Ports closed after firmware update

Hi all,

 

I think my Modem was updated by Spectrum (V2.01.18) recently and now a lot of my devices that I remote into are not available. I called Spectrum support and they said that they don't block ports and I should contact the manufacturer and they should be able to open the ports back up. Seems like all my ports except for 8000, 8080, and a couple others are open. The rest are closed. I couldn't find any posts here. Has anyone gotten this problem? Any fixes?

 

Thanks

    Do you have any port forwarding rules setup?

      Yes, I have always had the ports I needed forwarded. I tried having PNP on and off, deleting the port forwards and redoing them, restarting the c6300.

      All the ports were working and I did not change and settings on either c6300 or devices I am trying to remote into. When I went to look I noticed the firmware version looked different and it must have been updated and it broke my ports. I checked on various sites that scan ports and all but a handful are closed.
