Define Custom Service
To configure a Custom Service, choose whether to use Port Forwarding or Trigger Ports.
•
Port Forwarding
forwards a range of WAN ports to an IP address on the LAN.
•
Trigger Ports
forwards a range of ports to an IP address on the LAN only after specific
outbound traffic “triggers” the feature.
Click the
Ne
xt
button.
If you chose Port Forwarding, the Port Range entry screen appears.

Port Forwarding forwards a range of WAN ports to an IP address on the LAN. Enter the fol-
lowing information:
•
Service Name:
A unique identifier for the Custom Service.
•
Global Port Range:
Range of ports on which incoming traffic will be received.
•
Base Host Port:
The port number at the start of the port range your Router should use
when forwarding traffic of the specified type(s) to the internal IP address.
•
Protocol:
Protocol type of Internet traffic, TCP or UDP.
Click the

button.
If you chose Trigger Ports, the Trigger Ports entry screen appears.

Trigger Ports forwards a range of ports to an IP address on the LAN only after specific out-
bound traffic “triggers” the feature. Enter the following information:
•
Service Name:
A unique identifier for the Custom Service.
•
Global Port Range:
Range of ports on which incoming traffic will be received.
•
Local Trigger Port:
Port number of the type of outbound traffic that needs to happen
(will be the trigger) to then allow the configured ports for inbound traffic.
Example
: Set the trigger port to 21 and configure a range of 25 – 110. You would need
to do an outbound ftp before you were able to do an inbound smtp.

Static NAT
This feature allows you to:
•
Direct your Router to forward all externally initiated IP traffic (TCP and UDP protocols
only) to a default host on the LAN.
•
Enable it for certain situations:
– Where you cannot anticipate what port number or packet protocol an in-bound appli-
cation might use. For example, some network games select arbitrary port numbers
when a connection is opened.
– When you want all unsolicited traffic to go to a specific LAN host.

This feature allows you to direct unsolicited or non-specific traffic to a designated LAN sta-
tion. With NAT “On” in the Router, these packets normally would be discarded.
For instance, this could be application traffic where you don’t know (in advance) the port or
protocol that will be used. Some game applications fit this profile.
From the pull-down menu, select the address of the PC that you want to be your default
NAT destination.
Click the
Ne
xt
button, and your choice will be so designated.
