Magic util that "bridges" Wireguard with OpenVPN without a TUN/TAP interface
Warning: really ugly and unstable code!
Obtain latest source of OpenVPN (link),
apply patch tunsetiff.patch
and place the resulting openvpn
binary in this project's folder.
Then, run go build
(requires Go 1.17 or later).
./wg-ovpn <.ovpn file> <wireguard config file>
Please note that this util doesn't support wg-quick's .conf
format,
rather it uses wireguard-go
's internal UAPI config format:
basically, you can't put section labels like [Interface]
,
everything else works roughly the same (didn't test though)
Example config:
listen_port=55555
private_key=a8dac1d8a70a751f0f699fb14ba1cff7b79cf4fbd8f09f44c6e6a90d0369604f
public_key=28d2b91462b95913ac4fe68259fbabfe4a150314edf04bf4437eaf553d02804c
allowed_ip=0.0.0.0/0
It creates a pair of pseudoterminals that serve as a bidirectional pipe, with one end connected to OpenVPN, and the other one to Wireguard.
It also has a bit of code to replace source/destination IP address to match what OpenVPN expects, so Wireguard clients can use virtually any IP address and still connect to the OpenVPN network.
- only 1 Wireguard client is currently supported
- I have no idea if it works with other OpenVPN setups than what I have
