Migrate FortiGate to Palo Alto NGFW - 2019

L0 Member

Hello All,

I wanted to start this new discussion as I am working thru the process of migrating off of an FortiNet Firewall and onto a Palo Alto Firewall and am working with the Palo Alto Expedition Tool.  I am hoping that this discussion can be referenced in the future for others who are going to be tackling a similar project and provide any help/insight that I can along the way.


Hello Kris,


You would want to remap these interfaces within the expedition tool to make this work. What fortinet considers a WAN interface is the interface facing the provider edge, which we could use as a zone interface but for IPSEC tunneling ideally you would use the tunnel interfaces provided within the PAN ( IPSEC set up is here https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClGkCAK ) The pass through for these IPSEC VPN's would be your provider edge egress point and you could have multiple VPN's traversing this interface. So if you are going to just migrate over a single VPN from the interface WAN1 you would want remap it into a tunnel interface and the outgoing interface would be the publicly routable IP on an egress interface towards your provider but the tunnel interface will encapsulate the VPN packet across that interface.
