PortForwarding
Port forwarding is active only in Router network mode..
Port Forwarding, UPnP and DMZ is effective only if NAT is enabled.
The Port forwarding section gives the ability to pass traffic behind an interface that has NAT enabled.
For instance if the unit is in router mode with NAT enabled on the WAN interface, no devices on the
outside of the WAN interface can see any private IPs on the LAN side of the unit. By using port
forwarding or DMZ it is possible to pass traffic through to these private IP addresses.
Figure 51 – Port Forwarding Configuration
Enable UPnP – select to enable UPnP (Universal Plug and Play connectivity) service. The UPnP
enables APC communicate with other network devices automatically opening required ports, without
manual intervention.
Enable DMZ – select to enable DMZ. DMZ opens all TCP/UDP ports to particular IP address. It
allows setting up servers behind the APC. The feature is used commonly for setting up VoIP or Multi-
Media servers.
Public port – specify the port that will be accessed externally using the public IP address.
Private host – specify the IP address behind NAT that public traffic will get forwarded to.
Private port – specify the listening port on private computer behind NAT.
Protocol – select type of forwarding traffic: TCP or UDP.
