They should be able to attach 2 modems to your account and then assign each one a IP address no setting would need changed in the modem.

I finally did get this answer from Xfinity. You basically need a cable modem for every public IP you want to use.
you may want to double check with Xfinity.
at some point of time, they were selling extra public IP for $5-10/month.
you can always go for business connection with multiple IPs with CM700 (although it will NOT be STATIC IP).
