New Then it has to be packet rejection on the Linux machine
Spoofing protection (IOW allowed clients on the private side) on the outgoing is forcing things not right.

Or, to put it another way:

making sure who you are and who you claim to be is the same thing. From an ARP perspective and packet mangling. Usually an "interface rule"
