Packet Capture
Packet capture is a computer networking term for intercepting a data packet that
is crossing or moving over a specific computer network.

drop-down menu select your connection type (LAN, DSL WAN or ETH WAN).
• Click Start to start the packet capture.
• Click Stop to stop the packet capture.
• Click Save packet log to save the packet log.
STEP 4 DSL Diagnostics. Click Enable to enable the DSL Diagnostics.
Port Mirroring
Port mirroring monitors network traffic by sending copies of all incoming and
outgoing packets from one port to a monitoring port. You can use port mirroring as
a diagnostic or debugging tool, when fending off an attack or viewing user traffic
from LAN to WAN to see if users are accessing information or websites they are
not supposed to.
The LAN host (PC) should use a static IP address to avoid any issues with port
mirroring. DHCP leases can expire for a LAN host and can cause port mirroring to
fail if a static IP address is not configured for the LAN host.
To configure port mirroring:
STEP 1 Select Administration > Diagnostics > Port Mirroring.
STEP 2 From the Mirror Destination Port drop-down menu, select a mirror port. If you use
a port for mirroring, do not use it for any other traffic.
STEP 3 In the Mirror Source Port field, select the ports to mirror.
STEP 4 Click Save.
