Port forwarding has stopped working on my arris bgw210-700
I am having the same issue as many others. My port forwarding was set up in Oct 2017 and has worked like a charm for my security cameras until a little over a week ago. I have factory reset the router, forwarded the ports again,
The ports stay open briefly then shut down again.
It appears you guys had a firmware update that broke port forwarding. Please helps me fix this or my security cameras are useless.
