Re: INFO: Port Triggering - What is it?
said by JrC384k:Except for broadcast functions I've never seen a case of a port forwarding to all LAN PCs. Is this what you mean? It would take one incoming packet generating several (1 addressed to each), right? If it's TCP which PC ack do you use?
I thought it works like this: An inbound (inbound from the internet for example) from ports xxx-xxx opens ports xxx-xxx on all LAN PCs.
I found Forwarding always overrides Triggering - could that be what you see? Please elaborate what happened, I'm curious.
Traditional Port Triggering is only LAN generated although packets from the internet "keeps it going" in this case. One thing I didn't try was if the source port of an incoming access to, say, your HTTP server was in a Trigger Range if your server reply would trigger! Hmmm... I'd call that a bug if it did. See what I mean?...
Say you had the IRC (6660-6670) Trigger.
MSIE(6667) --TCP--> JrCSite(80)
Your server replies:
JrCSite(80) --ACK--> MSIE(6667)
Will your ACK trigger Port 6667? I'd like to test this - not easy!
