I don't think firewall can make a difference. I can host even with my firewall settings on High. But, i'm using ZoneAlarm so, maybe this does not happen with your firewall.
EDIT: Or try Nydedrigan's way.
NydedriganWell, if you have linksys (router), then you should do this...
Open your Internet Browser.
Type in the address bar> 192.168.1.1
This will access your router, and then you'll put in your password which would be...something. lol,
For me its no login name needed, but just password. So, once you get your password, click on the Applications and Gaming, then enter in the port 6112 under "Start" and "End" fields. ((Don't forget the Application name "wc3" then select Both under "Protocol" then under IP Address put the number of your machine is. You can get that information from your local area connection computer thing at the bottom right side of your window. Right click that then "Status", then click "Support" and your IP number should be next to the "IP Address".
Other words you should see something like this in there
192.168.1.100 192.168.1.101 192.168.1.102 192.168.1.103 and so forth...which ever yours is then place that last three digit numbers in the "IP Address" field in the Linksystem under "Applications and Gaming". Once done
Check Enabled, then save settings. Enjoy!

It could be possible that you can host i have found with my router that because it is a NAT i cannot host i have tried numerous times to get it but after searching the net i found that i cant host so all i can do is get another router. So just keep that in your mind that you might not be able to host. And ive tried to convince my dad to get a new router but hes a pain in the butt and just ignores me lol.
I dunno, I don't think I, myself, have a linksys, or that I'm going through someone elses router, I dunno about the bad router thing, but I'm pretty sure that's not a problem, and I have a firewall, but I turned it off and it still didn't work, it might be worth noting that I only have this problem on Battle.net, I have no problem with Local Area Network.
