Hello, user_58slgf. Thanks for reaching out through our Xfinity Community Forums. I completely get how frustrating it is when something that was working fine, like port forwarding, suddenly stops. It's definitely not ideal when you're relying on it. 


Our support team put together a really helpful guide that walks through port forwarding setup and common issues. While you're likely familiar with the basics, giving it a quick review might help us pinpoint why your ports are suddenly showing as closed. Sometimes, a small detail can make all the difference! Please take a look at the guide here: https://forums.xfinity.com/conversations/internet/answered-port-forwarding-primer/602da481c5375f08cd7fbf40 After you've had a chance to go through it, let me know if any of the information helps, or if you have any questions. We're here to help!
