Reyes

Reyes populates IPTables firewall rules based on EC2 security group rules. Named after the Pt. Reyes Lighthouse, which shines light through the fog, preventing your ships from crashing on the rocks as they make their way to port.

Use Case

Reyes is designed to apply security group rules to IPsec VPN traffic that would otherwise be injected past security group protection. This is useful for enforcing firewalls on VPNs between EC2 instances and security groups in other VPCs, even in other regions.
