R7000 port forwarding not working on PS4

   Firmware version?

   So, the WAN/Internet interface on the R7000 has your public IP
address?  What are its first two octets ("a.b" out of "a.b.c.d")?  (If
the R7000 is hidden behind another router, then port forwarding by it

may be doomed.)

   The alternative to configuring your (unspecified) "a Xfinity gateway"
in bridge/modem-only mode would be to configure the R7000 as a wireless

access point.

   What are the actual port-forwarding rules?  Copy+paste is your
friend.

   Is that a true static address (configured on the PS4), or a reserved
dynamic address (configured on the R7000)?  What is that address?  Have
you verified that the PS4 is actually at that address?

   I'd assume so, but more info should permit accurate blame assignment.
