Relay TCP/UDP to SOCKS5.
--------------------------------- ---------------- ------------------
| Nintendo Switch/Other devices | ----> | gatewaysocks | ----> | socks5 proxy |
| 10.6.0.2/255.255.255.0 | ----> | 10.6.0.1 | ----> | 127.0.0.1:1080 |
--------------------------------- ---------------- ------------------
Prepare a socks5 proxy(e.g. stunnel), which should support TCP/UDP proxy.
Run gatewaysocks as root.
./gatewaysocks [-s socks5-address(e.g. 127.0.0.1:1080)] [-i interface(e.g. en0)] [--gateway-ip ip(e.g. 10.6.0.1)] [--subnet-mask mask(e.g. 255.255.255.0)]
By default, socks5 address is 127.0.0.1:1080, gateway address is 10.6.0.1, subnet mask is 255.255.255.0.
Change console(e.g. Nintendo Switch) setting, set IP to 10.6.0.2 or others in the subnet 10.6.0.1/255.255.255.0, set gateway to 10.6.0.1, set subnet mask to 255.255.255.0, change DNS(e.g. 8.8.8.8).

gatewaysocks was tested on macOS(M1 chip) and Linux.
