On OVH's Firewalls

OVH Hardware, support and pricing is GREAT! Buuuuutttttt...

Their firewall situation is not. Guess what, if you use the supplied firewall, any server from any other customer in the local NOC that your server is in, can connect to your server. They seem to be all "safely" behind the OVH firewall product.

You have to protect each server individually with its own in-machine firewall.

I don't want to automatically trust all other OVH customers.

At first I thought I was doing something wrong (more than a decade of setting up firewalls). But I did put in a support ticket and they confirmed this.

Maybe I'm wrong, maybe something I did not understand, but damn... If I'm not.... :-(
