after sometime that my mezzmo server is UP,it becomes unreachable from the web to the people that are outside of my LAN network. After further investigation,I found that the problem is caused by some kind of internal problem. Infact when the server becomes unreachable from outside,it is also for me,that I'm inside the LAN network. Infact if I try to open this site :

it says that can't be reached. I tried to change a lot of settings to see if I was able to fix the problem,but regularly, after a variable period of time, the problem comes again. Do you have some suggestion to give me ? thanks.
