Reference10:Linux/NAT
Use of NAT (Network Address Translation) for the relevant interface can be enabled here. It is also possible to exclude particular network addresses and masks from the translation.
| Include Interface in NAT | A checked check box enables NAT for the interface, providing NAT was enabled in general under chapter "IP4/NAT/General". In other words, the network connected to ETHn is regarded as external unless it was excluded under Exclude Address/Mask. |
| Exclude Address/Mask | IP network that should not be included in the Network Address Translation. |
