tun2proxy
Tunnel TCP traffic through SOCKS5 or HTTP on Linux.
Authentication not yet supported. Error handling incomplete and too restrictive.
Build
Clone the repository and cd into the project folder. Then run the following:
cargo build --release
Setup
A standard setup, which would route all traffic from your system through the tunnel interface, could look as follows:
# Create a tunnel interface named tun0 which your user can bind to.
sudo ip tuntap add name tun0 mode tun user $USER
sudo ip link set tun0 up
# To prevent a loop, replace 1.2.3.4 with the IP address of the proxy server.
# This will add a route to the proxy server that behaves like the default route.
sudo ip route add 1.2.3.4 $(ip route | grep '^default' | cut -d' ' -f2-)
# Route all your traffic through tun0 without interfering with the default route.
sudo ip route add 128.0.0.0/1 dev tun0
sudo ip route add 0.0.0.0/1 dev tun0
# Again, replace 1.2.3.4 with the IP address of the proxy server.
./target/release/tun2proxy --tun tun0 --socks5 1.2.3.4
Note that if you paste these commands into a shell script, which you then run with sudo, you might want to replace
$USER with $SUDO_USER.
