Red Dead Redemption 2 Online connectivity issues. Open port help?

I called Red Dead Redemption 2's tech support after I stopped being able to connect to the PS4 online game. R2 support said I should call Cox and have them open the below ports to help. If I call Cox, will they actually open these ports for me? I have my firewall set to Low so that no services are restricted.  In Advanced options, I have PPTP and UPnP enabled. Is there a way for me to open the ports myself?
