1---2name: azure-nat-gateway3description: Expert knowledge for Azure NAT Gateway development including troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, configuration, and deployment. Use when managing SNAT ports, outbound IPs, flow logs, hub-spoke egress, or Azure Firewall integration, and other Azure NAT Gateway related development tasks. Not for Azure Virtual Network (use azure-virtual-network), Azure Virtual Network Manager (use azure-virtual-network-manager), Azure Virtual WAN (use azure-virtual-wan), Azure VPN Gateway (use azure-vpn-gateway).4---5# Azure NAT Gateway Skill67This skill provides expert guidance for Azure NAT Gateway. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, configuration, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213> **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L35-L39 | Diagnosing and fixing NAT Gateway issues: reading flow logs, resolving misconfigurations, connectivity failures with Azure services, and outbound internet connection problems. |24| Best Practices | L40-L44 | Guidance on reducing SNAT port exhaustion and optimizing outbound connectivity patterns when using Azure NAT Gateway. |25| Decision Making | L45-L51 | Guidance on choosing NAT Gateway SKUs, migrating existing NAT Gateways to StandardV2, and moving outbound internet access from other methods to NAT Gateway. |26| Architecture & Design Patterns | L52-L60 | Design patterns for placing NAT Gateway in VNets, hub-spoke, with NVAs, and with internal/public load balancers, plus scaling outbound traffic and combining with Azure Firewall. |27| Limits & Quotas | L61-L65 | NAT Gateway limits, SNAT port quotas, connection scaling behavior, per-resource caps, and FAQs on throughput, IPs, and troubleshooting limit-related issues. |28| Configuration | L66-L74 | Configuring NAT Gateway (Standard and StandardV2), managing IPs/resources, setting up flow logs, and configuring monitoring, metrics, and alerts for gateway traffic. |29| Deployment | L75-L80 | How to deploy and redeploy NAT Gateway (ARM/Bicep), migrate or move outbound traffic from VMs/public IPs, and transition existing outbound access to Azure NAT Gateway. |3031### Troubleshooting32| Topic | URL |33|-------|-----|34| Monitor and troubleshoot with NAT Gateway flow logs | https://learn.microsoft.com/en-us/azure/nat-gateway/monitor-nat-gateway-flow-logs |3536### Best Practices37| Topic | URL |38|-------|-----|39| Optimize SNAT usage with Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-snat |4041### Decision Making42| Topic | URL |43|-------|-----|44| Migrate Azure NAT Gateway to StandardV2 | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-v2-migrate |45| Choose between Azure NAT Gateway SKUs | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-sku |46| Migrate Azure outbound access to NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-migrate-outbound-nat |4748### Architecture & Design Patterns49| Topic | URL |50|-------|-----|51| Design virtual networks using Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-design |52| Scale outbound traffic with NAT Gateway and Azure Firewall | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-hub-spoke-nat-firewall |53| Integrate NAT Gateway in hub-spoke with NVA | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-hub-spoke-route-nat |54| Use NAT Gateway with internal load balancer | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-nat-gateway-load-balancer-internal-portal |55| Use NAT Gateway with public load balancer | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-nat-gateway-load-balancer-public-portal |5657### Limits & Quotas58| Topic | URL |59|-------|-----|60| Azure NAT Gateway FAQs with limits and behavior | https://learn.microsoft.com/en-us/azure/nat-gateway/faq |6162### Configuration63| Topic | URL |64|-------|-----|65| Manage Azure NAT Gateway configuration and IPs | https://learn.microsoft.com/en-us/azure/nat-gateway/manage-nat-gateway |66| Reference for Azure NAT Gateway monitoring data | https://learn.microsoft.com/en-us/azure/nat-gateway/monitor-nat-gateway-reference |67| Enable and use StandardV2 NAT Gateway flow logs | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-flow-logs |68| Configure Azure NAT Gateway resource components | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-resource |69| Configure metrics and alerts for Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-metrics |7071### Deployment72| Topic | URL |73|-------|-----|74| Deploy Standard V2 NAT Gateway with ARM/Bicep | https://learn.microsoft.com/en-us/azure/nat-gateway/quickstart-create-nat-gateway-v2-templates |75| Redeploy NAT Gateway after cross-region resource move | https://learn.microsoft.com/en-us/azure/nat-gateway/region-move-nat-gateway |76| Move VM public IP outbound traffic to NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-migrate-ilip-nat |
