This could potentially give you the best of both worlds.

Layer 2 palo alto networks. Used when switching between two or more networks. It has separate data plane and control plane. The Layer 2 hosts are probably geographically close to each other and belong to a single broadcast domain.

Used in conjunction with SPANRSPAN to monitor traffic. This document covers the configuration on the Layer 2. Traffic traversing the firewall is examined as per policies providing increased security and visibility within the internal network.

3162015 How to run Palo Alto Networks in AWS or Google cloud in Layer 2 mode for demos PoCs and testing. 5142020 Deploy VM-Series on ESXi in Layer 2. This configuration note walks through the details of configuring a site-to-site IPSec tunnel with the firewall deployed in layer 2 modes.

Layer 2 Configuration For each Layer 2 interface you require a security zone. Palo Alto Networks PAN has a fast growing ecosystem of resellers technology partners and customers. Palo Alto Next Generation Firewall deployed in Layer 2 mode In Layer 2 deployment mode the firewall is configured to perform switching between two or more network segments.

Two VLAN-Interfaces Layer3 provide routing and are configured with Layer3 Zones. Layer 2 interfaces - Palo Alto Networks Training. Be sure to configure the appropriate default gateway on the Virtual Router.

But Im not running layer 2 in production to compare. For example you can create VLANs for the Finance and Engineering departments. You could deploy using vsys and have some layer three segments and treat others are v-wire and layer 2.

End clients are located behind these interfaces but they cannot communicate with each other. The two physical interfaces Layer2 have two subinterfaces with the VLANs 120 and 125 configured. PAN-OS is very flexible allowing administrators to mix and match physical firewall interfaces amongst virtual wire layer 2 layer 3 and tap mode configurations.

Public clouds like AWS or Google are ideal for these. The following screenshots show the configuration on the Palo Alto firewall. In a Layer 2 deployment the firewall provides switching between two or more networks.

Layer 2 Configuration PA-200. Select New Zone from the Security Zone drop-down define a Name for new zone for example client and then click OK. User-ID becomes a WHO statement.

512019 Heres how you can apply the Kipling Method when deploying the Palo Alto Networks Next-Generation Firewall using our revolutionary User-ID App-ID and Content-ID technologies.

2010 Palo Alto Networks Page 3 Overview Palo Alto networks firewalls can deployed in the networks as Layer 2device o ffering all the security features. This issue is encountered when the layer 2 interfaces have not been assigned to layer 2. This document explains PAN-OS layer 2 and VLAN concepts showing examples of connecting a VLAN with Layer 2 interfaces to a Layer 3 interface for connectivity off of the VLAN network.

The firewall forwards the frames to the proper port which is associated with the MAC address identified in the frame. Layer 2 and Layer 3 Packets over a Virtual Wire A virtual wire interface will allow Layer 2 and Layer 3 packets from connected devices to pass transparently as long as the policies applied to the zone or interface allow the traffic. I dont see any performance impact on the v-wire deploys we manage.

First Palo Alto Firewall Architecture design split up the 2 planes ie. Dedicated processor responsible for network tasks such as routing NAT QOS route lookup MAC Lookup and network layer communications. Palo Alto Networks firewalls can be deployed in the networks as Layer 2 device offering all the security features.

Also create a Layer 2 zone and append this interface to it. Learn about topology system requirements and VM-Series Layer 2 Configuration. Configure a Layer 2 Interface when switching is required.

Ill just add another option to complicate things for you. Layer 2 Interfaces with No VLANs. Devices are connected to a Layer 2 segment.

Configure a Layer 2 interface and connect it to your Layer 2 network. Repeat steps 2 and 3 above for the other interface. When your organization wants to divide a LAN into separate virtual LANs VLANs to keep traffic and policies for different departments separate you can logically group Layer 2 hosts into VLANs and thus divide a Layer 2 network segment into broadcast domains.

Palo Alto Networks covers the deployment of the VM-Series Next-Generation Firewall on the ESXi hypervisor in Layer2 mode. This ecosystem needs complete fully featured PAN environments for - demos PoCs and testing. The Palo Alto Networks Firewall is configured with multiple L2 interfaces belonging to the same VLAN.

Select the Config tab and complete the following tasks. This document covers the configuration on the Layer 2 firewall. This configuration note walks through the details of configuring a site-to-site IPSec tunnel with the firewall deployed in layer 2 modes.
