大家好，我想家配置一个从eth4收到包后再从eth4发送出去。  查了最新的brctl有支持 haipin 功能。

原命令说明如下：
Usage: brctl [commands]
commands:
      addbr          <bridge>             add bridge
      delbr          <bridge>             delete bridge
      addif          <bridge> <device>    add interface to bridge
      delif          <bridge> <device>    delete interface from bridge
      hairpin       <bridge> <port> {on|off}       turn hairpin on/off
      setageing    <bridge> <time>       set ageing time
      setbridgeprio <bridge> <prio>       set bridge priority
      setfd          <bridge> <time>       set bridge forward delay
      sethello       <bridge> <time>       set hello time
      setmaxage    <bridge> <time>       set max message age
      setpathcost    <bridge> <port> <cost>  set path cost
      setportprio    <bridge> <port> <prio>  set port priority
      show          [ <bridge> ]          show a list of bridges
      showmacs       <bridge>             show a list of mac addrs
      showstp       <bridge>             show bridge stp info
      stp          <bridge> {on|off}    turn stp on/off

我没有成功配置 hairpin.  我的命令如下。  求大家帮助:
brctl addbr br0
brctl addif br0 eth4
brctl hairpin br0 eth4 on

ifconfig br0 10.10.0.12 netmask 255.255.255.0 up
ifconfig br0:1 53.53.0.12 netmask 255.255.240.0 up
ifconfig eth4 up

cat  /etc/sysconfig/network-scripts/ifcfg-eth4
DEVICE=eth4
BOOTPROTO=none
ONBOOT=yes
PROMISC=yes
BRIDGE=br0

cat  /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.10.0.12
BROADCAST=10.10.0.255
NETMASK=255.255.255.0

cat  /etc/sysconfig/network-scripts/ifcfg-br0:1
DEVICE=br0:1
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=none
IPADDR=53.53.0.12
NETMASK=255.255.240.0

Sorry. 这个功能在rhel 7支持。之前我装在rhel6.1上了。命令本身是对的。
