The following steps may not be the most direct but they should work for you.
1. go to xfinity.com/myxfi from either within your Xfinity router 2. log into your xfinity account if prompted. 3. click next until you get to the Xfinity Overview screen 4. Click Network 5. Under network Devices, click the > chevron 6. Scroll to bottom of web page and under More >> Advanced Settings click the > chevron. 7. Click the > chevron 8. You now be on the Port Forwarding page. 9. click the add Port forward button if no entries are listed, or, click the edit/add buttons if there are entries already listed.
Note: https://internet.xfinity.com/network/advanced-settings from your browser should take you directly to the page in step 5 if you are already logged into your Xfinity.com account.
Yes, this is very clunky and user unfriendly and I wish Comcast would just bring back the Admin console.
Hope this helps.
