I often setup not only multiple fake hostnames in my .ssh/config but I also setup multiple remote files under any given repository's .git/remotes directory, using one file per fake hostname.

That way I can pick which options to apply at the time of git push or git fetch by just changing the name passed to it.

	$ ls .git/remotes
	private public

	$ cat .git/remotes/private
	URL: private.host.com:/path/to/repo
	Pull: refs/heads/master:refs/heads/origin

	$ cat .git/remotes/public
	URL: public.host.com:/path/to/repo
	Pull: refs/heads/master:refs/heads/origin

	$ git push private
	$ git fetch public

I often need this to traverse around firewalls and whatnot. It works pretty well, assuming I can remember where I'm currently connected to. :-)
