Network Interface | Configuration | Port Forwarding

Port Forwarding is required when NAT is configured. NAT translates all internal addresses to one
official IP address (WAN IP address). With port forwarding enabled it is possible to access internal
services and workstations from the WAN interface.
Port forwarding forwards TCP or UDP traffic trough the P560 controller's local port to the specified
remote port. Use the network interface | configuration | port forwarding menu to specify such a
port forwarding rule. By default no port forwards are defined on the controller:
Figure 52 – Port Forwarding Rules
Click the new button to add a port-forwarding rule:
Figure 53 – Add Port Forwarding Rule.
Status – select status: [enabled/disabled].
Type – select type of forwarding traffic: [TCP/UDP].
Local IP Address – P560 device interface address from which the selected traffic should be
forwarded.
Local Port – P560 device interface port from which the selected traffic should be forwarded.
Remote IP Address/Port – internal IP address and port no (LAN ports) to which the selected traffic
shall be forwarded.
Example:
Create rule as follow:
Type = TCP, local IP address/port = 192.168.2.248:8080 remote IP address/port = 1.2.3.4:8080.
With such a rule all traffic coming to port 8080 on the P560 interface local address 192.168.2.248 will
be forwarded to port 8080 on the server (host) 1.2.3.4.
Port forwarding is limited to 255 rules.
