Both seem to be defaulted.

On 6.1:

  $ egrep -C 2 X11Forwarding /etc/ssh/sshd_config
  #AllowTcpForwarding yes
  #GatewayPorts no
  #X11Forwarding yes
  #X11DisplayOffset 10
  #X11UseLocalhost yes

On 8.1:

  $ egrep -C 2 X11Forwarding /etc/ssh/sshd_config
  #AllowTcpForwarding yes
  #GatewayPorts no
  #X11Forwarding yes
  #X11DisplayOffset 10
  #X11UseLocalhost yes
