Re: [Internet] Sagemcom 2864 port fowarding no longer working?!? I have the exact same problem... can't access ports (using external IP address) from within the network. Spent hours and hours trying to figure out why I was getting errors.
My firmware and rescue versions are exactly like yours and I WISH they would advise when they do an update as that would narrow down the troubleshooting.
My ports are accessible using external IP only when outside of my network. I hope we can regress a firmware upgrade...
