6.10 How to Capture Packets on the ZyWALL

This example traces the IPv4 packets (you can also capture IPv6 packets) sent from or to a specific

IP address (172.16.1.33) through the ZyWALL’s LAN1 and WAN1. You have to evaluate when the

best timing is to capture packets for troubleshooting and do it at the right time.

1 Go to Maintenance > Diagnostics > Packet Capture > Capture, select wan1 and lan1 and

move them to the Capture Interfaces box.

Select IPv4 in the IP Version field.

Select User Defined and enter 172.16.1.33 in the Host IP field.

Select Save data to onboard storage only (if the displayed available size is enough). Click

Capture.
