Routes AWS networking requests to the correct service skill for implementation. Covers Route 53 (DNS, health checks, routing policies, Resolver, DNS Firewall), CloudFront (caching, edge, OAC, mTLS, signed URLs), Transit Gateway (multi-VPC hub, segmentation, centralized egress), Direct Connect (hybrid link, DX Gateway, MACsec), Site-to-Site VPN (IPsec tunnels, static or BGP), WAF (web ACLs, AWS Managed Rules, rate-based rules, Bot and Fraud Control), and Shield Advanced (L3/L4 DDoS). Applicable when creating, configuring, troubleshooting, or designing across these services, choosing between them, or diagnosing connectivity or traffic-filtering issues. Not for VPC subnets and route tables, load balancers, VPC endpoints, PrivateLink, API Gateway, IAM policy logic, container or serverless networking, or IaC authoring.

AI-generated overview

Routes AWS networking requests to the right service skill for Route 53, CloudFront, Transit Gateway, Direct Connect, VPN, WAF or Shield.

What it does: This is a triage router for AWS networking work. It matches a request against a routing table of seven service skills (Route 53, CloudFront, Transit Gateway, Direct Connect, Site-to-Site VPN, WAF, Shield Advanced) and points to the target skill document. It also provides cross-service tables for filtering, logging, and traffic shifting, plus security considerations to raise during handoff. It does not implement configurations itself.
When to use it: Use it when a request involves DNS, content delivery, hybrid connectivity, or network security across those AWS services, including choosing between them or diagnosing connectivity and traffic-filtering problems. It is not intended for VPC subnets and route tables, load balancers, VPC endpoints, PrivateLink, API Gateway, IAM policy logic, container or serverless networking, or IaC authoring.
Requirements: Instructions only, no scripts. Works with standard AWS CLI access; the AWS MCP server is recommended for sandboxed execution, audit logging, and enterprise controls. Retrieving a target skill uses the MCP retrieve-skill call or the repository path skills/ /SKILL.md.

AWS Networking

Overview

Routes networking requests to the correct service-specific skill. Covers 7 services across DNS and content delivery, hybrid connectivity, and network security (web application firewall and DDoS protection). Other AWS networking services (VPC foundations, load balancing, endpoints, PrivateLink, API Gateway, and more) are out of scope for this router (see step 6).

Works best with the AWS MCP server — enables sandboxed execution, audit logging, and enterprise controls. All guidance also works with standard AWS CLI access.

How to use this skill

Match the user's request against the Skill Routing Table below. Match on meaning, not exact wording.
If the request matches multiple skills, use the Cross-Service Concepts tables to determine which layer the request targets, then route to the skill that owns that layer.
If still ambiguous, ask one clarifying question: "Are you looking to set up connectivity, or control/filter existing traffic?"
Load the target skill: if the AWS MCP server is available, use aws___retrieve_skill(skill_name="<skill>"); otherwise retrieve the skill document from this repository at skills/<skill>/SKILL.md.
If a request spans multiple of these skills, route to each in dependency order. When routing to an internet-facing service (cloudfront), also route to shieldadvanced for DDoS protection and to waf for L7 filtering (AWS WAF attaches to CloudFront, Application Load Balancer, API Gateway, and AppSync), if the user has not already addressed L7 filtering and DDoS protection. When routing to a connectivity skill (directconnect, sitetositevpn, transitgateway), confirm encryption in transit is addressed (MACsec for Direct Connect, IPsec for VPN, inter-region peering encryption for Transit Gateway). When the request involves custom domains or TLS on cloudfront, note that ACM certificate provisioning is part of the implementation. When routing to cloudfront for a web-facing distribution, note that the target skill should address security response headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) via a CloudFront Response Headers Policy, including the managed SecurityHeadersPolicy. The target skill handles the configuration.
If the request is an AWS networking task that is not in the Skill Routing Table (for example VPC subnets or route tables, security groups, load balancers, VPC endpoints, PrivateLink, or API Gateway), tell the user that service is not available in this skill set rather than routing to the closest listed skill. This skill set does not cover every AWS networking service.
This skill triages — it does not implement. Do not answer service-specific configuration questions from this skill alone.

Connectivity vs Security

Dimension	Connectivity	Security
Answers	Can traffic reach its destination?	Should traffic be allowed?
Failure symptom	Timeout, unreachable, black hole	Rejected, denied, dropped
Dependency	Independent of policy — path exists or it doesn't	Assumes connectivity exists — can only filter reachable traffic
Granularity	Affects all flows on a path	Targets specific flows by match criteria

Skill Routing Table

Skill	Choose when…
`transitgateway`	Connecting more than two VPCs or on-premises networks in a hub, routing segmentation, cross-account/cross-region connectivity at scale, centralized egress/inspection, multicast
`directconnect`	Dedicated private link to on-premises — consistent latency, high throughput, MACsec encryption, LAGs, Direct Connect Gateway for multi-VPC, SiteLink for site-to-site bypass, production hybrid workloads
`sitetositevpn`	Encrypted IPsec tunnel over internet — quick setup, DX backup, static or BGP routing, accelerated option via Global Accelerator backbone, standard or large tunnel bandwidth
`route53`	DNS management (public/private zones, records), health checks, routing policies (weighted, failover, geo, latency), domain registration, Resolver (hybrid DNS forwarding), DNS Firewall, Route 53 Profiles, Global Resolver
`cloudfront`	Caching, TLS termination at edge, origin protection (OAC), custom domains, cache policies/behaviors, signed URLs, CloudFront Functions, viewer mTLS, VPC origins, multi-tenant distributions
`waf`	Web application firewall (L7) — web ACLs on CloudFront/ALB/API Gateway/AppSync, AWS Managed Rules, rate-based rules for HTTP floods, IP/geo match, Bot Control, Fraud Control (account takeover/creation), for protecting web apps and APIs from exploits, bots, and credential stuffing
`shieldadvanced`	L3/L4 DDoS protection for internet-facing resources, automatic application-layer (L7) mitigation via WAF, health-based detection, Shield Response Team access, and DDoS cost-protection credits

Cross-Service Concepts

Same concept, different service depending on layer. Use these to disambiguate when the Skill Routing Table matches multiple skills.

Filtering / Blocking

Use when the user says "block", "deny", "filter", or "restrict traffic" — determines which layer the filtering operates at.

Layer	Service	What it filters on	Skill
L7 (HTTP/HTTPS, web apps and APIs)	AWS WAF	HTTP request attributes, AWS Managed Rules, rate-based and bot rules, IP/geo match	`waf`
L3/L4 (DDoS volumetric/state-exhaustion)	Shield Advanced	Network/transport-layer DDoS floods on internet-facing resources	`shieldadvanced`
DNS (resolution)	Route 53 DNS Firewall	Domain name patterns — blocks resolution, not traffic	`route53`

When routing to waf or cloudfront for an internet-facing API or website, treat WAF rate-based rules as a default protective measure, not only when the user asks: note that the target skill should add WAF rate-based rules to bound request volume per client — the target skill implements it.

Logging / Visibility

Use when the user says "logs", "visibility", "what's being blocked", or "can I see the traffic" — identifies which log source to check.

What you need to see	Service	Log type	Skill
DNS queries from VPC	Route 53 Resolver	Query logs	`route53`
Blocked/allowed HTTP requests	AWS WAF	web ACL logs (S3, CloudWatch Logs, or Kinesis Data Firehose)	`waf`
DDoS events and attack detail	Shield Advanced	CloudWatch metrics, DDoS event detection	`shieldadvanced`
Edge/CDN request access	CloudFront	Standard logs (S3), real-time logs (Kinesis Data Streams)	`cloudfront`
Tunnel state and traffic	Site-to-Site VPN	Tunnel telemetry, CloudWatch metrics	`sitetositevpn`

When routing to any of these services, remind the user to enable the corresponding logging (above) for security visibility and incident response — the target skill implements it. These logs can contain sensitive data (request query strings, internal hostnames in DNS queries), so also remind the user that the log destination (S3, CloudWatch Logs, Kinesis Data Firehose, or Kinesis Data Streams) MUST have encryption at rest enabled and access restricted to authorized personnel — the target skill implements it.

Traffic Shifting

Use when the user says "shift traffic", "blue/green", "failover", "canary", or "weighted routing" — determines the granularity and which service controls it.

Security Considerations

These services are security-sensitive, so raise the relevant risk and control when routing regardless of which skill you hand off to — the target skill implements the control:

Risk	Control the target skill should address	Skills
Unencrypted traffic in transit	MACsec (`directconnect`), IPsec tunnels (`sitetositevpn`), inter-region peering encryption (`transitgateway`), TLS termination and viewer mTLS (`cloudfront`)	`directconnect`, `sitetositevpn`, `transitgateway`, `cloudfront`
Missing DDoS protection on internet-facing resources	Shield Advanced L3/L4 protection plus WAF L7 mitigation	`shieldadvanced`, `waf`
Web/API exploits, bots, and request floods	WAF web ACLs, AWS Managed Rules, and rate-based rules; application-layer input validation (request body size limits, schema validation); security response headers	`waf`, `cloudfront`
Overly permissive filtering rules	Least-privilege DNS Firewall domain blocking	`route53`
Over-privileged IAM policies for service resources	Least-privilege IAM roles scoped to specific resources and actions; avoid `FullAccess` managed policies and `Action: *`; prefer IAM roles with ephemeral credentials (instance profiles, IRSA, task roles, `sts assume-role`) over IAM users with long-lived access keys	all
Hardcoded credentials and shared secrets	Let AWS auto-generate secrets where supported (for example Site-to-Site VPN pre-shared keys), or store customer-managed secrets in AWS Secrets Manager rather than hardcoding them	`sitetositevpn`, `directconnect`
Confused-deputy in cross-service resource policies	Include `aws:SourceArn` and/or `aws:SourceAccount` condition keys in S3 bucket policies, KMS key policies, and log-destination resource policies (CloudFront OAC, log delivery to S3/CloudWatch Logs/Kinesis) so only the intended resource and account can invoke them	`cloudfront`, `waf`, all
Insufficient visibility for incident response	Enable the service logging in the Logging / Visibility table, with encryption at rest and restricted access on the log destination	all
No audit trail or alerting on control-plane changes	Enable AWS CloudTrail to audit control-plane API calls (record, rule, policy, and firewall changes) and set CloudWatch Alarms on security-relevant events (Shield Advanced DDoS detection, WAF blocked/counted spikes, unexpected rule or record modifications); restrict the SNS topics that receive alarm notifications to authorized personnel and enable encryption at rest (SSE-KMS) on those topics, since the notifications can contain sensitive event detail	all
