DNSCrypt server with vultr.com

After you have registered at vultr.com and successfully logged in. Click on Deploy New Server.

Then you have to select the location of your server. In this example I choose: Frankfurt

Select Server Type: Application -> Docker -> Cent OS 7

The 5$ variant is quite sufficient

Add the following startscript (type Boot): dnscrypt_install.sh

Choose a server name and click on Deploy Now

Note: This name will automatically be the name of your resolver

The server will restart after a few minutes. Go have a cup of coffee and wait 5 - 10 minutes!

Log in via SSH (the IP address can be found in the vultr. com web interface).

You can find your stamp (and all other keys) here: cat /root/keys/provider-info.txt

Firewall rules can be found here: /etc/sysconfig/iptables

Replace the content of that file with the following lines (or download them here):

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT

-A INPUT -p udp --dport 443 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT
-A INPUT -s 127.0.0.1 -j ACCEPT

-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

Reload the firewall rules: systemctl reload iptables

Enjoy :)
