Answer 1

To "forward" the port, you need the corresponding rule (dstnat) in the NAT section + the rule by which return traffic will go, for example, srcnat or masquerade in the same place

Answer 2

You probably typed the code in Windows-1251 encoding? Try to type the same code in UTF-8 and you will succeed.
