# t2q2t
t2q2t is a port forward tool that converts between TCP and QUIC. (TCP/QUIC Proxy).
You can benefit from QUIC with any application protocol using t2q2t.
usecase overview are below:
- Client: listens on `0.0.0.0:2022` with TCP, and forwards to `192.168.0.1:22`(server ip) with QUIC
- Server: listen on `0.0.0.0:2022` with QUIC, and forward to `127.0.0.1:22` with TCP
```
# t2q2t
# on client side (TCP <-> QUIC)
$ ./t2q2t t2q 0.0.0.0:2022 192.168.0.1:2022
# on server side (QUIC <-> TCO)
$ ./t2q2t q2t 0.0.0.0:2022 127.0.0.1:22
```
You can use SSH with QUIC transport by running t2q2t on client and server.
## build
```
$ git clone https://github.com/flano-yuki/t2q2t.git
$ cd ./t2q2t
$ CGO_ENABLED=0 GOOS=linux GOARCH=amd64 GO111MODULE=on go build t2q2t.go
$ go build ./t2q2t.go
```
You can also use the following Dockerfile to try it out in your Docker environmemnt.
```
# In the project root directory
$ docker build -t flano-yuki/t2q2t .
$ docker run -it -p 2022:2022 -p 2022:2022/udp --rm flano-yuki/t2q2t

```
## convert mode (sub command)
- `t2q`: Listen by TCP, and connect to QUIC
- `q2t`: Listen by QUIC, and connect to TCP
## Note
This is a PoC.
t2q2t uses "t2q2t" as the ALPN identifier. It is not intended to communicate with other QUIC implementations.
TODO
- Improve error handling
- Improve connection management
- (Output connection statistics)
- Many other improvements
