Only if you launch your campaign in CLOUD mode. If you launch in LAN mode Smiteworks doesn't have anything to do with connections. I just launched a campaign in LAN mode with my router disconnected from the Internet and connected with a demo client running on my laptop, also disconnected from the Internet.Smiteworks maintains the connect site.
If on the other hand you mean Smiteworks manages the cloud connections if you so choose to host your remote players that way - that's correct.
