SMB port 445 blocked? Port forwarding in router not working



After many attempts at port forwarding SMB2 on port TCP 445 I stumbled across this support document -


Does this overide my port forwarding? If so, can I get the block removed? I have a very unhappy group of users who are expecting to remote access their File Server via SMB.

 Hello, Barry, thanks for taking the time to reach out to us over forums. I apologize, it does not look like there is a way to unblock TCP 445 or any other ports that Xfinity blocks for security purposes. I know this can cause an inconvenience but our aim is to provide the best possible service while protecting all of our customers the best that we can at the same time. If I was in your same position I would consider using a VPN or any other resources that allow to remote access into your server. If you have any other questions outside of this matter please let me know.
