Hello Team,<br />
<br />
I used to have my vpn tunnels using sonicwall to sonicwall. Some of my remote offices are hiding behind a natted static public ip address and the wan interface of the sonicwall has a private ip address assigned. When using sonicwall to sonicwall a public vpn tunnel can still be accomplished in this scenario when specifying the PEER IKE IP (private ip of the wan interface) on the sonicwall on the other site along with the public ip. This is refereed to as NAT Traversal.<br />
<br />
Now we're moving to Checkpoint in our primary site where all our remote offices connect to, so we need to have a checkpoint to sonicwall VPN and so far it works fine except on the sites that are using NAT Traversal. How can we apply this same PEER IKE IP concept in the checkpoint connecting to the sonicwall with a private ip address in the WAN interface.<br />
<br />
Thank you.

Checkpoint to Sonicwall VPN tunnel using NAT Traversal.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
