Source NAT—The source addresses in the packets from the clients in the Trust-L3 zone to the server in the Untrust-L3 zone are translated from the private addresses in the network to the IP address of the egress interface on the firewall (

One more VPN article. Even one more between a Palo Alto firewall and a Cisco router. But this time I am using a virtual tunnel interface (VTI) on the Cisco router which makes the whole VPN set a “route-based VPN”. That is: Both devices decide their traffic flow merely based on the routing table and not on access-list entries. Feb 10, 2013 · When creating your NAT Policies and Security Policies on a Palo Alto Networks firewall, you have understand how the Palo Alto runs the packet through its various filters.

Image 4: Deploying a NAT instance to address support for multiple public IPs . Using a NAT Instance. In the case of the NAT instance, we require a worker node, or basic Linux® instance that takes all traffic on its primary instance and

How Does VPN Work? A VPN creates a private connection, known as a “tunnel,” to the internet. All information travelling from a device connected to a VPN will get encrypted and go through this tunnel. When connected to a VPN, a device will behave as if it’s on the same local network as the VPN.
