An Easy and Simple Anti-DDoS solution for VPS,Dedicated Servers and IoT devices based on iptables/ipsets

![](nshield-scheme.png?raw=true)

-----------------

## Requirements

- Linux System with golang, iptables/ipsets

- Nginx 

### Quickstart

Run the bash script (install.sh) to install all the required dependencies.

```bash install.sh```




You will be prompted to insert a domain and the real IP address associated to it so net-Shield will configure for you the first proxydomain (you can see the changes on /etc/nshield/nshield.conf).




### Proxy Domains

To configure proxydomains you need to enable the proxy option on /etc/nshield/nshield.conf (proxy = 1) and be sure that the proxydomain list (on the same conf file) is correct:





```

proxydomains = [

  "sami.pw 8.8.8.8",

  "example.org 1.2.3.4"

]

```




### Usage

After you completed the install with the quickstart script you can call the "config-nshield" commad that will read the nshield.conf and re-configure shield rules based on the new configuration.

Example:

I want to enable SSL on sami.pw that i just configured as above:

1) Edit /etc/nshield/nshield.conf and set autossl = 1

2) On your terminal run: ```# config-shield ```

3) You can now see the changes on the Nginx configuration

The domain must point to the net-Shield instance otherwise will fail let's encrypt verification.

Logs are diplayed on: /var/log/nshield.log

## How it works

Basically this script is set by default to run every 30 minutes and execute these operations:

- Get latest Bot,Spammers,Bad IP/Net reputation lists and blocks if those Bad guys are attacking your server (Thank you FireHol http://iplists.firehol.org/ )

- Enable basic Anti-DDoS methods to deny unwanted/malicious traffic 

- Rate limits when under attack 

- Allows HTTP(S) Proxying to protect your site
