Sure, you do. However, the intersection between the set of protocols my internal clients speak with each other and the set of protocols allowed to leave the network by the firewall equals to SSH only. And I have SSH configured with StrictHostKeyChecking, so I see no danger. > I know you well enough to know that you almost certainly Got It Right.

I just oppose to the overgeneralised claim that RFC 1918 in external DNS == Bad. It's a bad idea unless you know what you are doing. And I claim the latter. -- Martin F.
