SSH to a remote station without port forwarding on the mac

I would like to SSH onto a remote linux computer from the internet at school, which does not support port forwarding.

I type ssh root@<myipadresshere.com

but of course it fails.

Is there a way to SSH to my remote server using any network I am connected to without the ports being forwarded?

If I type SSH -A root@MyIP , it times out.
