Ignoring Broadcast traffic
Ok so our network has avaya phones all over the place and the DHCP server(separate from mine) is constantly broadcasting over UDP ports 67 and 68, so my NIC is showing a constant influx of connections averaging ~90KBps. Is there any way on my end I can ignore this traffic so I don't show that 90KBps, or am I SOL?

how about some thing like:
Code:
$IPTABLES -A udp_packets -p UDP -i $INET_IFACE -d 255.255.255.255 --destination-port 67:68 -j DROP |
Quote:
sudo iptables -A INPUT -p UDP -i $INET_IFACE -d 255.255.255.255 --destination-port 67:68 -j DROP where: $INET_IFACE is your ip address. Also be advised that many ip addresses can get used for broadcasting. I don't know what your Avaya traffic uses. So be prepared to replace the 255.255.255.255 with that address too. Note also this will shut off ALL broadcasts, including those from printers coming online, misc other servers, lotsa things (anything that might be using 255.255.255.255). You need to stay aware of that too. |
