The NAT DIPP scalability enhancement for the PA-7500 Series increases the maximum number of supported translated IP addresses from 16,000 to 32,000, enabling large-scale service provider deployments that require extensive source NAT capabilities. This enhancement addresses the critical networking requirements of major telecommunications providers who need to support hundreds of millions of subscribers across multiple regions while maintaining robust internet connectivity and internal infrastructure interconnectivity.

You would benefit from this feature if you operate a large service provider network where traditional NAT translation limits constrain your ability to scale operations effectively. The enhanced capacity is particularly valuable when you need to accommodate substantial customer bases spanning multiple countries or regions. The feature maintains all existing NAT functionality while doubling the translation capacity, ensuring that your network can grow without requiring architectural changes or additional hardware investments.

When deploying the PA-7500 series in your service provider environment, you can now configure up to 32,000 translated IP addresses across standalone deployments, high availability configurations, and clustered environments using C3 Clustering with MLAG. This scalability improvement ensures that PA-7500 Series firewalls can support current operational requirements while providing headroom for future growth, making it possible to standardize on a single firewall platform across your entire network infrastructure without capacity limitations forcing you to seek alternative solutions.
