Hi, welcome to the forum.
From your description, it's unclear what the problem is, though running Broadwave should not interfere with normal web browsing.
From what you are saying, perhaps you are trying to connect to broadwave from a PC on your local network using the public IP address - this will only work if you router/modem supports "NAT loopback" - and many home routers don't.
Have a read of some of my earlier posts about port forwarding , NAT and so on, and come back and let us know exactly what works and doesn't.
