From azure
Expert knowledge for Azure NAT Gateway development including troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, configuration, and deployment. Use when planning SNAT capacity, configuring IPs/flow logs, fixing outbound failures, or choosing Standard vs StandardV2, and other Azure NAT Gateway related development tasks. Not for Azure Firewall (use azure-firewall), Azure Load Balancer (use azure-load-balancer), Azure Virtual Network (use azure-virtual-network), Azure Virtual WAN (use azure-virtual-wan).
