ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
Note these restrictions on port triggering:
•Only one computer can use a port-triggering application at any time.
•After a computer has finished using a port-triggering application, there is a short time-out
period before the application can be used by another computer. This time-out period is
required so the wireless VPN firewall can determine that the application has terminated.
Note: For additional ways of allowing inbound traffic, see Inbound Rules
(Port Forwarding) on page 130.
