Netproxy is a simple ipv6/ipv4 UDP & TCP proxy based on .NET Core. It should build and run for any .NET Core 1.1 compatible platform, tested on win10-x64 and ubuntu.16.10-x64.
We needed a simple, crossplatform IPV6 compatible UDP forwarder, and couldn't find a satisfying solution. Nginx was obviously a great candidate but building it on Windows with UDP forwarding enabled was quite a pain.
The objective is to be able to expose as an ipv6 endpoint a server located in an ipv4 only server provider. (Yes, as of 07/2017, I'm looking at you Google! Ok, you support ipv4 for TCP, but what about UDP?)
Error management exist, but is minimalist. IPV6 is not supported on the forwarding side.
- Compile for your platform following instructions at https://www.microsoft.com/net/core
- Rewrite the config.json file to fit your need
- Run NetProxy
Config.json contains a map of named forwarding rules, for instance :
{
"http": {
"localport": 80,
"localip":"",
"protocol": "tcp",
"forwardIp": "xx.xx.xx.xx",
"forwardPort": 80
},
...
}
- localport : The local port the forwarder should listen to.
- localip : An optional local binding IP the forwarder should listen to. If empty or missing, it will listen to ANY_ADDRESS.
- protocol : The protocol to forward.
tcporudp. - forwardIp : The ip the traffic will be forwarded to.
- forwardPort : The port the traffic will be forwarded to.
