[ARMA II Server Problems?]

Hello, I am trying to host a fallujah mission today on ARMA II operation arrowhead, using the ACE mods aswell as the CBA mods, I try to put it up but none of my friends can see it. IT was set to internet aswell as their filters. I hosted it off my computer and it is not a dedicated server. It worked fine last night but today it gave me problems when i tried to launch it.. Any help? thank you
