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

31 | If unsure, say N. |
