Sam Ravnborg6a2e9b72005-07-11 21:13:56 -0700[diff] [blame]12 If you say Y here, then your Linux box will be able to act as an
13 Ethernet bridge, which means that the different Ethernet segments it
14 is connected to will appear as one Ethernet to the participants.
15 Several such bridges can work together to create even larger
16 networks of Ethernets using the IEEE 802.1 spanning tree algorithm.
17 As this is a standard, Linux bridges will cooperate properly with
18 other third party bridge products.
19
20 In order to use the Ethernet bridge, you'll need the bridge
Mauro Carvalho Chehabc03e2fa2018-09-17 15:02:34 -0400[diff] [blame]21 configuration tools; see <file:Documentation/networking/bridge.rst>
Sam Ravnborg6a2e9b72005-07-11 21:13:56 -0700[diff] [blame]22 for location. Please read the Bridge mini-HOWTO for more
23 information.
24
25 If you enable iptables support along with the bridge support then you
26 turn your bridge into a bridging IP firewall.
27 iptables will then see the IP packets being bridged, so you need to
28 take this into account when setting up your firewall rules.
29 Enabling arptables support when bridging will let arptables see
30 bridged ARP traffic in the arptables FORWARD chain.
31
32 To compile this code as a module, choose M here: the module
33 will be called bridge.

35 If unsure, say N.
