12 filtering/NAT/brouting on the Ethernet bridge.
19 config BRIDGE_EBT_BROUTE

95 equivalent of the iptables limit match.
97 If you want to compile it as a module, say M here and read
98 <file:Documentation/kbuild/modules.txt>. If unsure, say `N'.
100 config BRIDGE_EBT_MARK
101 tristate "ebt: mark filter support"
103 This option adds the mark match, which allows matching frames based on
104 the 'nfmark' value in the frame. This can be set by the mark target.
105 This value is the same as the one used in the iptables mark match and
108 To compile it as a module, choose M here. If unsure, say N.
110 config BRIDGE_EBT_PKTTYPE
111 tristate "ebt: packet type filter support"
113 This option adds the packet type match, which allows matching on the
114 type of packet based on its Ethernet "class" (as determined by
115 the generic networking code): broadcast, multicast,
116 for this host alone or for another host.
118 To compile it as a module, choose M here. If unsure, say N.
120 config BRIDGE_EBT_STP
121 tristate "ebt: STP filter support"
123 This option adds the Spanning Tree Protocol match, which
124 allows STP header field filtering.
126 To compile it as a module, choose M here. If unsure, say N.
128 config BRIDGE_EBT_VLAN
129 tristate "ebt: 802.1Q VLAN filter support"
131 This option adds the 802.1Q vlan match, which allows the filtering of
134 To compile it as a module, choose M here. If unsure, say N.
138 config BRIDGE_EBT_ARPREPLY
139 tristate "ebt: arp reply target support"
140 depends on BRIDGE_NF_EBTABLES && INET
142 This option adds the arp reply target, which allows
143 automatically sending arp replies to arp requests.
145 To compile it as a module, choose M here. If unsure, say N.
147 config BRIDGE_EBT_DNAT
148 tristate "ebt: dnat target support"
150 This option adds the MAC DNAT target, which allows altering the MAC
151 destination address of frames.
153 To compile it as a module, choose M here. If unsure, say N.
155 config BRIDGE_EBT_MARK_T
156 tristate "ebt: mark target support"
158 This option adds the mark target, which allows marking frames by
159 setting the 'nfmark' value in the frame.
160 This value is the same as the one used in the iptables mark match and
163 To compile it as a module, choose M here. If unsure, say N.
165 config BRIDGE_EBT_REDIRECT
166 tristate "ebt: redirect target support"
168 This option adds the MAC redirect target, which allows altering the MAC
169 destination address of a frame to that of the device it arrived on.
171 To compile it as a module, choose M here. If unsure, say N.
173 config BRIDGE_EBT_SNAT
174 tristate "ebt: snat target support"
176 This option adds the MAC SNAT target, which allows altering the MAC
177 source address of frames.
179 To compile it as a module, choose M here. If unsure, say N.
183 config BRIDGE_EBT_LOG
184 tristate "ebt: log support"
186 This option adds the log watcher, that you can use in any rule
187 in any ebtables table. It records info about the frame header
190 To compile it as a module, choose M here. If unsure, say N.
192 config BRIDGE_EBT_ULOG
193 tristate "ebt: ulog support (OBSOLETE)"
195 This option enables the old bridge-specific "ebt_ulog" implementation
196 which has been obsoleted by the new "nfnetlink_log" code (see
197 CONFIG_NETFILTER_NETLINK_LOG).
199 This option adds the ulog watcher, that you can use in any rule
200 in any ebtables table. The packet is passed to a userspace
201 logging daemon using netlink multicast sockets. This differs
202 from the log watcher in the sense that the complete packet is
203 sent to userspace instead of a descriptive text and that
204 netlink multicast sockets are used instead of the syslog.
206 To compile it as a module, choose M here. If unsure, say N.
208 config BRIDGE_EBT_NFLOG
209 tristate "ebt: nflog support"
211 This option enables the nflog watcher, which allows to LOG
212 messages through the netfilter logging API, which can use
213 either the old LOG target, the old ULOG target or nfnetlink_log
216 This option adds the nflog watcher, that you can use in any rule
217 in any ebtables table.
219 To compile it as a module, choose M here. If unsure, say N.
