1 Cradlepoint to Paloalto VPN Example Summary This configuration covers an IPSec VPN tunnel setup between a Cradlepoint Series 3 router and a Paloalto firewall. IPSec is customizable on both the Cradlepoint and Paloalto platforms to fit into a variety of network and security requirements however; this configuration example will address only the basic configuration and a VTI configuration (Firmware 5.4 or greater). Standard IPSec VPN Topology 1
