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.

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.

28 To compile this code as a module, choose M here: the module
29 will be called bridge.
