   WoL is provided through the Ethtool* utility. Ethtool is included with Red
   Hat* 8.0. For other Linux distributions, download and install Ethtool from

+  Multiple Interfaces on Same Ethernet Broadcast Network
+  ------------------------------------------------------
+
+  Due to the default ARP behavior on Linux, it is not possible to have
+  one system on two IP networks in the same Ethernet broadcast domain
+  (non-partitioned switch) behave as expected. All Ethernet interfaces
+  will respond to IP traffic for any IP address assigned to the system.
+  This results in unbalanced receive traffic.
+
+  If you have multiple interfaces in a server, either turn on ARP
+  filtering by
+
+  (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+      (this only works if your kernel's version is higher than 2.4.5), or
+
+  (2) installing the interfaces in separate broadcast domains (either
+      in different switches or in a switch partitioned to VLANs).
