No, there are no such settings.

no, because as I said in my original message, I **can** do ssh traffic. I
am doing it right now, on the other Centos server. It is only one of them
that became unreachable.

of course I can't do it right now, exactly because... I can't connect to
the server. But I will pass along these and all other similar suggestions
to the VPS provider help desk, since they will surely save time, so thanks
for these and any other tips that may come!
