The solution uses overlay addressing with WireGuard and 1:1 NAT: assign each remote device a unique IP from a separate address space (100.64.0.0/10), place a gateway device at each site to translate between overlay and local addresses, and automate the configuration across hundreds of sites. This eliminates port forwarding, removes security exposure, and makes devices reachable by unique DNS names regardless of local IP conflicts. A production deployment manages 3,000+ cameras across 300 sites using this approach. ## Full article daily.dev links to this article rather than hosting it.
