Of course as ever: If you've got a server under your control you can
manipulate everything which happened before (and at) this server. So
far so true. But you didn't tell that you've control over server.b.

Please enlighten me: why?
For security reasons? This would be so called security by obscurity
which is known to be no security.
It's a little bit like blocking ICMP echo/reply messages. This indeed
closes a hole which can be used to tunnel malicious data through a
firewall but on the other hand you can minimize the risk by also
filtering "oversized" ICMP echo/reply messages and other things.
But if you block ICMP you harm others which not so seldom need this
"tool" to troubleshoot thing. And these others are your partner "in the
internet".
So carefully think about whether or not this really helps you and also
think about how this personal measurement harms other participants of
the internet.
