Those other servers probably use TLS or plaintext connections. stunnel
uses TLS, but ssh/sftp use a slightly different protocol that may
possibly be distinguishable by a determined ISP.

I would think that using stunnel to tunnel SFTP/SSH would be possible,
though not strictly necessary. I suspect some other problem is
preventing you from succeeding.

Can you be more specific about exactly what you did for configuration?
Port numbers, specific things you did, etc? You don't have to disclose
your public IP address, but perhaps give the local IPs of your router
and home server, etc?
