Having those ports exposed to the Internet is scary. Comcast is right in blocking them.

If you really need them, you'll need to use some sort of tunneling mechanism, ie PPTP.

135/137/139/445 has seen widespread filtering since... errr.. 2000? I know it was widely done back in those days when people were connecting their computers directly to the bridged modem/ETTH jack and things ended up in the newspapers that peoples files were available on the Internet because they didn't set a password on their windows share.... or when versions of Windows were pwned during installation of Windows because... Windows.

And expect your SSH DSA keys to require a workaround, or just generate new ecdsa and RSA keys.

Sorry, brain-keyboard output meant to say: ED25519

[-t dsa | ecdsa | ed25519 | rsa | rsa1]

macOS sierra inherits this as it provides OpenSSH 7.2.
