8.1.5 Configuration Examples for Port Forwarding
8.1.5.1 Example One
An organization wants a LAN server (IP Address: 192.168.16.88) to open syslog service
(Protocol: UDP; Port: 514) to the outside users. And the Device will use 2514 as the
external port and the WAN1 IP address (200.200.200.88 in this example) as the external
IP address. Then all the requests for syslog from outside users to 200.200.200.88:2514
will be forwarded to 192.168.16.99:514.
The following figure shows the detailed settings.
