PRIVATE ADDRESS MODE

Choose ANY INTERNAL (default) or SPECIFIED to choose which address to use for the private address. The private IP address can be specified to filter certain protocols and ports to specific servers in the private network. Likewise, internal hosts can be steered to certain servers on the public network. A new request from the public network that matches this entry’s public parameters is dropped if the PRIVATE ADDRESS MODE is set to ANY INTERNAL (with the exception of protocols that the internal router is expected to respond to, such as ICMP or SNMP).

PRIVATE ADDRESS

This menu appears when the PRIVATE ADDRESS MODE is set to SPECIFIED, and allows the user to enter a specific private IP address for this translation. Packets destined for the public IP address (of this translation) are redirected to the private IP address specified here.

PRIVATE PORT MODE

Select ANY PORT (default) or a SPECIFIED port number for this translation. The private destination port associated with this entry can be specified to provide more control over certain types of traffic. Leave configured as ANY PORT to cover all port types.

PRIVATE PORT MODE

This menu appears when the PRIVATE PORT MODE is set to SPECIFIED, and allows the user to enter the port number that replaces the public port number during the translation of incoming packets. Outgoing packets from the private address space that match this protocol are sent to the specified public address and port, if any.
