Create a new inbound firewall rule to allow specific traffic to reach instances within an isolated network.
This endpoint allows you to configure network security by creating rules that permit inbound traffic based on protocol, ports, and source IP addresses. Essential for enabling secure access to services while maintaining network security.
Protocol Support:
- TCP/UDP Rules: Configure port forwarding with public-to-private port mapping
- ICMP Rules: Allow specific ICMP types and codes for network diagnostics
Key Features:
- Port Forwarding: Map public ports to private instance ports for TCP/UDP
- Source IP Control: Restrict access to specific IP addresses or ranges
- Protocol Flexibility: Support for TCP, UDP, and ICMP protocols
- Instance Targeting: Direct traffic to specific network interface IPs
Security Best Practices:
- Use specific source IP ranges instead of 0.0.0.0/0 when possible
- Configure only necessary ports and protocols
- Use non-standard ports for enhanced security
- Regularly review and audit firewall rules
Rule Requirements:
- TCP/UDP: Requires public port, private port, and target NIC IP
- ICMP: Requires ICMP type and code specifications
- All Protocols: Requires source IP address or range
