As many others we are having problems with clients connecting to our server through a firewall. We have made all the recommended changes to allow tunnelling. After many tries I think the problem is that the initial connection is tried to be established on port 8081 and not port 80. This is not described in the manual on enabling tunnelling, and to my understanding this is not a true tunneling because a lot of people simply only allow traffic on port 80. I have tried to change the connectivity for both port 1533 and port 8081 to port 80, but then everything fails on the server.
