When configured for NAT, the Pipeline does not respond to the "assigned"
address for Telnet - even if that "assigned" address is a static one. It
assumes all incoming packets are to go through the NAT table.
You can however use the internal static mapping to force this - if it's
necessary?
You could still assign them a static IP address as a /32 and have this
work....unless I'm missing something in your requirements.

Why do you need to "see" the Pipeline to get this to work?

Is the server using the *other* IP address you assigned in the /30
subnet? Ohmygod....that's confusing....I think you can solve all of this
by simply assigning them a single IP address /32, and mapping SMTP etc
to the *internal* address of their mail server.
