| 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. |
