It seems to depend on the ip he choses to assign to me. Outgoing sockets work. Incoming sockets dont reach me. Problems began when they started using 84.167.xx.xx for their DSL-customers at the end of 2004. Support does not answer my emails. Maybe they dont even get them. I do have problems sending emails to a lot of places using this ip address range. If I was not afraid that a lot people are facing that very same problem, probably without even knowing, I would not bother you. There are no firewalls between the two computers neither in hardware nor in software and there are no NAT-routers involved either. This is the second trial to send this email.
