Repka or ATAG and others do not have this issue. A guy at sukhoi.ru who had same issue wrote:

Технологию не знаю, ибо балбес.

Translation:

There is a solution. The issue is that your provider allocated IP for you but not a right gateway. A friend of mine who is good in IT changed my internet settings from "auto" to what was needed and changed preferred DNS of the server. This fixed the issue. Do not know details as I am not an IT guy.

Try contacting your provider for correct gateway and DNS settings for Steam server or invite a good IT specialist to fix the issue.

I started to have this issue at my home PC only after I stopped paying my provider for a so called "external" IP. Now I have only internal LAN IP and can host only in Lobby but not in Server section from my home PC.

Regarding firewall: when I had an external IP I still could not host when I changed existing rules in Avast firewall. I had to completely delete the old rules for both Steam and CloD and create new rules for them which were absolutely empty (allowing all and every connection). Only after this it worked. As BigRepa mentioned CloD makes a lot of outgoing connections that must not be blocked.

PS. Also try searching and asking in the MP section of the forum. Some server guys who may have a solution do not read this section.
