This will have to be a different constructor, such as NewSSHTunnelWithPort. Unless there is a special reason why the called needs to provide a specific port, it's much cleaner to allow hide that.

Is "warm" means to be "warn"? Is so it's not a warning because it will break the connection. How about "io.Copy local to remote failed: %s"

You are closing both connections twice.

There are a few things I don't like about this:
- This is unlimited retry. There must be a way to configure it or give it a save default (such as 3 times).
- It's repeated code, the same thing happens below. The retry mechanism can be moved to be a method.
- There's no need to print the number of failures if you have already logged each failure.
