We currently have a primary direct internet from the ISP to the Palo Alto PA-200 configured with LSVPN .
As we plan to have a secondary Internet, we want to connect the Palo Alto PA-200 with 4G Router using LSVPN as well.
The problem is the public IP address is assigned to the 4G router and we'll connect it via LAN With PA-200 as the diagram illustrates below
How can Configure the PA-200 to implement the LSVPN as a client
Does the 4G router have the ability to just pass all traffic without performing any other tasks or to be a transparent device so the PAN could have the public IP? Meaning the PA-200 should be able to make the request to the core of the LSVPN and make the connection. Is this not working as designed?
Why is it a problem if the public IP is on the 4G router? Btw. are you sure your 4G modem has a public IP? The way I used these modems so far, they always got a private IP ln the external interface and on provider side ther is carrier grade NAT for connections towards the internet.
Anyway, for GP LSVPN you don't need a public IP on your spoke firewall. Only the hub will need a public IP to receive the connections.
Which configuration should I do to make the router works transparent in order to carry the public IP address to the firewall? If I configure the DMZ IP on the router by assigning the IP address of the interface of the firewall PA200 will make it transparent?
Which configuration should I put on the firewall (spoke)
Back in the day when i was doing this, there was a setting in the 4g router that allowed it to be transparent and it would pass the public IP to the attached device/firewall. While I dont know what or if there is that in the device you are using, you might want to reach out to the vendor and check. However like @vsys_remo pointed out. it might not be required.
