DNS Server Setup

Setting up Iodine requires control over a domain, for which you have to register the following dns records.

You have to run your own server with a public IP that will function as nameserver for your domain “mydomain.com” managed by iodine.

Assume you have a domain called “mydomain.com” and it’s IP is “1.2.3.4”. You have to register a subdomain, e.g. “tunnel.mydomain.com”. Also, you need another subdomain “ns.mydomain.com” for your nameserver. For the tunnel subdomain, Iodine on your own server (1.2.3.4) will pretend to be the authoritative nameserver.

So you need to create an A record for the sub-domain (tunnel.mydomain.com) that point to IP of the private server.

dns IN A 1.2.3.4

And you need a NS recod that makes the dns sub-domain the authoritative name server for the tunnel sub domain.

tunnel IN NS dns.domain.tld.


A ns points to 1.2.3.4 NS tunnel managed by ns.mydomain.com

Iodine Server Setup

install and start iodine

$ sudo apt install iodine

$ sudo iodined -c -f 10.0.0.1 -P 123456 tunnel.l0m.de

Test server

Iodine Client Setup

install and start iodine

$ sudo apt install iodine

$ sudo iodine -f -P 123456 tunnel.l0m.de

Test tunnel

$ ping 10.0.0.1

Set up routes to go through the tunnel

Find out dns server: $ rnmcli dev show | grep DNS

Find out gateway: $ rnetstat -rn|egrep "^0.0.0.0"


Find out your tunnel interface: ifconfig -> look for something like dns0 that wasn’t there before

$ route del default $ route add default dns0

and if dns server and gateway don’t have the the same IP adress anyway:

route add -host [DNS server IP] gw [gateway IP]
