Question

BeerMan is correct, the router part of the 'modem' is the key. You will need to map the messages recieved on the various external router ports to the same internal ports on the IP address your roxio streamer grabed from your DHCP when it started (unless you assigned a fixed ip on your internal network for it).

 

There may be one fly in the ointment though. Roxio has decided that their streamer was going to use the standard port 80 and give you no way to alter that port. ComCast, Cox, Verison and may other ISP providers block port 80 for most residential users. That way they can charge 'Business' customers more for service that allows port 80.

 

You should check with Comcast and see what ports they allow and what they block.

 

In anycase let's assume port 80 is blocked by your ISP, what to do?

 

Well one thing you can do is map a different external port (one that is not blocked) to your internal port 80 (used for HTTP protocol). Map the others as directed.

 

Also, while you are there, find out what your 'external' IP address is. This is the IP address assigned by your ISP to your cable 'modem'. This can change over time so you would need some sort of Dynamic IP address mapping provider if you don't like typing numbers...

 

Then when you get on a computer outside your home network you would type http:\\yourexternalipaddress:externalport and you will get the login page for your streamer.

 

For example, lets say your exteral IP address is 90.12.144.45 and you pick external port 8090 to map to your internal port 80. You would type "http://90.12.144.45:8090" to get to your Roxio Streamer. Of course inside your home network you would only need to type the IP address that Roxio Streamer has grabbed because inside your home network you are on port 80 (not the external one you picked).

 

 

I am very disappointed in Roxio for the regidity of their port mapping and the total lack of documentation for the Customer.

I opened all the ports as directed. When I am on the same network as the server everything works great. When I am at another computer outside the network I can get to the Streamer sign on screen OK but when I attempt to sign in I get "DNS Error - Server cannot be found."

I also tried to assign a different port to internal port 80 and that didn't work.

Any suggestions?

Check what IP address the software is looking for

 

On my machine I had allocated a fixd address (192.168.11.101) but the software was looking for 192.168.11.4. A quick change on the computer and resetting the NAT to .4 got it up and running.

 

Why it won't take the allocated IP number on a LAN is something I still haven't understood

OK I deleted the Streamer and reinstalled it. Now when I attempt to sign in outside of my network with the network name, my sign on name and password the sign-in screen refreshes, the fields are blank, with no error message.
