tcp-over-quic

tcp-over-quic is an WIP implementation for draft RFC Tunneling TCP inside QUIC.

client accepts TCP connection from tcp clients and tunnels data through quic stream. concentrator accepts those quic streams and sends data towards remote TCP server.

Note: tcp-over-quic is not tested in production and probably not ready for production use. at this stage its just a project to learn quic and rust.

simple setup

• run cargo build to build project and generate binaries.

• start concentrator using target/debug/concentrator --quic_serv_port=4433. it will also generate self signed certificate required for quic tls. same certificate will be used by client as well.

• start client, client will listen on tcp port 6970 and it will connect to remote quic server 127.0.0.1:4433. client will send addr 127.0.0.1:7970 as remote tcp address via QUIC tunnel stream TLVs for ALL its TCP connections.

target/debug/client \
    --tcp_source_port=6970 \
    --quic_serv_addr=127.0.0.1:4433 \
    --tcp_dest_addr=127.0.0.1:7970 \
    --quic_serv_cert_path=cert/public_cert.der \
    --quic_serv_name=localhost

• start tcp server on port 7971. using nc -l 127.0.0.1 7970

• send data via tcp client on port 6970 using echo "From tcp client" | nc 127.0.0.1 6970
