Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 35 | <DT>What is ebtables?</DT> |
| 36 | <DD>The ebtables project is the Linux 2.5.x (and above) Link Layer |
| 37 | firewalling subsystem, a patch for 2.4.x is maintained too. |
| 38 | It delivers for Linux the functionality of |
fnm3 | 81d84b6 | 2003-02-08 15:08:34 +0000 | [diff] [blame] | 39 | Ethernet frame filtering, all kinds of frame NAT (Network Address |
Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 40 | Translation) and frame matching. The ebtables infrastructure is |
| 41 | a part of the standard Linux 2.5.x (and above) kernels.</DD> |
Bart De Schuymer | 38b9d6d | 2003-11-09 20:55:03 +0000 | [diff] [blame^] | 42 | <DT>Why would I use it?</DT> |
Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 43 | <DD>To filter frames by MAC-address or frame type at |
| 44 | Link Layer inside your Linux-based Ethernet bridge, to do |
| 45 | some basic filtering of certain protocol headers, to |
| 46 | make a Linux brouter.</DD> |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 55 | <DD>First step is to decide what kernel version to use. If you |
| 56 | want to use a 2.5.x (or above) kernel, then just use the latest |
| 57 | and greatest kernel version. You won't have to patch the kernel. |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 74 | tool. This ebtables binary is used to make filtering |
| 75 | rules for the Linux-based Ethernet bridge. All traffic entering |
| 76 | or leaving on a bridge port will be seen by the rules. The ebtables usage is very |
fnm3 | 81d84b6 | 2003-02-08 15:08:34 +0000 | [diff] [blame] | 77 | similar to the iptables, so it should not be so hard. Of |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 99 | <DD>Yes, it's possible to filter on the ARP header, using ebtables. |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 115 | <DT>When using the option --Lc, what does the pcnt value represent?</DT> |
| 116 | <DD> |
| 117 | Normally, pcnt will represent the number of frames that matched this rule. However, |
| 118 | if IP connection tracking is enabled, all fragmented IP packets will first be |
| 119 | defragmented. Therefore, the pcnt value for IP packets will then represent the |
| 120 | number of matched IP packets, not the number of matched frames containing IP fragments. |
| 121 | In the BROUTING chain however, pcnt will always represent the number of matched frames, since |
| 122 | the IP connection tracking is not done before this chain is traversed. |
| 123 | </DD> |
| 124 | <DT>What is this brouter stuff and when is it useful?</DT> |
| 125 | <DD> |
| 126 | The ebtables BROUTING chain gets traversed very early, namely right after a frame |
| 127 | is received on a forwarding bridge port. If a rule's decision is to route the frame, |
| 128 | the input device will remain the physical device of the bridge port and the bridge |
| 129 | code won't touch the frame. The frame will be processed by the network stack. If the |
| 130 | decision is to bridge the frame (the default behaviour), then the input device will |
| 131 | become the bridge device on which the port is enslaved and the bridge code will decide |
| 132 | what to do with the frame.</DD> |
| 133 | <DT>So, what's the difference between the ebtables BROUTING and PREROUTING chains?</DT> |
| 134 | <DD>The ebtables PREROUTING chain is only traversed when the bridge code is deciding what |
| 135 | to do with the frame. So, if a BROUTING chain rule decided the frame should be routed, then |
| 136 | the ebtables PREROUTING chain won't see it. See the |

| 140 | devices, what's wrong?</DT> |
| 141 | <DD> |
| 142 | There is one difference between the br-nf behaviour in the 2.5.x or higher kernels and |
| 143 | the 2.4.x patch. To get the br-nf code accepted into the standard 2.5.x kernels, we had to |
| 144 | remove the code that automatically checked on the bridge port in the iptables port checking |
Bart De Schuymer | 38b9d6d | 2003-11-09 20:55:03 +0000 | [diff] [blame^] | 145 | code (options -i and -o). Instead there is now an iptables match module, called 'physdev', that |
| 146 | can be used to filter on the bridge ports. This match module has some extra options and |
| 147 | is in the standard 2.6 kernels, the corresponding userspace module is available in the |
| 148 | iptables userspace tool. See the iptables man pages and |

| 156 | <DT>I want to use the most recent ebtables code, even if it's not yet in an official release. |
| 157 | How do I do this?</DT> |
| 158 | <DD> |
| 159 | The most recent code is available at the <A href="http://sourceforge.net/projects/ebtables"> |
| 160 | sourceforge ebtables</A> CVS repository. To get a copy of the repository, do the following: |
| 161 | <PRE> |
fnm3 | cd1e2e6 | 2003-02-18 16:44:07 +0000 | [diff] [blame] | 162 | # cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/ebtables login |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 164 | </PRE> |
| 165 | The current userspace code is in the ebtables2/userspace/ebtables2 directory. To compile the |
| 166 | CVS userspace tool you'll need to do the following: |
| 167 | <PRE> |
Bart De Schuymer | 6c97d52 | 2003-02-19 20:09:51 +0000 | [diff] [blame] | 168 | # make KERNEL_INCLUDES=/usr/src/linux/include/ |

Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 170 | </PRE> |
Bart De Schuymer | 38b9d6d | 2003-11-09 20:55:03 +0000 | [diff] [blame^] | 171 | Obviously you'll need to use the right kernel directory.</DD> |
| 172 | <DD> Why is compiling the CVS different? |
Bart De Schuymer | 9ea96e2 | 2003-02-15 13:47:40 +0000 | [diff] [blame] | 173 | Because the kernel include files are not maintained in the userspace directory of the CVS. |
| 174 | When a new ebtables release is made, the kernel include files get copied in the tar file, so |
| 175 | the standard installation knows where to get its kernel include files.</DD> |
Bart De Schuymer | 38b9d6d | 2003-11-09 20:55:03 +0000 | [diff] [blame^] | 176 | <DD>The ebtables CVS tree has its own kernel tree with ebtables related files (for 2.4 and 2.6). |
| 177 | The CVS directory (base_dir)/ebtables2/kernel/linux2.5/include/ can be used for compiling the userspace tool. |
| 178 | </DD> |
| 179 | <DD>New ebtables modules might not yet be in the standard kernel. The CVS directory |
| 180 | (base_dir)/ebtables2/kernel/linux2.5/net/bridge/netfilter/ contains the not yet submitted modules. The modules |
| 181 | that are already in the standard kernel are also in this directory and they are normally in sync with the latest |
| 182 | kernel release. |

| 194 | <DD>Your iptables rules are probably dropping them then. By default, on a Linux bridging firewall all |

| 200 | <DT>I'm getting a message that looks like: ``br_netfilter: Argh!! : bad mac.raw pointer''</DT> |
| 201 | <DD>We sometimes get reports about this message occurring. The bridge-nf code reports this message when a |
| 202 | specific irregularity is observed, in technical terms: the mac.raw pointer of the sk_buff isn't set properly. |
| 203 | The most likely cause of this is the network device driver. Since this only happens for a few persons, the |
| 204 | only way to debug this is if those persons are willing to try patches. Up until now this has not been the case.<BR> |
| 205 | The easiest solution is to try a different type of network card or a different device driver. |

| 223 | 172.16.1.2 is on the eth1 side, .4 on the eth2 side, the <destination> is somewhere on the Internet. |
| 224 | Without the routing table entry (last line above), it is obvious that this DNAT wouldn't work (because the bridge/router |
| 225 | wouldn't know where to send 172.16.1.xx traffic). It is possible that the mentioned |
| 226 | error message gets printed on the screen or in your logs when this routing table entry is omitted. |
