I just did a few unsuccessful login attempts to the neighboring IP (96.30.62.147), and now I can't get access via http or ping (I was previously able to).
All I would have to do is keep reconnecting to Orange to get different outgoing IP addresses, do a few more unsuccessful login attempts, and voilà- the situation would be replicated: that host would be inaccessible to those Orange IPs.
