VPN Best Practices
- 1Use VPC Flow Logs for network traffic monitoring and threat detection
- 2Restrict security group inbound rules to specific CIDR ranges (never 0.0.0.0/0 for SSH/RDP)
- 3Use VPC Endpoints to keep traffic to AWS services off the public internet
- 4Enable WAF with managed rules (AWS Managed Core Rule Set) on all public-facing load balancers
- 5Use Transit Gateway instead of VPC peering mesh for >5 VPCs
Getting Started with VPN in 5 Minutes
- 1Open the AWS Console and navigate to VPN
- 2Click "Create" and define your network scope (VPC, subnets, region)
- 3Configure routing, security, and access controls
- 4Review and create — test connectivity before routing production traffic

Pros
- IPSec VPN tunnels (two per connection for HA)
- AWS Client VPN — OpenVPN-based remote access
- Split tunneling for optimized routing
- NAT Traversal support
- Transit Gateway integration
Cons
- ✕Data transfer costs are notoriously difficult to predict — egress is the #1 hidden cost
- ✕Network ACL and Security Group rules can conflict in complex multi-tier apps
- ✕VPC design mistakes (overlapping CIDRs) are painful to fix after resources are deployed
VPN vs Alternatives
VPN vs VPC
Choose VPN for Hybrid cloud connectivity and Remote workforce access to VPC. It excels at ipsec vpn tunnels (two per connection for ha).
Choose VPC as an alternative when your requirements differ. Each service in the Network category serves different architectural patterns.
