命令和错误信息：
gtwy ~ # ip rule add from 64.251.23.186 table t1
RTNETLINK answers: Operation not supported
较旧的文章有同样的问题，但它对我没有帮助：http://forums.gentoo.org/viewtopic-t-696982-start-0-postdays-0-postorder-asc-highlight-.html
我花了大量时间在 Google 上搜索，试图找到解决方案。好像我的内核配置缺少了一些东西？任何帮助或想法都将不胜感激。我的系统/内核是：2.6.36-gentoo-r5 #3 SMP Thu Jan 13 10:49:06 EST 2011 x86_64 Intel(R) Xeon(R) CPU X3220 @ 2.40GHz GenuineIntel GNU/Linux。
我将此发布在 SuperUser 上，因为该系统用作工作站，并且此问题与服务器专门处理的特定任务无关。
