Huh, that sounds dubious.
Dynamic NAT for standard users to access the outer world, that's ok, but
why NAT for access of internal resources?
In a local network or VPN there's no need for NAT, because the private
address space you're probably using is well known inside the organization.
Seems to be just another example of weird stuff admins are inventing for
some not-so-well understood reasons.
Additionally, a NAT gateway may not reshuffle its ports/addresses for an
existing connection, which seems to happen here. I'd call that a bug too
(the firewall vendor will probably call it a feature, "look, we're
scrambling the ports to obfuscate data origins..." - well done!)
However, glad you found a workaround.
