depends on BRIDGE && BRIDGE_NETFILTER
config BRIDGE_NF_EBTABLES
tristate "Ethernet Bridge tables (ebtables) support"
help
ebtables is a general, extensible frame/packet identification
framework. Say 'Y' or 'M' here if you want to do Ethernet
filtering/NAT/brouting on the Ethernet bridge.
#
# tables
#
config BRIDGE_EBT_BROUTE
tristate "ebt: broute table support"
depends on BRIDGE_NF_EBTABLES
help
The ebtables broute table is used to define rules that decide between
bridging and routing frames, giving Linux the functionality of a
brouter. See the man page for ebtables(8) and examples on the ebtables
website.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_T_FILTER
tristate "ebt: filter table support"
depends on BRIDGE_NF_EBTABLES
help
The ebtables filter table is used to define frame filtering rules at
local input, forwarding and local output. See the man page for
ebtables(8).
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_T_NAT
tristate "ebt: nat table support"
depends on BRIDGE_NF_EBTABLES
help
The ebtables nat table is used to define rules that alter the MAC
source address (MAC SNAT) or the MAC destination address (MAC DNAT).
See the man page for ebtables(8).
To compile it as a module, choose M here. If unsure, say N.
#
# matches
#
config BRIDGE_EBT_802_3
tristate "ebt: 802.3 filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds matching support for 802.3 Ethernet frames.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_AMONG
tristate "ebt: among filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the among match, which allows matching the MAC source
and/or destination address on a list of addresses. Optionally,
MAC/IP address pairs can be matched, f.e. for anti-spoofing rules.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_ARP
tristate "ebt: ARP filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the ARP match, which allows ARP and RARP header field
filtering.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_IP
tristate "ebt: IP filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the IP match, which allows basic IP header field
filtering.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_LIMIT
tristate "ebt: limit match support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the limit match, which allows you to control
the rate at which a rule can be matched. This match is the
equivalent of the iptables limit match.
If you want to compile it as a module, say M here and read
<file:Documentation/kbuild/modules.txt>. If unsure, say `N'.
config BRIDGE_EBT_MARK
tristate "ebt: mark filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the mark match, which allows matching frames based on
the 'nfmark' value in the frame. This can be set by the mark target.
This value is the same as the one used in the iptables mark match and
target.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_PKTTYPE
tristate "ebt: packet type filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the packet type match, which allows matching on the
type of packet based on its Ethernet "class" (as determined by
the generic networking code): broadcast, multicast,
for this host alone or for another host.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_STP
tristate "ebt: STP filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the Spanning Tree Protocol match, which
allows STP header field filtering.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_VLAN
tristate "ebt: 802.1Q VLAN filter support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the 802.1Q vlan match, which allows the filtering of
802.1Q vlan fields.
To compile it as a module, choose M here. If unsure, say N.
#
# targets
#
config BRIDGE_EBT_ARPREPLY
tristate "ebt: arp reply target support"
depends on BRIDGE_NF_EBTABLES && INET
help
This option adds the arp reply target, which allows
automatically sending arp replies to arp requests.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_DNAT
tristate "ebt: dnat target support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the MAC DNAT target, which allows altering the MAC
destination address of frames.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_MARK_T
tristate "ebt: mark target support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the mark target, which allows marking frames by
setting the 'nfmark' value in the frame.
This value is the same as the one used in the iptables mark match and
target.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_REDIRECT
tristate "ebt: redirect target support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the MAC redirect target, which allows altering the MAC
destination address of a frame to that of the device it arrived on.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_SNAT
tristate "ebt: snat target support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the MAC SNAT target, which allows altering the MAC
source address of frames.

#
# watchers
#
config BRIDGE_EBT_LOG
tristate "ebt: log support"
depends on BRIDGE_NF_EBTABLES
help
This option adds the log watcher, that you can use in any rule
in any ebtables table. It records info about the frame header
to the syslog.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_ULOG
tristate "ebt: ulog support (OBSOLETE)"
depends on BRIDGE_NF_EBTABLES
help
This option enables the old bridge-specific "ebt_ulog" implementation
which has been obsoleted by the new "nfnetlink_log" code (see
CONFIG_NETFILTER_NETLINK_LOG).
This option adds the ulog watcher, that you can use in any rule
in any ebtables table. The packet is passed to a userspace
logging daemon using netlink multicast sockets. This differs
from the log watcher in the sense that the complete packet is
sent to userspace instead of a descriptive text and that
netlink multicast sockets are used instead of the syslog.
To compile it as a module, choose M here. If unsure, say N.
config BRIDGE_EBT_NFLOG
tristate "ebt: nflog support"
depends on BRIDGE_NF_EBTABLES
help
This option enables the nflog watcher, which allows to LOG
messages through the netfilter logging API, which can use
either the old LOG target, the old ULOG target or nfnetlink_log
as backend.
This option adds the ulog watcher, that you can use in any rule
in any ebtables table.
To compile it as a module, choose M here. If unsure, say N.
