Thank you for your reply.
Yes, when I place my Vonage box INSIDE my firewall/router, all is fine. I have my firewall/router configured with the proper ports. It works perfectly. However, when I place the Vonage box OUTSIDE my firewall/router (connected directly to my modem, then the firewall/router connected to the Internet THROUGH the Vonage box), searches produce few results, and I cannot upload or download files. The reason I need to connect to the Internet THROUGH the Vonage box is I want Vonage to have the bandwidth priority. For instance, when uploading/downloading files, sometimes conversation breaks up because the file transfer canabalizes the bandwidth. I want the voice to take all the bandwidth it needs, then hand off excess to the file sharing/computer. So it's a mystery why it works just fine inside my router/firewall, but when connecting directly to the Internet, uploading/downloading doesn't work. ALL other Internet functions work - surfing, email, etc. I have a full connection, but it appears SOMETHING is being blocked.
Thank you again.
