- Default subnets in consumer routers and ISP modems cause address conflicts across multiple customer sites.
- Traditional solutions like port forwarding and subnet routing fail due to dynamic NAT configurations and overlapping subnets.
- Overlay addressing with 1:1 NAT assigns unique IPs in the 100.64.0.0/10 range, avoiding conflicts and enabling secure access.
- A gateway device on each customer's LAN performs NAT translation, allowing devices to be accessed via unique overlay addresses.
- Netrinos automates the configuration of WireGuard peers, NAT rules, and DNS records across hundreds of sites.
- This approach eliminates the need for port forwarding, reduces attack surfaces, and ensures connectivity despite ISP changes.
