| 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. | |

| 31 | To compile this code as a module, choose M here: the module | |
| 32 | will be called bridge. | |

| 34 | If unsure, say N. | |
