# WireGuard Ops
A group of Interactive bash scripts for [WireGuard](https://github.com/WireGuard/wireguard-go) over [udp2raw-tunnel](https://github.com/wangyu-/udp2raw-tunnel), with optional [UDPSpeeder](https://github.com/wangyu-/UDPspeeder) support.
[wg-quick](https://man7.org/linux/man-pages/man8/wg-quick.8.html) compatiable config generator with additional features supported.
## Basic Usage
1. Run `install.sh`. (May prompt sudo)
1. Clone this repo with `git clone https://github.com/Kiritow/wg-ops`
2. Write a valid WireGuard config file, with supported extension tags.
2. Run `install.sh`. (May prompt sudo)
3. Run `python3 generate.py` to convert extension tags into config lines.
3. Write a valid WireGuard `wg-quick` config file, with supported extension tags. (see below)
4. Run `python3 generate.py` to convert extension tags into config lines.
5. Bring it up with `wg-quick up`
Start as service: `systemctl start wg-quick@wg0`

See [wg-quick(8)](https://man7.org/linux/man-pages/man8/wg-quick.8.html) for more information.
Run `python3 generate.py -h` for more help about the generator.
## Options
python3 **generate.py** [-h] [-k] [-o *filename*] *source_filename*
**-h** Display this help and quit.
**-k** Output generated config to standard output
**-o** *filename* Output generated config to `filename`. Default write to *source_filename*.gen
## Generic Tags
**enable-bbr**
Enable [TCP BBR](https://en.wikipedia.org/wiki/TCP_congestion_control#TCP_BBR). Most of the time it's useful on VPS.
**enable-forward**
Set `net.ipv4.ip_forward` to 1. Enable ip packet forward.
**iptables-forward**
Add iptables rules to accept forward from this wireguard interface. Example: `iptables -A FORWARD -i wg0 -J ACCEPT`
**podman-user** *username*
Run podman container as `username`. Default to `root`.
## Tunnel Tags
**udp2raw-server** *name* *port* *password*
Setup a [udp2raw](https://github.com/wangyu-/udp2raw-tunnel) server. Raw mode set to `fake-tcp`. Expose & listen on port `port`.
**udp2raw-client** *name* *port* *remote* *password*
Setup a udp2raw client. Listen on port `port`.
**udp2raw-client-mux** *name* *mux_size* *port* *remote* *password*
Setup multiple (up to `mux_size`) udp2raw clients. Listen on ports from `port` to `port + mux_size`
**gost-server** *name* *port*
Setup a [gost](https://github.com/ginuerzh/gost) server. Forward mode set to `relay+tls`. Expose & listen on port `port`.
**gost-client** *name* *port* *remote*
Setup a gost client. Listen on port `port`.
**gost-client-mux** *name* *mux_size* *port* *remote*
Setup multiple (up to `mux_size`) gost clients. Listen on ports from `port` to `port + mux_size`
**trojan-server** *name* *port* *password* *cert_path* *key_path*
Setup a [trojan-go](https://github.com/p4gefau1t/trojan-go) server. Expose & listen on port `port`.
Requires a ssl certificate signed by trusted CA.
[acme.sh](https://github.com/acmesh-official/acme.sh) is recommended for acquiring ssl certs. Make sure use `fullchain.cer` as `cert_path`
**trojan-client** *name* *port* *password* *remote_host* *target_port*
Setup a trojan-go client. Listen on port `port`.
**trojan-client-mux** *name* *mux_size* *port* *password* *remote_host* *target_port*
Setup multiple (up to `mux_size`) trojan-go clients. Listen on ports from `port` to `port + mux_size`
## Peer Tags
**use-tunnel** *name*
Use tunnel `name` for this peer. wg-ops may add `Endpoint=` or use `wg set peer` to fullfill this requirement.
## Route Tags
**route-to** *ip_route_table*
Used in chained WireGuard settings. Accept any traffic from `ip_route_table`.
Interface marked with `route-to` should have only **one** peer.
**route-from** *ip_route_table*
Used in chained WireGuard settings. Route traffic from all peers or a marked peer with `ip_route_table`.
Example: The following config means all traffic from `10.44.0.2` will be forward to `10.33.0.1`
wg0.conf (Should have only one peer)
```

## Notice
Make sure to setup firewall. UFW is recommended.
For a forwarding server, the following commands might be needed:
```
ufw route allow in on wg0 out on wg0
```
Reload script only reload wireguard configs. Changes made to tunnels will not work without restart.
Make sure to setup firewall for better security. [ufw](http://manpages.ubuntu.com/manpages/bionic/man8/ufw.8.html) is recommended for Ubuntu.
