It depends what kind of tunneling you're talking about.

I don't think that will help you. (Subject/object confusion?) 

As Edmund Edgar wrote, you could put your ssh server on a 
non-standard port. If you have multiple IP addresses, 
then you could put your ssh server on port 25/80/110/443 
of a separate IP address, to avoid conflicts with your 
mail or web servers. 

Another technique is to tunnel ssh traffic _through_ http. 
I have not done this stuff. Here's a start:

Good luck.
