If the device is used as a router, it is able to connect IP terminals from the network with a non-public address to the public Internet. For this, NAT (Network Address Translation) is necessary. Additional configuration is required on the different IP interfaces (e.g. ETH, PPP, etc.) to define on which interfaces the public and on which interfaces the private network is accessed.
| Enable NAT | If this checkmark is set, NAT is enabled. Without this checkmark being set all other NAT settings are without effect. |
| Default forward destination | If all incoming data packets from the public network are to be forwarded to a particular private IP-Address, the destination IP-Address must be entered here. |
| Port-specific forwarding | To be able to address several internal destinations, different port number numbers are assigned to IP addresses of the internal network here. |
