# mtcp

mtcp is a Rust TCP/IP stack that presumes a perfect network layer.

# Usage

    cargo build --release

An example that listens on `tun1` interface, forwards traffic through `127.0.0.1:3148` and uses remote DNS for resolving domains is


    sudo ip tuntap add dev tun1 mode tap user $YOUR_USER_ID
    sudo ip a a dev tun1 10.0.0.1/24"
    sudo route add default gw 10.0.0.2 metric 6

    cargo run --release -- '127.0.0.1:3148' --dns 8.8.8.8 --tun tun1
    
    sudo ip route del default via 10.0.0.2
