NOTES:
• When connecting to an IRC server, a client PC makes an outgoing
connection using the trigger port range 66660-7000. The IRC server
responds by verifying the username and creating a new connection
to the client PC using an incoming port.
• If Port Trigger is disabled, the router drops the connection because
it is unable to determine which PC is requesting for IRC access.
When Port Trigger is enabled, the router assigns an incoming port to
receive the inbound data. This incoming port closes once a specific
time period has elapsed because the router is unsure when the
application has been terminated.
• Port triggering only allows one client in the network to use a
particular service and a specific incoming port at the same time.
• You cannot use the same application to trigger a port in more than
one PC at the same time. The router will only forward the port back
to the last computer to send the router a request/trigger.
