This address is called the layer 3 address or IP address. A process to analyze the layer 3 header and taking the forwarding decision based on the destination address is called the routing. Routing is performed by routers, firewalls, multi-layer switches and gateways.

Convergence enables Cato to collapse multiple security solutions such as a next-generation firewall, secure web gateway, anti-malware, and IPS into a cloud service that enforces a unified policy across all corporate locations, users and data. The external IP addresses of the PoPs are protected with specific anti-DDoS measures.

Organizations require a WAN that is capable of optimizing traffic flow between any two points not just to/from the enterprise LAN without compromising security. In addition, custom application definitions identify account-specific applications by port, IP address or domain.

Since we are focused on the cloud in this article, we find that SNMP is great for LANs and WANs, but we can’t use it to see inside devices within the cloud. Performing a TCP traceroute to IP addresses and host names is just the beginning. To learn more, read “ How to Monitor Traffic Through Transit Gateways.”.

Step 4# Check NAT (Network Address Translation) NAT Traversal: Ensure NAT traversal (NAT-T) is enabled if the traffic is passing through a NAT device. Some IPsec VPN configurations may require this to avoid issues with IP address translation. To verify, go to Network NAT Check the configuration for any conflicting rules.
