What is the difference between 1:1 NAT and normal NAT?



  • Dear GuRUs, What is the difference between 1:1 NAT and normal NAT? Would you please give an example?

    Thanks!!

    Best Regards,



  • normal nat (portforward) is just a single port or a portrange of a specific protocol inbound. 1:1 means that all ports and all protocols are forwarded inbound and outbound to that IP. Both variants still need firewallrules for traffic to pass of course.
