This is a rephrased question of What is the simplest way to use svn repository through firewall without compromizing the security?
We need a new svn repository similar to googlecode (gpl, mit, bsd, etc. license; reliable; secure; easy to use; free) but with svn+ssh support. All traffic must be able to be rerouted through port 22 via standard ssh/putty/plink commands.
Reason for this are the strict firewall rules. Opening https port and installing third party software is out of the question. I will accept also "no there is no such thing" answer if there really does not exist any repositories that I am looking for.
edit: added free to the question body. Also, check out: Is it possible to tunnel https traffic via ssh tunnel with standard ssh-programs?
