protocol or
service port. The measurement unit shown (bytes, Kbytes, Mbytes or Gbytes) varies
with the amount of traffic for the particular protocol or service port. The count starts
over at 0 if a protocol or port passes the bytes count limit (see Table 19-7 Report
Specifications).
19.3.3 Viewing LAN IP Address
In the Reports screen, select LAN IP Address from the Report Type drop-down list box to have the
ZyWALL record and display the LAN IP addresses that the most traffic has been sent to and/or from and
how much traffic has been sent to and/or from those IP addresses.
Computers take turns using dynamically assigned LAN IP addresses. The
ZyWALL continues recording the bytes sent to or from a LAN IP address when it
is assigned to a different computer.
