I am running into a big issue at a small network i manage. This network is an Apple network, with airport extremes, expresses, mac book pro's, imac's, ipads, iphones etc...
I went to add something to this network today and noticed lights flashing like crazy on the switch. After noticing this I started wireshark and took a look at my firewall log file.
The line I see in the log files over and over is
Deny 10.0.3.100 188.8.131.52 mdns/udp 5353 5353 1-Trusted Firebox udp flooding 123 255 (Internal Policy) proc_id="firewall" rc="101"
The source ip changes (10.0.3.100) but the message stays the same.
I am having a big issue figuring out what is causing this. When i have my wireless accesspoints connected i can not connect to anything on the network. When i unplug them the network is ok and is not saturated with this traffic.
Anyone have any good ways to go about diagnosing this issue? I am not sure if this just started or if it has always been the case since i just noticed it now.
UPDATE: The message that i see when i ran wireshark is the following:
25 0.006498000 10.0.3.3 184.108.40.206 MDNS 135 Standard query response 0x0000 A, cache flush 10.0.3.3 A, cache flush 169.254.233.55
