|  | 10 | If you say Y here, then your Linux box will be able to act as an | 
|  | 11 | Ethernet bridge, which means that the different Ethernet segments it | 
|  | 12 | is connected to will appear as one Ethernet to the participants. | 
|  | 13 | Several such bridges can work together to create even larger | 
|  | 14 | networks of Ethernets using the IEEE 802.1 spanning tree algorithm. | 
|  | 15 | As this is a standard, Linux bridges will cooperate properly with | 
|  | 16 | other third party bridge products. | 
|  | 17 |  | 
|  | 18 | In order to use the Ethernet bridge, you'll need the bridge | 
|  | 19 | configuration tools; see <file:Documentation/networking/bridge.txt> | 
|  | 20 | for location. Please read the Bridge mini-HOWTO for more | 
|  | 21 | information. | 
|  | 22 |  | 
|  | 23 | If you enable iptables support along with the bridge support then you | 
|  | 24 | turn your bridge into a bridging IP firewall. | 
|  | 25 | iptables will then see the IP packets being bridged, so you need to | 
|  | 26 | take this into account when setting up your firewall rules. | 
|  | 27 | Enabling arptables support when bridging will let arptables see | 
|  | 28 | bridged ARP traffic in the arptables FORWARD chain. | 
|  | 29 |  | 
|  | 30 | To compile this code as a module, choose M here: the module | 
|  | 31 | will be called bridge. | 
|  | 32 |  | 
|  | 33 | If unsure, say N. |
