Before connecting with NordVPN

Do the following before activating NordVPN on VPS machine such as linode or you will lose connection via ssh.

if ssh connection lost, you have to connect via LISH console in linode's Cloud Manager, to login, provide a user and password that's on that VPS system.

  1. $ nordvpn whitelist add port 22
    if hosting website, add port 80, 443 as well

  2. set up ip route, example ip 11.22.33.44, reference
    $ sudo ip rule add from 11.22.33.44 table 128
    $ sudo ip route add table 128 to 11.22.33.0/24 dev eth0
    $ sudo ip route add table 128 default via 11.22.33.1

other useful commands:
$ route -n
$ ip route show
$ ip rule show

to update values, use 'change' instead of add

  1. connect NordVPN $ nordvpn c
  2. show current IP $ curl ifconfig.me or $ nordvpn status

#
use nordvpn whitelist instead

(optional) to disallow traffic from all other ports, set up iptables as follows

$ iptables -A INPUT -d 11.22.33.44 -p tcp --dport 22 -j ACCEPT
$ iptables -A INPUT -d 11.22.33.44 -j DROP

#
