AWS VPC Terraform module
Terraform module which creates VPC resources on AWS
...By default, if NAT Gateways are enabled, private subnets will be configured with routes for Internet traffic that point at the NAT Gateways configured by use of the above options. Since AWS Lambda functions allocate Elastic Network Interfaces in proportion to the traffic received, it can be useful to allocate a large private subnet for such allocations, while keeping the traffic they generate entirely internal to the VPC. -

Tailscale
The easiest, most secure way to use WireGuard and 2FA
Tailscale is an open-source zero-configuration VPN and networking solution that makes it simple to create secure, private networks across devices by leveraging WireGuard under the hood. It lets users connect computers, servers, mobile devices, and cloud instances together with peer-to-peer encrypted tunnels without dealing with complex firewalls, NAT rules, or key distribution headaches. Instead of traditional VPN server infrastructure, Tailscale uses a coordination service to authenticate devices and exchange connection information, enabling automatic NAT traversal and minimal manual setup. The project includes a daemon (tailscaled) and a CLI tool that run on major operating systems, and it also forms the basis for the official clients on platforms like iOS and Android, though those have GUI wrappers not fully in this repository. -

NSmartProxy
NSmartProxy is an open source reverse proxy tool
NSmartProxy is a reverse proxy system that enables external access to devices or applications behind NAT/firewalls without requiring public IPs or router configuration. It’s designed to work with desktop and server apps, and includes a centralized SmartNode server that helps initiate and maintain tunnel connections. This makes it ideal for remote access to local services or self-hosted applications. NSmartProxy supports both TCP and UDP protocols, making it versatile for a wide range of network needs. -

cunicu
A zeroconf peer-to-peer mesh VPN using Wireguard
...Hence, it adopts the design goals of the WireGuard project, to be simple and easy to use. Thanks to Interactive Connectivity Establishment (ICE), cunīcu is capable of establishing direct connections between peers that are located behind NAT firewalls such as home routers. In situations where ICE fails, or direct UDP connectivity is not available, cunīcu falls back to using TURN relays to reroute traffic over an intermediate hop or encapsulate the WireGuard traffic via TURN-TCP. -

frp
A Fast Reverse Proxy
frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others. -

nginx-proxy
Automated nginx proxy for Docker containers using docker-gen
nginx-proxy sets up a container running nginx and docker-gen. docker-gen generates reverse proxy configs for nginx and reloads nginx when containers are started and stopped. The containers being proxied must expose the port to be proxied, either by using the EXPOSE directive in their Dockerfile or by using the --expose flag to docker run or docker create and be in the same network. By default, if you don't pass the --net flag when your nginx-proxy container is created, it will only be... -

rathole
A lightweight and high-performance reverse proxy for NAT traversal
A secure, stable and high-performance reverse proxy for NAT traversal, written in Rust. rathole, like frp and ngrok, can help to expose the service on the device behind the NAT to the Internet, via a server with a public IP. High Performance Much higher throughput can be achieved than frp, and more stable when handling a large volume of connections. Low Resource Consumption Consumes much fewer memory than similar tools. -

UFTP
Encrypted UDP based FTP with multicast
...The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers. -

Udp2raw-tunnel
Turns UDP traffic into encrypted UDP/fakeTCP/ICMP traffic
...Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization). -
