What is the difference between tcp/ip and ssl

Just because it's almost always done that way, it's not a requirement. Most network equipment should pass it ok unless there's some kind of filter rule in place to block unexpected protocols. The operating system is the big problem, you have to implement a nonstandard protocol via raw sockets and your own frame handling code, without any of the help and security the OS normally provides.

Something like a NAT wouldn't need it, and you could probably dodge it if you can encode the flow identification in to the IP headers. There is no solution without remapping ports not to clash.

Note that I'm assuming you only have one, or a small number, of public-facing IP addresses; if that's not the case you don't need NAT.
