I would no longer recommend port knocking using a static port sequence. Instead, I'd recommend knockknock by moxie, https://github.com/moxie0/knockknock/blob/master/README
I have discovered knockknock project just little before finishing the post and I really liked the reasoning behind the project, I will try it. However I was almost done with writing the post and I though it could be useful nonetheless because you do not need any additional software to set it up.
One thing concerns me is that it seems that knockknock is unmaintained at the moment (no commits since 3.5 years).
