Hello @Hydekholin,
Your concerns are important to us and I would like to help. There are ports that we have blocked to protect our network for us and our customers. I have included a link that lists all of the ports that we have blocked. You are able to look up how to set up port forwarding on the equipment online or on YouTube. If you have any questions. Please reach us on Twitter at @CoxHelp, visit us on Facebook, or email us at cox.help@cox.com. Provide us the name on the account with the complete service address with a link to this thread so we can get started.
