Campaign Creations

I can connect to battle.net.
I can connect to other peoples games.
BUT
People can NOT connect to the games I create 

I've looked into my firewall, settings, etc.  Even my router.  Nothing has worked.
I've even tried turning my firewall off completly (for a short time to see if people could join) but, still nothing.

Now I've moved and I'm at college running off of their network.  But the same problem persists. Any ideas?

EDIT when I port forwarded, I opened 6112-6119 TCP and UDP

Have you tried it direct from the model without a router in between?

No but now that I'm at college I can't :/
If it's anything to do with their router I'm screwed.
I surfed the internet for a while and I even found a "Why can't people connect to my games" FAQ which said it was either my firewall or I needed to setup a static IP and forward the port 6112 UDP and TCP.  I didn't have a static IP address before so that is probably what it was at home.
And after realizing that, I'm pretty much screwed here at college. Lol well thanks anyway.

Yeah, you can't actually port forward at college, you'd have to ask the techs there to open the router ports themselves, which they likely wouldn't. Sorry for the trouble, at least you can still join games- Some people aren't so lucky.
