port forwarding

@XfinityMatthew​  Yes, I have tried that many times, as have many other posters, which you can verify by looking at port forwarding threads.  It simply does not work.  The tool says the ports are being forwarded, but they are not.  The only port I can forward is port 80.  This bug is well-documented, and xfinity needs to fix it.  

I worked on the phone with a supervisor and we could not get it to work, together (tried 6 different possiblities, none worked).  Ultimately he suggested that I create a DMZ (which also did not work).

You should try what you recommend, then use an open port checker to see if the port is open.

I would be happy to work with xfinity to show them how the tool fails, if they are interested in fixing the bug.

@user_317kmi​ Thanks,  I just saw your message.  I sent the DM, I think.  There doesn't seem to be a confirmation that it actually went out.  I pressed the "send" icon, so I think it probably went out.
