My paloalto firewall isn't picking up any traffic or showing any sessions.

foresightis — Thu, 27 May 2021 14:27:38 GMT

So i recently configured the Ethernet ports on the firewall and i plugged an Ethernet cable from my switch to port 1 on my firewall and I'm not seeing any traffic logs on the monitor board (only system logs and configuration logs are showing) and it's showing no active sessions. I also plugged the mgmt port to the switch.

*Note: my internet goes into the switch's port 1, I've tried plugging it to one of the ports on the firewall but still the same thing.

please help me out.

The firewall's MGT port is Out-of-Band - it is used for you connecting to web-management only and for the firewall to update itself. This port does not pass network traffic.

Data ports (eth1/1-eth1/8) - these pass network traffic. For this to work you need in & out ports:

1. Set up 2 Layer-3 Ethernet ports, one for LAN and another for WAN (for example). The firewall needs to pass traffic between 2 data ports.

2. Assign each data port a zone, for example 'trust' zone for LAN and 'untrust' zone for WAN (this will be used in policy)

3. Assign IPv4 for the data ports. For example 192.168.10.254/24 on eth1/2 and the default GW for LAN computers is 192.168.10.254 which the firewall will receive. For the WAN port - this is usually details about your ISP connectivity to the internet.

4. Policy (Security & NAT) to allow traffic LAN to WAN and to perform NAT if necessary. Make sure 'log at session end' is selected in the actions tab.

5. Create an account on https://beacon.paloaltonetworks.com, search for edu-110 and register for 'Firewall 9.1 Essentials: Configuration and Management' - this should be 13 hours long and will teach you firewall basics.

Hope this helps,
