Connecting to my SVN server using HTTPS

Connecting to my SVN server using HTTPS

I'm trying to set up my SVN server on Ubuntu 12.04 so that I can access it
with HTTPS instead of HTTP that I'm using now.
I've tried to set it up with HTTPS, and it works with a local connection.
I can also connect to it with my public IP address, when I'm in the house.
I've port-forwarded port number 443 to my server's local IP address, but
when I try to connect to it from outside my house, it won't work.
I have OpenISS installed and configured with my Apache2 server. So my
question is, is this fixable and do you need to see my setup files before
you can help me? If so, just tell me and I will add it to the question!
