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

| ---help--- | |
| If you say Y here, then the Ethernet bridge will be able selectively | |
| forward multicast traffic based on IGMP/MLD traffic received from | |
| each port. | |
| Say N to exclude this support and reduce the binary size. | |
| If unsure, say Y. | |
| config BRIDGE_VLAN_FILTERING | |
| bool "VLAN filtering" | |
| depends on BRIDGE | |
| depends on VLAN_8021Q | |
| default n | |
| ---help--- | |
| If you say Y here, then the Ethernet bridge will be able selectively | |
| receive and forward traffic based on VLAN information in the packet | |
| any VLAN information configured on the bridge port or bridge device. | |
| Say N to exclude this support and reduce the binary size. | |
| If unsure, say Y. |
