# safehaven
* Architecture
## How does it work
Checkout my blog [post](https://kwakubiney.github.io/posts/UDP-Tunneling-With-Safehaven/) for implementation details.
## Demo
[Click here to watch demo](https://www.youtube.com/watch?v=BJcXyx5ae1Ac)
## How to use?
* Only available on Linux
```
Usage:
-d string
private network destination (default "10.108.0.2")
-g global
routes all traffic to tunnel server
-l string
local address
-s string
remote server address (default "138.197.32.138")
-srv
server mode
-tc string
client tun device ip (default "192.168.1.100/24")
-tname string
tunname (default "tun0")
-ts string
server tun device ip (default "192.168.1.102/24")
```
* Build the project.
* Run using appropriate flags on client.
* Run on server in `server mode` and also run `sysctl -w net.ipv4.ip_forward=1` on server to allow IP forwarding.
* `ping` destination address from client after setup & you should receive echo replies back.
`NB`: Your server must know how to reach the private network else your packet will get lost in the sauce on the server.
