| + | ==== NAT ports usage ==== | ||
| + | |||
| + | To perform NAT (Network Address Translation), source port numbers on outgoing packets are modified. | ||
| + | These numbers are selected from a pool of non-well-known port numbers. | ||
| + | This port number range can be configured by the fields **Port start number** and **Pool size**. | ||
| + | The default values should not be changed other than possibly in the [[network:operational_modes#WAN SIParator 1|"WAN SIParator 1"]] (single address [[advanced_network_configuration#Bridge (802.1D) WAN to ET4|802.1D bridge]]) mode, where there is a risk of conflicts with another router/firewall also doing NAT.
