Thats good you got a solution!
BUT local is cheaper 
and likely faster and more convenient.
according to this: Conan Exiles Dedicated Server Launcher (Official Version: 1.7.9 / Beta: ----)
" NOTE: If you only wish to play on your home network, without anyone accessing from the outside, you can just bypass all the network port forwarding, and instead of using the External IP you can use the Local IP of the server, which in Steam you can find by looking in the Steam (Top Menu) > View > Servers > LAN to find the locally running server and launch the game from there."
Heres what it looks like with my local server running…
Its a bit sluggish but just keep hitting refresh for a bit and your server (I named mine Tempest_of_Set) will appear in the list. Anyone on your local network should be able to see it listed and connect.
