BEFSR11 port triggering and FW 1.39 and 1.40.1.Can anyone confirm the following?
I believe I'm having a problem with port triggering. This feature works great until I try to use the same outgoing trigger to open 2 different ports or range of ports. When I configure the router to use the same trigger for 2 or more incoming port(s), the second entry using the same outgoing trigger never gets forwarded. Does anyone else use port triggering? If you do, can you successfully use the same outgoing trigger to open 2 or more ports or range of ports?
Generic Example:
------------/trigger\----/incoming port(s)\ Example 1: 2000-2000 = 5000-6000 Example 2: 2000-2000 = 7000-7000
If I use a different trigger for #2, port 7000 gets forwarded. Otherwise, if I use the same trigger for both, like the example above, 7000 will not be forwarded. |

I can confirm. Apparently, even if the trigger range is different, if 1 trigger is active no others can occur. |

Really? I'm almost 100% positive I've witnessed 2 or more different triggers working at the same time. Such as incoming ports for ICQ xfers and MS Gaming Zone. One trigger is for ICQ (5190), other is for Gaming Zone (28800). Both seem to work fine. Back to back, I can receive files and play games on the zone and visa versa. Do you mean that multiple triggers cannot occur simultaneously? |

I'd try it again but I'm on f/w 1.30 (no Port Triggering) I'm pretty sure this failed to work trying to get IRC DCC via Port Triggering.... 6666-6666 triggers 50000-50003 6668-6668 triggers 50004-50007 One machine IRC connects 6666 the other 6668. Now, I assumed I could have both machines do DCC but it didn't work. I could have goofed sompin of course. |

Yeah, I noticed you got fed up with the latest f/w offerings and went back to 1.30. Tonight, I'll try to verify the ICQ/MSGZ ability I mentioned above. I wished the Linksys Techs would provide the proper details as to the functionality and limitations of the port triggering for those, such as I, that have requested it in the past. |

Yeah... I don't think LinkSys engineering knows, either, is the problem. We're on our own. If you'd like to compare notes, I characterized it briefly, here: INFO: Port Triggering - What is it?One nice thing is SPI doesn't affect Port Triggering while it does static forwarding and DMZ - another "undocumented feature". |

Thanks for the link. Very useful info. Yeah, it's a total bummer 2 PCs can't use the same trigger port(s) and incoming port(s) at the same time. I think a feature called 'NAT trigger tags' is required for multiple LAN PC's to use the same inbound ports simultaneously behind a NAT box. I'll get a friend to send me a file via ICQ, then I'll try to play a game on the Zone. This should work like it has in the past. Irregardless of the outcome, I'll add to your port triggering thread. Thanks Bill [text was edited by author 2001-10-08 14:03:26] |

Since you found the key, Frosty, that IRC-DCC thing I tried *should* have worked. You convinced me I probably goofed trying it. EDIT: And great addition to the other thread! Please add all you find. [text was edited by author 2001-10-09 00:41:02] |

I think you're on top of what I was originally looking for - where the outbound trigger's IP destination allows that IP (and only that IP) to forward back. This way, only attempting the same server would conflict. |

Cool. Thanks. I know what you mean. I remember reading about a so-called trigger tag feature. The code apparently makes a table of LAN IPs, MAC addys, and the common inbound ports. Somehow it 'tags' the outbound packet, so the return packet can be sent to the proper LAN PC. [text was edited by author 2001-10-09 01:14:33] |
