NetProxyCLI 1.0.0

NetProxy

Netproxy is a simple ipv4 UDP & TCP proxy based on .NET 5.0. The upstream repository uses a configuration file, and my use case was more temporary, therefore a CLI seemed more appropriate.

Installing

dotnet tool install --global NetProxyCLI

Why?

When dealing with corporate firewalls and segregated networks, sometimes you need a quick and dirty reverse proxy in order to test software, or facilitate development. Setting up a full instance of nginx isn't necessarily difficult, but way overkill for this situation.

I found the upstream repository, refactored it to my liking, removed IPv6 support (I'm open to bringing it back, its just not in my use case), and published it under a new name

Usage

This version of NetProxy uses a CLI that supports the following formats. That parser is quite naive, so please report any issues

Proxy Definition Formats:
  [IP]:[Port]~[IP]:[Port]/[Protocol]
  [IP]:[Port]~[IP]/[Protocol]
  [IP]~[IP]:[Port]/[Protocol]

  [Port]~[IP]/[Protocol]
  [IP]:[Port]~[IP]:[Port]
