There are firewalls that are partial which I noted in the CNET Network Forum but sorry no, I've found this to either just work after we change the router a little or never work. Samsung's apps are just that bad at times.
Try this. Back to the store that sold this and have them demo the product. if they can't you have a good reason for a full refund.
I just got done with Samsung live support after spending a week on the forums here. I assumed I had firewall problems because I could not connect my iPhone 5S to the Samsung Smart TV through the Smart View 2.0 app. The TV appears in the device list, I can enter the PIN and then it immediately disconnects. However, I have an iPad 3G that does connect through the same network. The support chat person told me to talk to apple support about why my phone would not connect. I would rather poke my eyes out. I was wondering if anyone else has a solution to this problem? Do I need to change a setting on my iPhone 5S to let it communicate with Smart View 2.0? I did verify that this is the correct app for the TV. Again, I can use that app with my iPad 3G.
