savone, it depends on how you interpret the question. If an SSH connection is available outside the VPN and that is what the person wants to use, the server configuration is required to make sure port forwarding over SSH is available.
If ssh is only accessible via VPN, than no matter what changes the person makes to the ssh server, the VPN must be present for the ssh connection to work.

if there is a firewall between me and ssh then can I use port 80 to do ssh login? I am sure firewall will allow port 80 and 443.
