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

32 | If unsure, say N. |
