Have i done it correct ?

Ok i have installed Comodo IS , by using the guide of chiron.

Do i have to do more ?

I have read a guide from mousse that u have to delete the ‘’ allow all outgoing ‘’ in the firewall or something ?

Or is that already done if i have it in proactive mode ?

It’s already done in Proactive. I would recommend using Proactive and set your configurations up from there.
