You want to implement Static Destination NAT in order to provide external, Internet users access to an internal Web Server that has a reserved (RFC 1918) IP address. You have an unused valid IP address on the network between your Security Gateway and ISP router. You control the router that sits between the firewall external interface and the Internet. What is an alternative configuration if proxy ARP cannot be used on your Security Gateway?
