In the Local IP Address field, enter the IP address of the server on the LAN to which you want traffic redirected.

For one-to-one NAT, this address is the LAN client address.

For the Public IP Address, either:

•Select Use External interface IP address.

•Select IP Address. Then, type a public IP Address that is different from the X family device public WAN IP Address.

This option can only be used if you have been provided with multiple IP addresses. You must select this option for one-to-one NAT.

If you want a default port number used by the service to be translated to a different port number by the X family device, check Enable PAT and enter the port number you want in the Local Port field.

Note The Enable PAT checkbox and the Local Port field are disabled if you have selected ALL from the Service drop-down list.

Click Create.

Click Cancel to return to the FIREWALL - Virtual Servers page without saving the changes.

Note Virtual Server traffic is subject to firewall rules. You must set up a firewall rule to allow the traffic for the desired services through the firewall. To allow incoming traffic, use the IP address, or the zone containing the IP address, of the LAN device as the destination address of the firewall rule.
