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-L42 | Diagnosing and fixing NAT Gateway issues: reading flow logs, resolving misconfigurations, connectivity failures with Azure services, and outbound internet connection problems. |24| Best Practices | L43-L47 | Guidance on reducing SNAT port exhaustion and optimizing outbound connectivity patterns when using Azure NAT Gateway. |25| Decision Making | L48-L53 | Guidance on when to use each Azure NAT Gateway SKU (Standard vs StandardV2), feature/cost tradeoffs, and how to plan and execute migration from Standard to StandardV2. |26| Architecture & Design Patterns | L54-L62 | 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 | L63-L67 | NAT Gateway FAQs plus limits on SNAT ports, IPs, throughput, connections, and other quotas, with guidance on capacity planning and scaling. |28| Configuration | L68-L76 | Configuring NAT Gateway (Standard and StandardV2), managing IPs/resources, setting up flow logs, and configuring monitoring, metrics, and alerts for gateway traffic. |29| Deployment | L77-L83 | 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 |35| Troubleshoot Azure NAT Gateway configuration issues | https://learn.microsoft.com/en-us/azure/nat-gateway/troubleshoot-nat |36| Fix NAT Gateway connectivity with other Azure services | https://learn.microsoft.com/en-us/azure/nat-gateway/troubleshoot-nat-and-azure-services |37| Resolve Azure NAT Gateway outbound connectivity problems | https://learn.microsoft.com/en-us/azure/nat-gateway/troubleshoot-nat-connectivity |3839### Best Practices40| Topic | URL |41|-------|-----|42| Optimize SNAT usage with Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-snat |4344### Decision Making45| Topic | URL |46|-------|-----|47| Migrate Azure NAT Gateway to StandardV2 | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-v2-migrate |48| Choose between Azure NAT Gateway SKUs | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-sku |4950### Architecture & Design Patterns51| Topic | URL |52|-------|-----|53| Design virtual networks using Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-design |54| Scale outbound traffic with NAT Gateway and Azure Firewall | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-hub-spoke-nat-firewall |55| Integrate NAT Gateway in hub-spoke with NVA | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-hub-spoke-route-nat |56| Use NAT Gateway with internal load balancer | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-nat-gateway-load-balancer-internal-portal |57| Use NAT Gateway with public load balancer | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-nat-gateway-load-balancer-public-portal |5859### Limits & Quotas60| Topic | URL |61|-------|-----|62| Azure NAT Gateway FAQ and service limits | https://learn.microsoft.com/en-us/azure/nat-gateway/faq |6364### Configuration65| Topic | URL |66|-------|-----|67| Manage Azure NAT Gateway configuration and IPs | https://learn.microsoft.com/en-us/azure/nat-gateway/manage-nat-gateway |68| Reference for Azure NAT Gateway monitoring data | https://learn.microsoft.com/en-us/azure/nat-gateway/monitor-nat-gateway-reference |69| Enable and use StandardV2 NAT Gateway flow logs | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-flow-logs |70| Configure Azure NAT Gateway resource components | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-gateway-resource |71| Configure metrics and alerts for Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/nat-metrics |7273### Deployment74| Topic | URL |75|-------|-----|76| Deploy Standard V2 NAT Gateway with ARM/Bicep | https://learn.microsoft.com/en-us/azure/nat-gateway/quickstart-create-nat-gateway-v2-templates |77| Redeploy NAT Gateway after cross-region resource move | https://learn.microsoft.com/en-us/azure/nat-gateway/region-move-nat-gateway |78| Move VM public IP outbound traffic to NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-migrate-ilip-nat |79| Migrate outbound access to Azure NAT Gateway | https://learn.microsoft.com/en-us/azure/nat-gateway/tutorial-migrate-outbound-nat |
