GeoIP Block NGINX Ubuntu 20.04

Block or filter IPs based on location in Nginx (tested on 1.18.0) on Ubuntu 20.04.

Install Nginx modules

To make use of the geographical filtering, we must first install the Nginx GeoIP module as well as the GeoIP database containing the mappings between visitors’ IP addresses and their respective countries. To do so, let’s execute:

$ sudo apt install libnginx-mod-http-geoip geoip-database

### HOW TO USE
### Pre-req:
### - run on a Proxmox 6 server
### - a dhcp server should be active on vmbr1

Generation of a Self Signed Certificate

Generation of a self-signed SSL certificate involves a simple 3-step procedure:

STEP 1: Create the server private key

openssl genrsa -out cert.key 2048

STEP 2: Create the certificate signing request (CSR)

openssl req -new -key cert.key -out cert.csr

Ignore all that craziness below.  These can be set from the cli with the "pritunl" command.

The commands below can be used to get/set the values of the cert, key, port and if the :80 -> "app.server_port" redirect is active.


# Get current SSL server cert:
pritunl get app.server_cert

# Get current SSL server key:
pritunl get app.server_key
