NETGEAR FVS318G Reference Manual page 207

Without port triggering, the response from the external application would be treated as a new
connection request rather than a response to a request from the LAN network. As such, it
would be handled in accordance with the inbound port forwarding rules and most likely would
be blocked.
Note these restrictions on port triggering:
• Only one computer can use a port triggering application at any time.
• After a computer finishes using a port triggering application, a short time-out period
passes before the application can be used by another computer. This time-out period is
required so the VPN firewall can determine that the application terminates.
Note: For additional ways of allowing inbound traffic, see
page 130.
To add a port triggering rule:

1. Log in to the unit:
a. In the address field of any of the qualified web browsers, enter https://192.168.1.1.
The NETGEAR Configuration Manager Login screen displays.
b. In the Username field, enter admin and in the Password / Passcode field, enter
password.
Use lowercase letters. If you changed the password, enter your personalized
password. Leave the domain as it is (geardomain).
c. Click the Login button.
The Router Status screen displays. After five minutes of inactivity, which is the default
login time-out, you are automatically logged out.
2. Select Security > Port Triggering.
