1.8b Development

My Apple TV 2 is showing some odd behaviour in de System Log.
Once or twice a minute it will switch between MAC addresses.

The ATV2 is only connected through wifi (which connects to a Airport Extreme, which connects directly to the m0n0wall box (Soekris net6501-30 model).

Anyone got any idea why this is happening?
It only does this for the ATV2, no other devices.

The reason for this is explained here: http://forum.pfsense.org/index.php/topic,57837.0.html#msg309551

To resolve it, export the m0n0wall configuration and add the following:

Code:

Under the <system> section, add ...

<shellcmd>sysctl net.link.ether.inet.log_arp_movements=0</shellcmd>
<shellcmd>sysctl net.link.ether.inet.log_arp_wrong_iface=0</shellcmd>

Then restore that config.

Sorry about the late reply. Totally missed the topic reply notification mail it seems.

I will give it a go. Read the pfsense topic on it. Weird stuff.

Thanks anyway!
