OK, you would need to get an additional public IP address assigned to the modem by Comcast but they are phasing that feature out. I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. We've seen cases here where they have been able to get this accomplished for customers even when it is not listed in their rate cards, YMMV. You should get a reply here in your topic. Good luck !

For non-commercial accounts, xfinity has phased out the ability to get a second external IP address.  There are rumors that they will sometimes allow it, but I have not seen it happen in a long while. 

A far better solution, and one that is far cheaper as well, is to simply buy a router or switch to connect to the modem.  Either of those will give you multiple additional ethernet ports without the hassle of setting up two WAN IP addresses.

Using a switch on a straight cable modem would require multiple public IP addys too.

Thanks @NoNoBadPuppy​ and @EG. I am using a router already with 4 seperate GB ports. The second roter is 2G capable. However recetnly (On Jan2oth), suddenley all GB ports dropped to 100mbps. I was getting > 600G on wifi and close to 950G on speedtest for second router.  I have change 2 cables and also used cable to cat8 cable. Still same issue.  First router WAN is showing 1000mbps bur LAN ports showing 100mbps now.   Thats why thought of connecting to second ethernet port on CM1100.
