ForwardX11 yes is the same as -X. You can put it in
/etc/ssh/ssh_config for system-wide client defaults or in
~/.ssh/config for user-specific client default or per host.
But this is a red herring- the real issue is that the server
is not allowing it.
AllowTcpForwarding is for -L and -R opts. Red herring.
-Y is a red herring too- it's just a less-secure -X.
What you want is described in 'man sshd_config' which
shows you how to control the ssh server (sshd) settings:
/etc/ssh/sshd_config .
