Again network trouble between the VMs (currently ATLAS) and the CERN network.

My running VMs switched to the spare server cvmfs02.grid.sinica.edu.tw

Unfortunately there are two major problems:
1. That server is "far away" (ping >300 ms), therefore slow
2. Either that server or the VMs are misconfigured
The VMs try to connect to port 80 on the server and get no answer there.
Instead the server answers if I redirect the requests to port 8000.

I mentioned that misconfiguration a couple of weeks ago but my post was obviously overseen.

Just out of curiosity :
- Is anybody at CERN or it's partners aware of the configuration I described above?
- Is that a misconfiguration or should it be as described (then why?)?
