How to Connect the Barracuda CloudGen Firewall to Teridion via GRE Tunnel

Teridion Connect provides numerous PoPs (Points of Presence) across the globe, including China, to allow access to their network backbone. The Barracuda CloudGen Firewall can connect to the TCR (Teridion Cloud Router) deployed in one of the PoPs by using IPSec or GRE tunneling to leverage their backbone to improve the connectivity. In addition, BGP can be used as a dynamic routing protocol to learn and propagate networks. For more information, visit the Teridion website.
