    FTP Help - cannot go TO ftp sites

    FTP sites work fine with the default Firewall settings, so unless you've disallowed FTP in the Firewall Settings -> Network Services Filter tab, it's not likely to be your router. It's much more likely to be your Windows Firewall settings. You must allow FTP, or the application you're using to...

    RT66U Firing ARP-Requests all day (Waking my Synology NAS from Sleep)

    I'm curious... I have a similar issue (see here http://forums.smallnetbuilder.com/showthread.php?t=9792 ). I wonder if that's the same issue. Are you sure it's the router initiating these ARP broadcasts and not just forwarding them on from other devices?

    Any way to block ARP broadcast forwarding on a specific hardware port?

    See above. The device that generates it is the Arduino. You can tell that that because the source MAC address is that of the Arduino. To be absolutely clear even if the Arduino is plugged directly via a crossover lead into my laptop, and both have a static IP, it still does this.

    Any way to block ARP broadcast forwarding on a specific hardware port?

    The arduino isn't an "arpwatch enabled device". Arpwatch is a network tool used to monitor ARP behaviour on the network. So, a network administrator might install arpwatch on their Linux box, but it certainly doesn't come as part of the Arduino Ethernet library. It's standard behaviour to do...

    Any way to block ARP broadcast forwarding on a specific hardware port?

    Everything is static and DHCP is off on my routers. It's not an IP conflict - even if I radically change the Arduino's IP (e.g. to 10.0.0.X) and unplug the rest of the network it still does it.

    Any way to block ARP broadcast forwarding on a specific hardware port?

    The device sending out the ARP broadcasts is the Arduino Ethernet (and also a DVR security system that has the same issue, it runs an embedded Linux). iptables can't block ARPs, but of course arptables can...

    Any way to block ARP broadcast forwarding on a specific hardware port?

    I have device on my network that stupidly sends out ARP broadcasts every second asking who has its own IP address (below is a record from a Wireshark capture): 32:bd:9f Broadcast ARP Who has 192.168.0.21? Tell 0.0.0.0 This is not related to DHCP (I have that off and the device has a...
