Thanks Ola.
Actually, I want to do this NAT through the interface.
Senario: public ip /32 on interface and private ip belongs to my LAN segment.
Please advice.


Isn't that about exactly what the Juniper-example does?


set security nat static rule-set MY-RULE-SET from zone untrust
set security nat static rule-set MY-RULE-SET rule RULE1 match destination-address 202.101.83.50/32 set security nat static rule-set MY-RULE-SET rule RULE1 then static-nat prefix 10.10.10.80/32

If 202.101.83.50 is set on the wan-interface, you do not need proxy-arp

Adjust security-policies as needed:

set security policies from-zone trust to-zone untrust policy permit-all match source-address 10.10.10.80 set security policies from-zone trust to-zone untrust policy permit-all match destination-address any set security policies from-zone trust to-zone untrust policy permit-all match application any set security policies from-zone trust to-zone untrust policy permit-all then permit

set security policies from-zone untrust to-zone trust policy server-access match source-address any set security policies from-zone untrust to-zone trust policy server-access match destination-address 10.10.10.80 set security policies from-zone untrust to-zone trust policy server-access match application any set security policies from-zone untrust to-zone trust policy server-access then permit

Of course you also need to modify the name of your security zones and rule-sets and rules to suit your setup.

    It is pretty straight forward:
