Port forwarding on DPC 3825 Cisco Gateway

Why does Cox not allow port forwarding on the Cisco DPC 3825 gateway? You can't even update the firmware because that's under Cox control too. As I see it it's simply a way for Cox to make more money by making you purchase the premium tech support for $100 and so much a month thereafter or a one time $60 to set it up for you. For $180 a month I'm not paying more money. I feel like I'm being ripped off! Here's what happens... log into gateway>applications and gaming>port range forwarding>enter external start and end port, internal ip address, start and end port, enable and click save. Pop up stating "The page at 192.168.0.1 says: the setting of port must between 1~65,535: 0" .  I certainly didn't try all 65535 port numbers but any number I did try didn't work. What gives? Anyone else have a problem with this?

If Cox is saying they can do it for money, then you can do it for free. They don't have any special ability other then knowledge of how to do it. They just don't support that type of thing for free. 

Could you include a screenshot of how you have your port forwarding set up along with the error? What are you using as a range? It looks like its complaining about a 0 in one of the fields.

From the screenshot, it looks like the error is talking about the last line highlighted in red. Not sure if it doesn't like the empty field under "End port" or doesn't like that "Start port" has a 0.  Try just putting a 0 in the blank field? 

If that doesn't work, maybe also try with another browser? Overall though, it doesn't look like a port forwarding block, but a malfunction of the design.
