Only thing I see to be missing here is actual Class B address space 172.16/12 but instead you are trying to forward from Class A public address space assigned to FACEBOOK. I don't quite think you will get that to work... That is unless you are the Facebook authoritative server...
range: 172.0.0.0 > 172.15.255.255 range b10: 2885681152 > 2886729727 range b16: 0xac000000 > 0xac0fffff hosts: 1048576 prefixlen: 12 mask: 255.240.0.0
Was this just an intentional obfuscation ?
