Why choose Xelon Cloud?

Overview

Xelon NAT Gateway provides secure, managed network address translation for cloud servers in private subnets. Servers without public IPs can access the internet for software updates, API calls, and external integrations while remaining protected from inbound traffic.

Key Highlights:

  • Outbound-only internet access for private subnet VMs (no inbound connections allowed)

  • Static public IPv4 addresses for consistent source IP (IP whitelisting compatibility)

  • High availability with redundant NAT gateway pairs (99.99% uptime SLA)

  • Automatic scaling to handle traffic bursts (up to 10 Gbps per NAT gateway)

  • Support for multiple availability zones with multi-NAT configurations

  • IPv6 NAT64 support for IPv6-only workloads

Use Cases:

  • Database Servers: Allow databases in private subnets to download updates without public IPs

  • Backend Services: Microservices calling external APIs (payment gateways, SaaS integrations)

  • Compliance: Meet PCI-DSS/HIPAA requirements for private subnet isolation

  • IP Whitelisting: Use static NAT gateway IP for third-party API whitelisting
