So I've been using portfowarding for at least a year now and after I changed my motherboard on my computer port fowarding just flat out doesn't work. I tried disabiling ipv6 but that didn't work (one of the screenshots show that I cannot connect to ipv6 things). I don't really know what else could be wrong Xfinity guides are never really that helpful at all.
Hello YesARealPerson2. Thanks for visiting and posting on our Forum. We have not changed any rules or modem configurations to prevent your port forwarding from working. Since you have changed your computers motherboard, you may also need to change your port forwarding rules. We recommend you contact the manufacturer of the motherboard for further guidance.
Please let us know if you need help with anything else.
