Reach self hosted server from LAN

Hello, I had this problem for a while and finally I found how to fix it, so I will upload the solution here (Lo iba a poner en serverfault.com, así que lo hice en inglés, siempre se podría traducir… :).

I have a self hosted server with Apache2 pointed with the domain example.com. I have also some virtual servers http://www.example.com, cloud.examle.com, etc.

This server is in my LAN, and when I try to access to my server within the LAN throw http://www.examle.com y get my router’s configuration page. From outside the LAN http://www.example.com and cloud.examle.com works properly. From inside the LAN 192.168.1.33 (server internal IP) shows the default webpage (www.examle.com), but I can not get cloud.examle.com
I also have a LAN name server in 192.168.1.33 with bind9.
