Either I failed before, or something happened during my tests. My success-mail might have been a bit premature, since I can't get it to work now at all. One of the machines is the def-gw of the other usually, so I might have mis-configured it to not use the tunnel somehow. 8-(
I was about to test ssl, and didn't get it to work. Then I thought I'd go back to unencrypted tests and they didn't work either.
