    I'm demoing LNS and trying to set up my new Squeezebox and Squeezeserver. From Logitech, the following needs to be allowed:

    Name: SqueezeCenter Discovery – Port number: 3483 – Protocol: UDP
    Name: SqueezeCenter Control – Port number: 3483 – Protocol: TCP
    Name: SqueezeCenter Web – Port Number: 9000 – Protocol: TCP

    I have made two rules for the above ports, incoming and outgoing, and allowed IP addresses in my local LAN's range of 192.168.1.100 to 192.168.1.125, and placed them at the top of my ruleset.

    The first rule allows TCP, port 9000 and is at the top. The second rule allows UDP or TCP port 3483 and is below the first. The PC (Squeezeserver) IP address is 192.168.1.101 and the Squeezebox is at 192.168.1.109, both are within the IP range I have allowed.

    My log shows that the rule for blocking "Any other UDP packets" is blocking broadcasts from my server PC to the Squeezebox located at 192.168.1.109, UDP 3483. I don't understand this since I have a rule before it that specifically permits UDP to and from this port.

    My log also shows that the "Any other TCP packet" rule is blocking attempts from the Squeezebox (190.168.1.109) destined to port 9000. I also don't understand this since I have specifically allowed this port.

    I have saved and applied all rules. I'll provide any more information as requested. Thanks in advance for the help!

    Hi stangbat
    Can you provide the log?

    Do you mean the destination address is 255.255.255.255 ?

    Yes, in looking at the log file I see it says 255.255.255.255. The log tab in the application just say Broadcast but when I track source it also says 255.255.255.255.

    Here is a portion of the log showing everything that gets rejected:

    Code:

    Okay, I got things working but I don't know if this is the best way to do it. Here are the rules I created:

    http://img224.imageshack.us/my.php?image=lnssbrulessc6.jpg

    In addition, the Squeezebox constantly broadcasts its presence on the LAN so that it can be woken up by the Squeezeserver. There is no way to stop this. So LNS was constantly rejecting UDP packets for port 3483. So I modified the "Any other UDP packet" rule and the "All other packets" rule as seen below so that my logs didn't constantly have this port showing up and so LNS didn't have to constantly block it. Is this the correct way of handling something like this?

    I'm afraid that didn't work. Now I have no connectivity between the PC and the SB, however the connection attempts in the log are drastically smaller than without that rule you suggested. It looks like the broadcast from the PC is getting blocked? Log:

    Code:
    01-05-09,08:17:04  U-10   'UDP : Any other UDP pack' 255.255.255.255   UDP       Ports Dest:3483 Src:3483
    01-05-09,08:18:04  U-11   'UDP : Any other UDP pack' 255.255.255.255   UDP       Ports Dest:3483 Src:3483
    01-05-09,08:19:04  U-12   'UDP : Any other UDP pack' 255.255.255.255   UDP       Ports Dest:3483 Src:3483
    01-05-09,08:20:04  U-13   'UDP : Any other UDP pack' 255.255.255.255   UDP       Ports Dest:3483 Src:3483

    I know I shouldn't be modifying those two rules. After I shut the computer down last night and was thinking about it I realized that I went about it the wrong way.

    Thanks for trying to help, 1hui. Still no luck. I applied the rule you suggested and I'm still seeing broadcast packets being blocked. For some reason now I'm also seeing UDP packets from port 8900 on the Squeezebox.

    I did a factory reset on the Squeezebox and I'm seeing some "nul" packets too when it is trying to find the Squeezecenter server. It never can find it.

    Code:
    01-05-09,11:24:53  D-33   'UDP : Any other UDP pack' 0.0.0.0           UDP       Ports Dest:3483 Src:3483
    01-05-09,12:25:25  U-34   'UDP : Any other UDP pack' 255.255.255.255   UDP       Ports Dest:3483 Src:3483
    01-05-09,12:29:09  D-35   'UDP : Any other UDP pack' 0.0.0.0           UDP       Ports Dest:3483 Src:3483
    01-05-09,12:29:09  D-36   'UDP : Any other UDP pack' 0.0.0.0           UDP       Ports Dest:3483 Src:3483
    01-05-09,12:29:10  D-37   'UDP : Any other UDP pack' 0.0.0.0           UDP       Ports Dest:3483 Src:3483
    I freely admit that I don't understand this stuff as good as I should, but I'm trying. It is getting really frustrating.

    Edit, trying to connect to UDP port 8900, not TCP.

    Okay, maybe I've got this taken care of. I looked over the filter rules again (for the 100+th time) and this time I noticed that the red "stop forbidden packets" icon was next to the two rules. Doh! So the rule was obviously stopping the packets as I've been reporting instead of allowing them. At least this is what I think was happening. Right now the Squeezebox is playing audio from my PC with all filters enabled and with nothing showing up in the log. Fingers crossed.
