 | 11 | 	  If you say Y here, then your Linux box will be able to act as an | 
 | 12 | 	  Ethernet bridge, which means that the different Ethernet segments it | 
 | 13 | 	  is connected to will appear as one Ethernet to the participants. | 
 | 14 | 	  Several such bridges can work together to create even larger | 
 | 15 | 	  networks of Ethernets using the IEEE 802.1 spanning tree algorithm. | 
 | 16 | 	  As this is a standard, Linux bridges will cooperate properly with | 
 | 17 | 	  other third party bridge products. | 
 | 18 |  | 
 | 19 | 	  In order to use the Ethernet bridge, you'll need the bridge | 
 | 20 | 	  configuration tools; see <file:Documentation/networking/bridge.txt> | 
 | 21 | 	  for location. Please read the Bridge mini-HOWTO for more | 
 | 22 | 	  information. | 
 | 23 |  | 
 | 24 | 	  If you enable iptables support along with the bridge support then you | 
 | 25 | 	  turn your bridge into a bridging IP firewall. | 
 | 26 | 	  iptables will then see the IP packets being bridged, so you need to | 
 | 27 | 	  take this into account when setting up your firewall rules. | 
 | 28 | 	  Enabling arptables support when bridging will let arptables see | 
 | 29 | 	  bridged ARP traffic in the arptables FORWARD chain. | 
 | 30 |  | 
 | 31 | 	  To compile this code as a module, choose M here: the module | 
 | 32 | 	  will be called bridge. | 
 | 33 |  | 
 | 34 | 	  If unsure, say N. |
